Vaisala humicAp® sensor for measuring

Relative humidity

In 1973, Vaisala introduced HUMICAP

®

, the world’s first thinfilm capacitive humidity sensor. Since then, Vaisala has become the market leader in relative humidity measurements, and thin-film capacitive humidity sensors have developed from one company’s innovation into a global industry standard.

Vaisala HUMICAP sensors guarantee quality and reliability, with their reputation for accuracy, excellent long-term stability, and negligible hysteresis.

how it works

HUMICAP is a capacitive thin-film polymer sensor consisting of a substrate on which a thin film of polymer is deposited between two conductive electrodes. The sensing surface is coated with a porous metal electrode to protect it from contamination and exposure to condensation. The substrate is typically glass or ceramic.

The thin-film polymer either absorbs or releases water vapor as the relative humidity of the ambient air rises or falls. The dielectric properties of the polymer film depend on the amount of absorbed water. As the relative humidity around the sensor changes, the dielectric properties of the polymer film change, and so does the capacitance of the sensor. The instrument’s electronics measure the capacitance of the sensor and convert it into a humidity reading.

typical Applications for humidity measurement

Vaisala’s humidity instruments with

HUMICAP sensors are suitable for a wide range of applications. From power and steel to life sciences and building automation, many industries need to measure humidity – here are just a few:

Humidity must be measured and controlled in many drying processes, such as those in construction material and paper manufacturing, and fluid bed dryers. The humidity of the process air is a good indicator of the progression of the drying process.

specifications. In addition, glove boxes and isolators – used for handling moisture or gas-sensitive materials

– benefit from accurate and reliable humidity measurements. Measuring humidity in a critical environment can be especially challenging.

In the food industry the dryers and ovens used in bread baking and cereal manufacture require a carefully controlled humidity level to maintain consistent quality and high yield, and to give distinctive characteristics to the finished product.

In building automation, optimizing both the temperature and relative humidity of the indoor environment enables a greater level of comfort for occupants than optimizing temperature alone. Careful humidity control is a must in museums, archives, warehouses, and other environments where humiditysensitive materials are stored.

Structure of the HUMICAP sensor.

Until the early 1970s, hair hygrometers were commonly used in radiosondes. At that time, reliable humidity measurement was an unresolved challenge and to solve this, Vaisala began developing a new type of humidity sensor using semiconductors and thin-film materials. The revolutionary HUMICAP humidity sensor was introduced two years later, in 1973, at CIMO VI congress.

HUMICAP® – The Story of Innovation

the sensor had no moving parts, and due to the advanced use of semiconductor and thin-film technologies, it was amazingly small. The sensor had a fast response time, good linearity, low hysteresis, and small temperature coefficiency. museums. The need for reliable humidity measurement was common to all, and instruments that could do this accurately were few and far between.

HUMICAP was a radical innovation that changed humidity measurements for good. The new technology was groundbreaking:

Despite the fact that the innovation was designed for a new type of a radiosonde, the greatest interest came from elsewhere: people working in environments as diverse as greenhouses, bakeries, warehouses, construction sites, brick and timber kilns, and

By 1980, a variety of products based on HUMICAP technology

– from hand-held meters to industrial transmitters, calibrators, and other accessories – were being sold in over 60 countries.

Since its birth, HUMICAP has been part of Vaisala’s core business, propelling the company to industry leadership in the field of humidity measurement.

how to choose the Right instrument for measuring humidity and dew point what is humidity?

An introduction to humidity parameters

Learn the basics and get the best out of your humidity measurements.

Humidity measurement and control is called for in a wide variety of industrial applications. Each application has a different set of requirements for humidity instruments, such as required measurement range, tolerance to extreme temperature and pressure conditions, ability to recover from condensation, ability to operate in hazardous environments, and options for installation and calibration. There is no single device that is suitable for all needs. In fact, the range of available equipment is quite large, varying both in cost and quality.

This paper discusses the following topics in order to help in selecting the right humidity instrument:

• Different humidity parameters

• Environmental conditions that influence the choice of humidity instrument

• Sensor properties that influence the choice of humidity instrument

• Practical guidelines for selecting a humidity instrument

partial pressure of water Vapor

Humidity is simply water in its gaseous phase, properly called water vapor. Because water vapor is a gas, most of the common gas laws apply to it, including Dalton's law of partial pressures. Dalton's law says that the total pressure of a gas is equal to the sum of the partial pressures of each of the component gases:

P total

= P

1

+ P

2

+ P

3…

If we consider air, the equation means that the total atmospheric pressure of 1.013 bar (14.7psia) is the sum of the partial pressures of nitrogen, oxygen, water vapor, argon, carbon dioxide, and various other gases in trace amounts.

definition of water Vapor pressure

Water vapor pressure (P w

) is the pressure exerted by the water vapor present in air or a gas. Temperature dictates the maximum partial pressure of water vapor. This maximum pressure is known as saturation vapor pressure (P ws

).

The higher the temperature, the higher the saturation vapor pressure and the more water vapor the air can hold. Thus, warm air has a greater capacity for water vapor than cold air.

If saturation vapor pressure is reached in air or in a gas mixture, the introduction of additional water vapor requires that an equal amount condenses out of the gas as a liquid or a solid. A psychrometric chart shows graphically the relation between saturation vapor pressure and temperature. In addition, vapor pressure tables can be used to see the saturation vapor pressure at any temperature, and there are also a number of computer-based calculation programs available.

effect of pressure on humidity

Dalton's law states that a change in the total pressure of a gas must have an effect on the partial pressures of all of the component gases, including water vapor. If, for example, the total pressure is doubled, the partial pressures of all component gases are doubled as well. In air compressors, a pressure increase "squeezes" water out of the air as it is compressed.

Humidity calculators are also available for mobile phones.

This happens because the partial pressure of water vapor (P w

) is increased, but the saturation vapor pressure is still only a function of temperature. As pressure builds in a receiver tank and P w

reaches P ws

, water condenses into liquid and must ultimately be drained from the tank.

Some humidity measurement instruments allow an individual humidity parameter to be chosen which can then be followed on a graphical display. This picture shows different views of the Vaisala HUMICAP Hand-Held Humidity and Temperature Meter

HM70 display.

Relative humidity

When thinking conceptually of water vapor as a gas, it's easy to define relative humidity. Relative humidity

(RH) can be defined as the ratio of the partial water vapor pressure

(P w

) to the water vapor saturation pressure (P ws temperature:

) at a particular

%RH = 100% × P w

/ P ws

Relative humidity is strongly temperature dependent as the denominator in the definition (P is a function of temperature. For ws

) example, in a room with an RH of 50% and a temperature of 20°C, increasing the temperature of the room to 25°C will decrease the RH to about 37%, even though the partial pressure of the water vapor remains the same.

Pressure will also change relative humidity. For example, if a process is kept at a constant temperature, relative humidity will increase by a factor of two if the process pressure is doubled.

dew point temperature

If a gas is cooled and gaseous water vapor begins to condense in the liquid phase, the temperature at which condensation occurs is defined as the dew point temperature (T d

).

At 100%RH the ambient temperature equals the dew point temperature.

The further negative the dew point is from the ambient temperature, the smaller the risk for condensation and the drier the air.

Dew point directly correlates with saturation vapor pressure (P ws

).

The partial pressure of water vapor associated with any dew point can be easily calculated. Unlike RH, dew point is not temperature dependent but it is affected by pressure.

Typical applications for dew point measurement include various drying processes, dry air applications, and compressed air drying.

Frost point temperature

If the dew point temperature is below freezing – which is the case in dry gas applications – the term frost point (T f is sometimes used to explicitly state

) that the condensing phase is ice. The frost point is always slightly higher than the dew point below 0°C as the water vapor saturation pressure of ice is different to water. People also often refer to dew point for subzero values, even though they mean frost point. Ask for clarification if you are not certain.

parts per million

Unit parts per million (ppm) is sometimes used for low levels of humidity. It is the ratio of water vapor to dry gas or total (moist) gas, and is expressed either by volume/volume

(ppm vol

) or mass/weight (ppm w

Parts per million (ppm vol

).

) can be quantitatively expressed as follows: ppm vol

= [P w

/(P - P ws

)] × 10

6

The ppm parameter is typically used when defining the water vapor content of pressurized and dry pure gases.

7

mixing Ratio

The mixing ratio (x) is the ratio of water vapor mass to the mass of dry gas. It is dimensionless but often expressed in grams per kilogram of dry air. The mixing ratio is mainly used in drying processes and HVAC applications for calculating water content when the mass flow of air is known.

wet bulb temperature

Traditionally, the wet bulb temperature (T w

) is the temperature indicated by a thermometer wrapped in a wet cotton sheath. The wet bulb and ambient temperatures can be used together to calculate relative humidity or dew point. For example, the wet bulb temperature is used in air conditioning applications where it is compared to the dry bulb temperature to determine the cooling capacity of evaporative coolers.

Absolute humidity

Absolute humidity (a) refers to the mass of water in a unit volume of moist air at a given temperature and pressure. It is usually expressed as grams per cubic meter of air.

Absolute humidity is a typical parameter in process control and drying applications.

water Activity

Water activity (aw) is similar to equilibrium relative humidity and uses a scale of 0 to 1, instead of

0% to 100%.

enthalpy

Enthalpy is the amount of energy required to bring a gas to its current state from a dry gas at 0°C. It is used in air conditioning calculations.

the effect of environmental conditions on humidity measurement

Environmental conditions can have a significant effect on humidity and dew point measurements. Take the following environmental factors into consideration to achieve the best possible measurement result:

select a Representative measurement location

Always choose a measuring point that is representative of the environment being measured, avoiding any hot or cold spots. A transmitter mounted near a door, humidifier, heat source, or air conditioning inlet will be subject to rapid humidity changes and may appear unstable.

As relative humidity is strongly temperature dependent, it is very important that the humidity sensor is at the same temperature as the measured air or gas. When comparing the humidity readings of two different instruments, the thermal equilibrium between the units/probes and the measured gas is particularly crucial.

Unlike relative humidity, dew point measurement is independent of temperature. However, when measuring dew point, pressure conditions must be taken into account.

beware of temperature differences

When mounting a humidity probe into a process, avoid temperature drops along the probe body.

When there is a large temperature difference between the probe and the external environment, the whole probe should be mounted within the process and the cable entry point should be insulated.

When there is a risk of condensation, the probe should be mounted horizontally to avoid water dripping down the probe/cable and saturating the filter (see figure 1) .

Ensure that air is allowed to flow around the sensor. Free air flow ensures that the sensor is in equilibrium with the process temperature. At 20°C and 50%RH, 1°C difference between the sensor and the measurement zone will cause an error of 3%RH. At 100%RH the error is

6%RH (see figure 2) .

the Right instrument for high humidity

Environments with >90%RH are defined here as high humidity environments. At 90%RH a difference of 2°C can cause water to condense on the sensor, which in an unventilated space may take hours to dry. Vaisala humidity sensors will recover from condensation.

However, if the condensed water is contaminated, the instrument accuracy can be affected due to deposits on the sensor, especially salt deposits. Even the life of the sensor may be shortened. In applications with high humidity where condensation can occur, a warmed sensor head probe such as the Vaisala HUMICAP

®

Humidity and

Temperature Transmitter HMT337 should be used.

the Right instrument for low humidity

Environments with <10%RH are defined here as low humidity environments. At low humidities, the calibration accuracy of instruments measuring relative humidity may not be adequate. Instead, measuring dew point will provide a good indication of humidity. For example, Vaisala

DRYCAP

®

products are designed for measuring dew point.

If a dryer fails in a compressed air system, water condensation may appear and the instrument will need to recover. Many dew point sensors are damaged or destroyed in such situations, but Vaisala DRYCAP ® dew point sensors withstand high humidity – and even water spikes.

the Right instrument for extreme temperature and pressure conditions

Continuous exposure to extreme temperatures may affect sensor and probe materials over time. It is therefore very important to select a suitable product for demanding environments. In temperatures above

Installation with the ball valve set

Figure 3:

A ball valve installation in a process pipe line.

60°C the transmitter electronics should be mounted outside the process and only a suitable high temperature probe should be inserted into the high temperature environment. Moreover, builtin temperature compensation is required to minimize the errors caused by large temperature swings or operation at temperature extremes.

When measuring humidity in processes operating at around ambient pressure, a small leak may be tolerable and can be reduced by sealing around the probe or cable.

However, when the process needs to be isolated, or when there is a large pressure difference between the process and the external environment, a sealed probe head with appropriate mounting must be used. Pressure leaks at the point of entry will alter the local humidity and result in false readings.

In many applications it is advisable to isolate the probe from the process with a ball valve to enable the removal of the probe for maintenance without shutting down the process

(see figure 3) .

when is a sampling system needed for dew point measurement?

Wherever possible, the probe should be mounted in the actual process to achieve the most accurate measurements and a rapid response time. However, direct installations are not always feasible. In such situations, sample cells installed in-line provide an entry point for a suitable measurement probe.

Note that external sampling systems should not be used to measure relative humidity because the change in temperature will affect the measurement. Sampling systems can instead be used with dew point probes. When measuring dew point, sampling systems are typically used to lower the temperature of the process gas, to protect the probe against particulate contamination, or to enable easy connection and disconnection of the instrument without ramping down the process.

The simplest dew point sampling setup consists of a dew point transmitter connected to a sampling cell. Vaisala has several models suitable for the most common applications and sampling needs.

For example, the easy to install

DSC74 sampling cell is designed for the flow and pressure conditions in compressed air applications.

In demanding process conditions, sampling systems must be designed carefully. As dew point is pressure dependent, a flow meter, pressure gauge, special non-porous tubing, filters, and pump may be needed. As an example, a flow chart showing the

Vaisala DRYCAP

®

Portable Sampling

System DSS70A for DM70 is shown in figure 4 .

9

In a pressurized system a sample pump isn’t needed as the process pressure induces a large enough flow to the sampling cell.

When measuring dew point with a sampling system, trace heating should be used when the ambient temperature around the cooling coil or connecting tube is within

10°C of the dew point temperature.

This prevents condensation in the tubing that connects the dew point instrument to the process.

hazardous environments

Only products with appropriate certification can be used in potentially explosive areas. For example, in Europe products must comply with the ATEX100a directive, which has been mandatory since

2003. Intrinsically safe products are designed in such a manner that even in the event of failure they do not generate enough energy to ignite certain classes of gas. The wiring from the intrinsically safe product into the safe area must be isolated via a safety barrier. For example, the

Vaisala HMT360 series of intrinsically safe humidity transmitters are specially designed for use in hazardous environments.

Vaisala HUMICAP

®

Humidity and Temperature Transmitter Series HMT360 is designed for hazardous and explosive environments.

Figure 4:

The DSS70A sampling system includes a filter to clean the gas and a needle valve to control the sample flow rate. A sample pump is needed to generate flow from an unpressurized process gas.

shock and Vibration

When the probe will be subject to excessive shock or vibration, the choice of probe, mounting method, and installation location needs careful consideration.

what makes a Good humidity sensor?

Humidity sensor performance is a critical contributor to the overall quality of the humidity measurement.

Consider the importance of the following sensor properties:

Fast Response time

The sensor response time is the speed of response when the sensor is subjected to a step change in humidity. In addition to the sensor, factors such as temperature, airflow, and filter type all have an effect on response time. A blocked filter will give a slower response.

optimal measurement

Range

The choice of humidity sensor depends on the application and operating temperature, especially at the extremes of humidity.

The majority of Vaisala's humidity sensors work over the full range from 0 to 100%RH. Vaisala HUMICAP

® sensors are the optimal choice for applications with a relative humidity around 10–100%RH, whereas

DRYCAP

®

sensors are designed for measurements in low humidities around 0–10%RH.

Good chemical tolerance

Aggressive chemicals can damage or contaminate sensors. The instrument manufacturer should know the effects of various chemicals on their sensors and be able to give advice related to acceptable chemical concentrations.

high Accuracy

Accuracy as a term is well established, but difficult to define.

Each step in the calibration chain

– from the primary standard in an internationally recognized calibration laboratory, to the actual product

10

manufacture and the measurement on site – introduces measurement error. The sum of these potential errors is the uncertainty of the measurement.

When selecting a humidity sensor, consider the following factors associated with accuracy:

• Linearity over the working range

• Hysteresis and repeatability

• Stability over a period of time

• Temperature dependence of the sensor

During manufacture, Vaisala products are compared and adjusted against factory standards that are

Humidity sensors from Vaisala.

directly traceable to internationally recognized standards. The calibration chain is detailed in the certificates that are supplied with the majority of Vaisala products.

the Right humidity instrument for the Job

Protective filters for Vaisala’s humidity instruments.

No matter what the application, the total range of gas temperatures and expected water vapor levels must be known in order to decide the optimal humidity parameters and the optimal instrument for the environment.

The process pressure must also be known when measuring humidity within the process. In addition, it must be decided whether to make the measurement at the process pressure or at some other pressure. For gases other than air, the gas composition must be known.

The terms probe, transmitter, and sensor describe products that measure humidity. The probe is the part of the product that contains the humidity sensor. The probe may be rigidly bound to the transmitter or connected with a flexible cable.

The transmitter provides the output signal.

Vaisala designs and manufactures a range of products for measuring relative humidity, temperature, and dew point based on HUMICAP

® and DRYCAP ® sensors. All Vaisala humidity instruments feature built-in temperature compensation to minimize the errors caused by temperature variations and operation at extremes of temperature. Many of the products include built-in calculations for other humidity parameters.

protect the sensor and electronics with the Right Filter

As well as screening the sensor from any stray electromagnetic fields, the filter protects the sensor from dust, dirt, and mechanical stress.

A membrane or netting filter is a good alternative for the majority of applications. In temperatures above

80°C, in high pressure, or in rapidly moving air up to 75 m/sec, a sintered filter should be used.

A suitable protective enclosure protects the instrument electronics from dust, dirt, and excessive humidity. An enclosure with an IP65 or NEMA 4 classification gives good protection against dust and sprayed water. The cable entry points need to be sealed during installation.

When using the instrument outside, it should be mounted in a radiation shield or Stevenson screen to prevent solar radiation or extremes of weather from affecting the measurement.

must the instrument tolerate condensation?

Making good quality humidity measurements in near-condensing conditions is very challenging.

Warmed probe technology ensures reliable measurements when measuring relative humidity close to saturation point. The humidity level of the warmed probe always stays below the ambient level, where condensation occurs.

must the instrument withstand exposure to chemicals?

A chemical purge feature helps to maintain measurement accuracy in environments with a high concentration of chemicals or

11

cleaning agents. The chemical purge heats the sensor at regular intervals to remove chemicals that may have accumulated over time.

the importance of electromagnetic compatibility (emc)

There are many standards defining the ability of products to withstand external electrical interference.

In addition, the product must not generate emissions that can cause interference to sensitive equipment.

Industrial applications have more demanding EMC requirements than HVAC installations – the CE marking used in Europe guarantees compliance.

consider wiring and earthing

Except for short cable runs, a screened cable is recommended.

Proximity to high-voltage cables or

RF sources should be avoided. It is good practice to earth the connection cable screen at a common point and avoid multiple earth points. Galvanic isolation is also available on some

Vaisala products.

which power supply and output signals are needed?

The majority of measurement instruments are powered using a low voltage supply. If a low voltage AC supply is used, an isolated supply is recommended for each transmitter to avoid earth loops or interference from an inductive load.

Analog output instruments usually have an option for both voltage and current outputs. The choice depends on the length of the signal path and on the interfacing equipment. Some products have a 4–20mA loop power connection, which is a 2-wire system where the output signal current is measured in the supply line.

In addition to analog outputs, some

Vaisala products feature digital communication via RS-232, RS-485, or LAN/WLAN interfaces. Selected commercial protocols (Modbus,

BACnet) are also available.

consider calibration before purchasing

Instruments typically need to be calibrated every year or every second year. Calibration requirements depend on the application and the stability of the instrument, with wide variations in how easy it is to carry out field checking and calibration.

Some instruments need to be sent to a laboratory for calibration, for example. Understanding the calibration needs is therefore an important part of instrument selection.

calibration Frequency

An individual calibration certificate for a particular instrument indicates the accuracy and linearity at the time of calibration. However, it does not reflect the stability of the instrument in the long run. Calibration at routine intervals is essential to understand the instrument’s long-term stability.

Calibration frequency depends on the operating environment. A rule of thumb for Vaisala instruments is that yearly calibration is enough for HUMICAP

®

products, whereas in most applications a two-year calibration interval is suitable for

DRYCAP

®

products. When measuring in constant high humidity (>85%RH), high temperature (>120°C), or chemically aggressive atmospheres, more frequent checks may be needed.

12

On-site calibration of a HMW90 humidity transmitter with a HM70 hand-held meter.

humidity instrument calibration

In calibration, the humidity reading of an instrument is compared against a portable reference. The reference should be regularly calibrated and provided with a valid certificate.

When selecting one of the many calibration methods, time, cost, technical requirements, expertise, and the unique needs of the organization must be balanced.

Portable meters and products that can be removed from the installation can be calibrated in an approved laboratory or returned to the instrument provider for calibration.

Vaisala has four Service Centers around the world available for calibration.

Instruments installed in processes that operate within narrow boundaries can be calibrated using on-site one-point calibration that can be performed without disconnecting the instrument. One-point calibration can also be used to identify the need for further calibration and adjustment.

Some portables such as the Vaisala

HUMICAP

®

Hand-Held Humidity and Temperature Meter HM70 or the Vaisala DRYCAP

®

Hand-Held

Dewpoint Meter DM70 can be directly connected to the installed product and the readings compared to those on the portable meter’s display.

In environments with large variations in humidity, multi-point calibration is recommended. Twopoint or three-point calibrations

Vaisala Humidity Calibrator HMK15 for multi-point on-site calibrations.

can be accomplished in the field with the help of humiditygenerating equipment, as long as the local environment is at a stable temperature. The advantage of multipoint calibration compared to onepoint calibration is higher accuracy over the entire measurement range.

Multiple humidity levels can be created with the Vaisala Humidity

Calibrator HMK15, for example.

calibration of dew point instruments

It is a demanding task to perform high-quality calibrations on low dew point instruments. For this reason, Vaisala doesn't recommend customers perform calibrations on Vaisala DRYCAP

®

products.

Instead, they should be calibrated in professional calibration laboratories, such as Vaisala Service Centers.

However, it is possible to perform a field check on a dew point instrument to identify whether adjustment is needed, using the Vaisala DRYCAP

true humidity Readings in condensation conditions

Vaisala’s unique warmed probe provides fast and reliable measurement in environments where humidity is near saturation. The heating prevents condensation from forming on the sensor.

As the probe is heated, the humidity level inside it stays below the ambient level. With accurate temperature measurement, the ambient dew point can be calculated precisely.

If the relative humidity value is needed, an additional temperature sensor is used. The measured ambient temperature provides the compensation for calculating relative humidity and other humidity parameters.

hmw90 series humidity and temperature transmitters for high performance hVAc Applications

The HMW90 Series Humidity and Temperature Transmitters are designed for demanding HVAC applications.

Wall-mounted Vaisala HMW90

Series HUMICAP ® Humidity and

Temperature Transmitters measure relative humidity and temperature in indoor HVAC applications, where high accuracy, stability, and reliable operation are required.

The flexible HMW90 series offers a variety of options and features.

Transmitters include a display and a sliding cover with either an opening for the display or a solid front. Both analog and digital output options, including special scalings and calculated parameters, are available.

Quick and easy to install

HMW90 series transmitters are quick and easy to install. The wiring is connected through the back plate and the electronics with the sensors can be snapped on easily after the wiring is complete. The transmitter is configured using dip switches, which are accessible when the enclosure is open.

digital communication brings benefits

The introduction of digital (BACnet/

Modbus) communication to field level devices brings many advantages. For example, all sensors can be centrally accessed and their performance can be easily monitored. Wiring is simple when multiple sensors are installed on the same bus. Sensors can be set up using standardized tools, and the system can be enlarged with additional sensors quickly and conveniently.

The Vaisala HUMICAP ® Hand-Held

Humidity and Temperature Meter

HM70 is designed for demanding humidity measurements in spotchecking applications. It is also ideal for field checking and calibration of

Vaisala's fixed humidity instruments.

The HM70 incorporates the latest generation of the Vaisala HUMICAP

®

Sensor. It is reliable and has better than ever long-term stability.

Additionally, it has a sensor that copes well with chemical interference and provides accuracy that lasts in demanding conditions.

The chemical purge option maintains measurement accuracy in environments with high concentrations of chemicals. The sensor preheat option reduces measurement delays as it keeps the sensor dry when the probe is inserted into hot and humid processes.

three probes to choose from

The HMP75 is a general purpose probe whereas the HMP76 is a long, stainless steel probe especially suitable for spot-checking in ducts.

The HMP77 is a small probe at the end of a 5-meter cable. The probe is ideal for difficult-to-reach areas and for on-site calibration of Vaisala's process transmitters.

In addition, the HM70 supports the use of Vaisala's dew point, carbon dioxide and moisture in oil probes, allowing measurements in several multiparameter applications.

Vaisala humicAp® humidity and temperature probe hmp42

The HMP42 probe can be used for spot checking humidity and temperature in applications which require an extremely thin probe. Typically the probe is used for monitoring the drying of structures during construction or after water damage. It is ideal to be used when measuring in any tight places, in ducts or chambers or, for example, under a linoleum floor.

The probe diameter is only 4 mm, allowing access into very small, tight, and hard-to-reach spaces.

Vaisala humicAp® humidity and temperature probe hmp46

Typical applications for the HMP46 are plant maintenance, installation and inspection of air conditioning systems, production and storage areas and production processes. The HMP46 operates in full humidity range of

0 ... 100 %RH. The temperature range is from -40 to +100 °C (-40 ... +212 °F).

For short periods of time, the probe can withstand temperatures up to

+180 °C (+356 °F).

The HMP46 probe is solid and rugged. Its stainless steel probe is made to withstand rough handling in mechanically demanding applications.

The probe’s long shaft can also reach otherwise unreachable places.

high performance sensor

The HMP42/46 probes incorporate

Vaisala HUMICAP ® Sensor. This sensor has high accuracy, excellent long-term stability and negligible hysteresis.

In addition, the sensor is insensitive to dust, particulate dirt and most chemicals.

A borehole in concrete and a measurement probe HMP40S inserted in it.

Vaisala HUMICAP

®

Structural Humidity Measurement Kit SHM40 offers an easy and reliable solution for humidity measurements in concrete and other structures.

Concrete dries unevenly and is usually drier on the surface, consequently it is important to measure beneath the surface conditions. The borehole method provides information about the humidity profile under the surface. In this method, a humidity probe is left in the borehole until the humidity in the hole has reached an equilibrium state and the stabilized values can be read.

shm40 is All you need for borehole humidity measurement

The Vaisala HUMICAP

®

Structural

Humidity Measurement Kit SHM40 is an ideal solution for the borehole method. The starter kit is comprised of an HMP40S probe, HM40 indicator and accessories for the borehole method in a weather-proof case, optimized for use in harsh and humid construction sites.

Additional accessories for the SHM40 can be used to prepare a moisture measurement hole in fresh concrete.

Pre-formed holes eliminate the need for drilling and the risk of damaging heating elements or tubing embedded in the concrete.

easy measurement with multiple hmp40s probes and Quick connectors

HMP40S measurement probes are interchangeable. The probes connect easily to the HM40 indicator with a snap-on connector enabling convenient use of multiple probes with one indicator. The measurement data can be displayed in numeric, statistic or graph views.

Vaisala Service Centers offer accredited calibrations for humidity, temperature and barometric pressure.

No measuring instrument stays accurate by itself. It is essential that the functioning of an instrument is periodically checked against a reference. Vaisala has developed the

Vaisala Humidity Calibrator HMK15 to make calibration and spot checking of humidity probes and transmitters easy and reliable.

method used by leading laboratories

The operating principle of the

HMK15 is based on the fact that a saturated salt solution generates a certain relative humidity in the air above it. The reading of the humidity probe or transmitter can then be adjusted accordingly. Many leading laboratories use this generally accepted and reliable method to calibrate humidity instruments.

Usually two or three different salt solutions are used. Salts are chosen according to the application.

certified salts

The HMK15 can be ordered with certified and pre-measured salts.

A sample calibration is made from each batch in Vaisala’s Measurement

Standards Laboratory (MSL).

calibrated thermometer

The HMK15 can be ordered with a thermometer, which is used for measuring the temperature during the calibration. It can also be used for checking the temperature measurement accuracy of the transmitter. The thermometer can contain either mercury (accuracy

±0.3 °C (±0.54 °F)) or red capillary fluid (accuracy ±1.0 °C (±1.8 °F)).

The Vaisala HUMICAP

®

Humidity and

Temperature Probe HMP155 provides reliable humidity and temperature measurement. It is designed especially for demanding outdoor applications.

long-term stability

The HMP155 has the proven Vaisala

HUMICAP

®

180R sensor that has excellent stability and withstands well harsh environments. The probe structure is solid and the sensor is protected by default with a sintered teflon filter, which gives maximum protection against liquid water, dust, and dirt.

warmed probe and high humidity environment

Measuring humidity reliably is challenging in environments where humidity is near saturation.

Measurements may be corrupted by fog, mist, rain, and heavy dew. A wet probe may not give an accurate measurement in the ambient air.

72

This is an environment to which

Vaisala has designed a patented, warmed probe for reliable measuring.

As the sensor head is warmed continuously, the humidity level inside it stays below the ambient level. Thus, it also reduces the risk of condensation forming on the probe.

Fast measurements

With its fast response time, the additional temperature probe for the

HMP155 is ideal for measurement in environments with changing temperatures. The new membrane filter speeds up the RH measurement.

true humidity Readings in condensing conditions

In weather observations dew formation makes reliable humidity measurement difficult. When dew has formed on the humidity sensor, it is impossible to obtain a true reading until this dew evaporates.

Both the PTU307 and HMT337 avoid this problem by warming the probe.

When warmed, the relative humidity inside the probe stays below the ambient level. With an accurate temperature measurement, the ambient dew point can be calculated precisely. To obtain the ambient relative humidity, an additional probe measures the ambient temperature,

After a period of 100 % relative humidity, the warmed probe measures the true humidity, whereas the non-warmed probe takes time to recover from the condensation.

and the transmitter calculates the relative humidity from the dew point and temperature values.

open shield prevents microclimates

The warmed probe of the HMT337/

PTU307 is mounted in a shield which is open at the bottom to ensure steady air circulation to the sensor even in calm weather.

In traditional radiation shields sleet or snow can accumulate on the shield and prevent the proper air circulation through the shield, and create a humid microclimate until the snow melts.

essential for critical weather measurements

Obtaining a true humidity reading is particularly important e.g. in traffic safety: at airports and at sea as well as on the roads. It is essential, for example, in fog and frost prediction.

For calibration, a portable HMP77 reference probe is easy to attach beside the HMT337 or PTU307 probe.

dew point


Vaisala dRycAp® sensor for measuring dew point

In 1997 Vaisala introduced DRYCAP

®

, a new type of dew point sensor based on thin-film polymer technology. Since its launch, the DRYCAP product family has grown to encompass a huge range of applications, from drying processes to compressed air and dry chambers. The DRYCAP sensor is particularly renowned for its reliable performance in hot and very dry environments.

how it works

DRYCAP’s unrivalled performance is based on two innovations: the proven capacitive thin-film polymer sensor and the auto-calibration function.

The sensor’s thin-film polymer absorbs or releases water vapor as the surrounding humidity increases or decreases. The dielectric properties of the polymer change as the humidity around the sensor changes, as does the capacitance of the sensor. Capacitance is converted into a humidity reading. The capacitive polymer sensor is bonded together with a temperature sensor, and dew point is calculated from the humidity and temperature readings.

Vaisala’s patented auto-calibration function optimizes the measurement stability at low dew points.

The sensor is heated at regular intervals during the automated auto-calibration procedure. The humidity and temperature readings are monitored as the sensor cools to ambient temperature, with offset correction compensating for any potential drift. This enables the

DRYCAP sensor to deliver accurate measurements in the long term, dramatically reducing the need for maintenance.

typical Applications for dew point measurement

Vaisala DRYCAP dew point instruments measure dew point in industrial applications, where gas humidity is typically very low. Dew point is often a critical parameter, with inadequate control resulting in problems such as process downtime, damaged process equipment, and deterioration in end-product quality.

Dew point is measured in various drying and heat-treatment processes.

It is also controlled in compressed air, where excess moisture can result in poor end-product quality, ice formation, and equipment corrosion.

Structure of the DRYCAP sensor.

DRYCAP sensor.

The DRYCAP story began in the mid-1990s following an unresolved measurement challenge. Traditional humidity instruments were not accurate enough at very low humidities, while commonly used aluminum oxide sensors were prone to drift and required frequent calibration.

There was strong demand for accurate, easy-to-use, costeffective, and low-maintenance dew point instruments.

The DRYCAP Story

Vaisala's solution was to combine the highest quality polymer technology with a patented key feature – auto-calibration – that would eliminate sensor drift in very dry conditions. The result was the stable, reliable, and accurate DRYCAP sensor.

The first DRYCAP products were launched in 1997, and this highly successful innovation is still going strong today.

DRYCAP also led the way for the next great innovation: the world’s first transmitter that monitors both dew point and process pressure simultaneously, aimed at compressed air customers worldwide. The story continues.

stability at low dew points

The Vaisala DRYCAP

®

sensor is immune to particulate contamination, water condensation, oil vapor, and most chemicals. Since the sensor is condensation-resistant, its performance is unmatched in low dew point applications where water spikes occur in the process. The sensor recovers rapidly from contact with free water.

unique Auto-calibration

Feature

The stability of the DMT340 series is due to its unique auto-calibration function, developed by Vaisala. This feature allows the transmitter to perform calibration and adjustment by itself while the measured process is running. If the measurement accuracy is not confirmed, corrections are made automatically. The procedure is so quick and corrections so minor that it causes no disruption, ensuring easy maintenance and high performance. To maintain high performance, transmitters can be sent to Vaisala for calibration. Calibration intervals depend on the application; in normal conditions it is recommended to have calibration performed every two years.


The DMT340 features a large numerical and graphical display with a multilingual menu and keypad.


The optional data logger, with real-time clock, makes it possible to generate over four years of measurement history and zoom in on any desired time or time frame.

The display alarm allows tracking of any measured parameter, with freely configurable low and high limits.


The DMT340 can support up to three analog outputs; an isolated galvanic power supply and relay outputs are also available.

Dewpoint Transmitters DMT345 and DMT346 are designed to measure and control humidity, especially in dry environments with high temperatures.

The Vaisala DRYCAP

®

Dewpoint

Transmitters DMT345 and

DMT346 are designed for humidity measurement in industrial drying applications with particularly high temperatures.

Both transmitters incorporate the

Vaisala DRYCAP ® sensor, which is accurate, reliable, and stable. The sensor is condensation-resistant and is immune to particulate contamination, oil vapor, and most chemicals. The DRYCAP ® sensor is notable for its swift response time and rapid recovery after getting wet.

measure humidity directly in hot processes

The DMT345 and DMT346 are built for direct measurement in hot processes. Therefore, there is no need for sampling systems and trace heating. As a result, high measurement accuracy and constancy are maintained.

88

The accuracy and stability of the

DMT345 and the DMT346 are due to their unique auto-calibration function, developed by Vaisala. This feature allows the transmitter to perform calibration and adjustment by itself while the measured process is running. If the measurement accuracy is not confirmed, corrections are made automatically. The procedure is so quick and corrections so minor that it causes no disruption, ensuring easy maintenance and high performance. In normal conditions, it is recommended to have a traceable calibration performed once a year.

dmt345: Accurate in hot and dry environments

The DMT345 is designed for accurate humidity measurement in hot and dry conditions. This model provides unmatched dry-end measurement accuracy at temperatures up to 140 °C; however, it can operate safely at temperatures up to 180 °C.

The stainless steel probe is especially designed for high temperatures and has an optional installation flange for easy adjustment of the probe’s installation depth and, therefore, more precise positioning.

dmt346: Reliable in Very hot processes

The DMT346 provides the best measurement performance at process temperatures between 140 °C and 350 °C.

The DMT346 includes a cooling set as standard. The cooling effect can be regulated by adding the cooling fins, or they can be removed from the set for optimal measurement performance.

The cooling system has no moving parts, and requires no additional power or cooling utilities, so there is no risk of sensor damage due to mechanical cooling failure.

Additionally, sensor warming minimizes the risk of condensation accumulating on the sensor. In low humidity conditions the combination of auto-calibration and

DRYCAP

®

ensures accurate measurement.


The DMT345 and DMT346 transmitters feature a large numerical and graphical display with a multilingual menu and keypad. It allows users to easily monitor operational data, measurement trends, and access measurement history for the past 12 months.

Due to its wide measurement range and high long-term stability, the DMT242 is an ideal choice for low dew point industrial applications such as compressed air dryers, plastic dryers and other OEM applications.

Vaisala dRycAp

®

The Vaisala DRYCAP ® Dewpoint

Transmitter DMT242 provides reliable and stable measurements for industrial dryer applications. It is designed for extreme conditions.

DMT242 incorporates the Vaisala

DRYCAP

®

thin film polymer sensor and auto-calibration software.

The standard sensor choice for dry gases and desiccant dryers is

DRYCAP

®

180M and for more humid applications such as refrigeration dryers, a DRYCAP

dss70A portable sampling system and sampling cells for dm70

www.vaisala.com

The DSS70A provides a compact solution for field checking dew point where direct measurement is difficult. Typical applications for the sampling system are metal treatment and plastics drying processes.

dss70A portable sampling system

The DSS70A is designed to provide dew point sampling flexibility for the

DM70 hand-held dew point meter. For processes at atmospheric pressure, a battery powered pump is used to extract a gas sample. For pressurized processes up to 20 bar, the sample is measured at process pressure and then reduced to atmospheric pressure for venting or re-direction, bypassing the pump. In all cases, the sample gas passes through a filter to remove particulate contamination before measurement. Flow through the system is controlled and monitored with a needle valve and flow meter.

The DSS70A is easily connected to an appropriate sample point with tubing (typically 1/4” or 6 mm).

The measured dew point must be below ambient temperature to avoid condensation in the system. Gas temperatures higher than +40 °C

102

(+104 °F) should be cooled with a short PTFE (included in the DSS70A system) or stainless steel tube prior to entering the DSS70A. DSS70A is an accessory for DM70 Dewpoint Handheld Meter.

sampling cells for pressurized processes

The DM70 can easily be connected to pressurized processes. In addition to direct pipeline installation, a variety of sampling cell options are available for gas sampling.

The DSC74 sampling cell is the recommended choice. It has a variety of connection adapters that allow several different ways of installation.

The quick connector with a leak screw allows a very fast connection for compressed air lines. Additionally, two thread adapters are available for the inlet port.

The DSC74B is a two-pressure sampling cell, which enables measurements in both process and ambient pressure. This sampling cell is especially suitable for dew point measurements in SF

The Vaisala Multiparameter Transmitter DPT145 with the DILO DN20 connector.

The Vaisala Multiparameter

Transmitter DPT145 for SF6 Gas is a unique innovation that enables online measurement of dew point, pressure, and temperature. It also calculates four other values, including SF6 density.

The DPT145 is especially well suited for integration into OEM systems.

online Reliability

Online dew point measurement combined with pressure measurement provides an excellent assessment of the condition of the

SF6 insulation. Sudden and minor leakages are immediately detected by the direct normalized pressure measurement, while online dew point measurement alerts the user to moisture issues, which can weaken the insulation properties of SF6 and cause rapid deterioration. With the DPT145, it is also easy to build a redundant solution for multiple parameters.

savings Across the board

A single transmitter, instead of several, saves time and money across the board, from investment to installation, operation and servicing. Lower assembly costs, fewer cables and connectors, minimized need for on-site visits and field operations - all these translate into cumulative savings.

The long calibration interval results in further savings.

Risk-Free, Greener solution

Online measurement enables gas trends to be followed via a data collection system, making monitoring fast, risk-free, and accurate. Using one instrument for monitoring seven different parameters means also fewer mechanical connections and

106 reduces the risk of leaks. Monitoring is environmentally friendly because there is no need for sampling - no SF6 gas is released into the atmosphere.

the Fruit of experience

Vaisala has over 70 years of extensive measurement experience and knowledge. The DPT145 brings together the proven DRYCAP

moisture in oil


Vaisala humicAp® sensor for measuring moisture in oil

Water is a common contaminant in industrial oils. Water contamination deteriorates the performance of the oil, be it used for lubrication, cooling, insulation or other purposes. High moisture content increases the risk of corrosion, overheating, machine malfunction and other problems and can ultimately lead to costly failure and unscheduled downtime.

Monitoring the oil for moisture is a simple way of improving the reliability of industrial machinery and equipment. With time, substantial savings in maintenance costs can be achieved.

Free water Formation – the critical point

Water can dissolve in oil. When the water content of the oil increases, it eventually reaches the saturation point of the oil. Once the fluid has reached its saturation point, any additional water introduced will separate out as free water by forming a distinct layer. Alternatively, the oil can form dispersion with water, which turns the oil cloudy. Since most oils are less dense than water, the water layer will usually settle below the oil with time.

Free water formation is critical in terms of problems related to water in oil. When water is no longer dissolved in the oil, corrosion and wearing of equipment increase rapidly.

Therefore it is important to keep the moisture content safely below the saturation point.

The ability of oil to hold dissolved water depends on the type and age of the oil as well as its additives.

Two major factors have an effect on the saturation point as the oil ages: temperature fluctuations and changes in the chemical make-up due to the formation of new substances as by-products of the chemical reactions.

water Activity (a oil Quality

w

) – a direct measure of

The conventional measure for water content in oil is ppm (parts per million), which describes the absolute amount of water in the oil.

Ppm measurement has, however, a major limitation. It does not account for any variations in the oil’s saturation point. In other words, ppm measurement provides no indication

Unique Benefits of HUMICAP in Oil Moisture Measurements

▪

Fast. Online, real-time detection of moisture in oil without sampling

▪

Reliable. Tells the true margin to water saturation point in all changing conditions, taking into account e.g. temperature changes and aging of oil

▪

Highly stable. Excellent pressure and temperature tolerance

▪

Easy to install through ball valve – no need to shut down the process

▪

Enables predictive maintenance work. Trends can be quickly identified.

of how close the moisture level is to the saturation point in a dynamic system with fluctuating saturation point. By measuring water activity instead of ppm, the risk of actually exceeding the saturation point can be avoided.

110

Water activity measurement indicates directly whether there is a risk of free water formation. With a relative scale from 0 (no water present) to 1 (the oil is saturated with water) it gives a reliable indication of how close the saturation point of water is.

In contrast to traditional measurement techniques, water activity measurement is independent of oil type. Regardless of the saturation point of the fluid, water activity measurement always provides a true indication for the risk of free water formation, even when the saturation point is increasing or decreasing. In its simplicity, water activity value is understandable at a glance. Trends can be quickly identified.

Vaisala humicAp® for measuring water Activity

The Vaisala transmitters used for measuring moisture in oil feature the HUMICAP

®

sensor, a capacitive thin-film polymer sensor especially developed for demanding moisture measurements in liquid hydrocarbons.

The HUMICAP sensor consists of four functional layers: glass substrate, lower electrode, water-active polymer layer, and porous upper electrode.

The thin-film polymer either absorbs or releases water as the surrounding moisture level changes.

Water molecules move to/from the polymer layer until there is moisture equilibrium between the polymer and the oil. The dielectric properties of the polymer depend on the moisture level. As the moisture level changes, the dielectric properties of the polymer film change, and so does the capacitance of the sensor. The instrument’s electronics measure the capacitance of the sensor and convert it into water activity.

Oil molecules or additives do not penetrate the electrode. Thus the sensor output is independent of the oil type.

on-line measurement

On-line water activity measurement ensures reliable performance of equipment at all times. Timeconsuming sampling and laboratory analysis are no longer needed. This not only reduces the risk of human induced error but also provides cost savings in equipment and chemicals.

typical Applications for moisture in oil measurement

Moisture is an important factor determining the condition of both lubricating and transformer oils.

With on-line information on the quality of the oil, preventive actions can be taken and the maintenance costs cut substantially.

carbon dioxide


Vaisala cARbocAp® sensor for measuring carbon dioxide

First launched in 1997, the Vaisala CARBOCAP

®

carbon dioxide (CO

2

) sensor features a groundbreaking innovation

– the micromachined, electrically tunable Fabry-Perot

Interferometer (FPI) filter for built-in reference measurement.

This reliable and stable sensor has been delivering accurate

CO

2

measurements for over 15 years across a wide range of industries and applications, from building automation and safety to life sciences and ecological research.

how it works

Carbon dioxide has a characteristic absorbance band in the infrared (IR) region at a wavelength of 4.26 µm.

This means that when IR radiation is passed through a gas containing

CO

2

, part of the radiation is absorbed.

Therefore, the amount of radiation passing through the gas depends on the amount of CO

2

present, and this can be detected with an IR detector.

The Vaisala CARBOCAP sensor features an electrically tunable

FPI filter located in front of the IR detector. In addition to measuring

CO

2

absorption, the micromechanical

FPI filter enables a reference measurement at a wavelength where no absorption occurs. When taking the reference measurement, the

FPI filter is electrically adjusted to switch the bypass band from the absorption wavelength to a non-

122 absorption wavelength. The reference measurement compensates for any potential changes in the light source intensity, as well as for contamination and dirt accumulation in the optical path. This feature means that

CARBOCAP sensor operation is highly stable over time.

Instruments measuring at both the absorption and the reference wavelength with a single light source are known as single-beam dual-wavelength instruments.

The technology is widely applied in costly analyzers. The unique feature of the CARBOCAP sensor is its micromachined FPI filter, which performs a dual-wavelength measurement using a single detector.

The compact size of the sensor means that this advanced technology can be incorporated into small probes, modules, and transmitters.

typical Applications for carbon dioxide measurement

Vaisala CARBOCAP instruments are well suited to a wide range of applications, from ppm (parts per million) to percentage-level CO

2 measurements. Since CO

2

is harmful in high concentrations, it is present at percentage levels only within closed processes such as fermentation and controlled-atmosphere storage environments. Percentage-level measurements are also typical in life-science applications such as CO

2 incubation.

Normal atmospheric air includes CO

2 at ppm levels. Typical CARBOCAP applications include ventilation control in buildings occupied by people, animal shelters, and greenhouses. In areas where large volumes of CO

2

CO

2

are handled, reliable

measurement with alarm control is an important safety precaution.

The CARBOCAP sensor is also a popular choice in ecological measurement applications, where excellent long-term stability and tolerance to harsh conditions are important requirements.

Fabry-Perot

Interferometer Filter

Detector

The CARBOCAP story began in 1992, when micromechanical sensors were being intensively researched at Vaisala. The groundbreaking idea of miniaturizing the Fabry-Perot

Interferometer (FPI) was born, leading to collaborative development work with VTT

Technical Research Center of

Finland. Later, a patent application was submitted for a single-channel gas concentration measurement method using the FPI.

The CARBOCAP® Story

The driving force behind the innovation of the CARBOCAP sensor was Vaisala's commitment to developing superior technologies for environmental measurements. And indeed,

Vaisala’s pioneering work in the field of silicon-based NDIR technology and electrically tunable filters resulted in the compact, simple and high-performance

CARBOCAP sensor. To this day, the long-term stability and reliability of the measurement provided by the

FPI is unrivaled.

The first commercial CARBOCAP products for measuring ppm-level

CO

2

in ventilation applications were launched in 1997, with instruments for percentage-level

CO

2

measurements following soon after. CARBOCAP technology is proven in a wide range of applications, including ecological measurements, where it performs reliably in harsh environments such as soil and snow, satisfying the thirst for knowledge that scientists have for understanding nature’s processes.

The wall-mounted Vaisala

CARBOCAP ® Carbon Dioxide

Transmitter GMW115 is a compact transmitter for measuring room carbon dioxide levels in building automation applications.

Room carbon dioxide level is an indicator for indoor air quality and human presence. It can be used to steer ventilation to introduce an adequate (but not excess) air flow based on the true need for fresh air.

Demand controlled ventilation is well suited to buildings and premises where occupancy varies. Examples of such facilities are schools, offices, meeting rooms, auditoriums, and sports arenas.

The GMW115 transmitter is designed for indoor use in various demand controlled applications. The transmitter is easy to install and needs practically no maintenance.

There are two optional ranges of

0…2 000 ppm and 0…5 000 ppm to select from.

proven performance with the Vaisala cARbocAp® sensor

The GMW115 transmitter uses Vaisala

CARBOCAP

®

carbon dioxide sensor, a silicon-based infrared (IR) absorption sensor. The excellent long-term stability of the CARBOCAP

®

sensor results from its unique measurement technology. The sensor features an electrically tunable Fabry-Perot

Interferometer for built-in reference measurement. The sensor not only measures CO

2

absorption but also a reference, which makes it possible to compensate for potential light intensity variations and contamination and dirt accumulation in the optical path, making the sensor extremely stable over time.

CARBOCAP sensor has no need for any compensation algorithms that are used in more simple sensors to compensate for their drift. In buildings with around-theclock occupancy (e.g. hospitals, manufacturing facilities, residential buildings, and retirement homes) the compensations based on assumed background carbon dioxide level simply do not work.

The GMD/W20 series transmitters can be used independently, or incorporated into building energy management systems. The series consists of duct mount units

GMD20/D and wall mount units

GMW21/D and GMW22/D. Version D has a display. The two sizes in the wall-mount series make them easy to install for most standard junction boxes.

The duct units' compact sensor head design requires only a small hole in a ventilation duct, thereby minimizing the risk of leaking gaskets and measurement errors.

In addition to the standard

0 ... 20 mA, 4 ... 20 mA and 0 ... 10 V outputs, there are three other options: two LonWorks

®

interfaces and a relay output. The relay output is standard with the display units.

improve indoor Air at minimal energy costs

The use of the GMD/W20 series transmitters ensures the best possible control of air quality and results in considerable savings in energy consumption, maintenance and recalibration costs.

temperature option

The GMA20T temperature module, an option with the GMW21 wall mount unit, combines both CO

2

and temperature measurement into one transmitter. The GMA20T has an output of 0 ... 10 V corresponding to a temperature range of 0 ... +50 °C

(+32 ... +122 °F).

carbon dioxide sensor, a silicon-based infrared (IR) absorption sensor. The excellent long-term stability of the CARBOCAP® sensor results from its unique measurement technology. The sensor features an electrically tunable Fabry-Perot

Interferometer for built-in reference measurement. The sensor not only measures CO2 absorption but also a reference, which makes it possible to compensate for potential light intensity variations and contamination and dirt accumulation in the optical path, making the sensor extremely stable over time.

CARBOCAP sensor has no need for any compensation algorithms that are used in more simple sensors to compensate for their drift. In applications with constant elevated levels of carbon dioxide and in buildings with around-theclock occupancy (e.g. hospitals, manufacturing facilities, residential buildings, and retirement homes) the compensations based on assumed background carbon dioxide level simply do not work.

Vaisala bARocAp® sensor for measuring pressure

First introduced in 1985, Vaisala BAROCAP

®

is a silicon-based micromechanical pressure sensor that offers reliable performance in a wide variety of applications, from meteorology to industrial measurements. Combining two powerful technologies – single-crystal silicon material and capacitive measurement – BAROCAP sensors feature low hysteresis combined with excellent accuracy and long-term stability.

how it works

BAROCAP is a micromechanical sensor that uses dimensional changes in its silicon membrane to measure pressure. As the surrounding pressure increases or decreases, the membrane bends, thereby increasing or decreasing the height of the vacuum gap inside the sensor. The opposite sides of the vacuum gap act as electrodes, and as the distance between the two electrodes changes, the sensor capacitance changes.

The capacitance is measured and converted into a pressure reading.

The BAROCAP sensor’s properties

– good elasticity, low hysteresis, excellent repeatability, low temperature dependence, and superior long-term stability – are the result of its single-crystal silicon material. The capacitive structure gives the sensor its wide dynamic range and provides a built-in mechanism for overpressure blocking.

typical Applications for barometric pressure measurement

Barometric pressure measurement has a wide variety of applications within meteorology. Pressure data is required for estimating the amount of precipitable water vapor in the atmosphere. Typical applications include weather stations, data buoys,

GPS meteorology, and environmental data logging. Barometric pressure measurement is also used in hydrology and agrology applications.

Barometric pressure data is also required in several industrial applications. It is measured in pressuresensitive industrial equipment, such as laser interferometers and lithography systems, aviation applications, and in exhaust-gas analysis. Metrological applications include laboratory pressure standard measurements and environmental monitoring in calibration laboratories.

bARocAp Applications for measurements in pressurized systems

Vaisala DRYCAP

®

dew point instruments have a long history of providing reliable and stable measurements in compressed air systems and SF6 insulation gas monitoring in high-voltage equipment. In addition to the need for dew point measurement, these two applications also share the need for accurate and stable pressure measurement. Vaisala has integrated its DRYCAP and BAROCAP technologies into a range of products that offer a unique combination of pressure and dew point measurement for pressurized systems.

In compressed air, combining dew point measurement with live process pressure data provides a unique advantage: The conversion of measured pressure dew point to atmospheric pressure or ppm unit is available online, eliminating the possibility of any ambiguity in the dew point data. This is important because changes in the pressure of the gas being monitored alter its dew point.

Combined dew point and pressure measurement in SF6 gas monitoring of high-voltage equipment provides a superior tool for assessing the condition of SF6 insulation. Leakages can be immediately detected and early warning is given for moisture issues. Measuring dew point, pressure, and temperature enables the calculation of SF6 gas density, normalized pressure, dew point at atmospheric pressure, and ppm – all essential elements in SF6 monitoring.

BAROCAP sensor.

The story of BAROCAP began in the late 1970s during preliminary micromechanical pressure sensor studies for the new-generation

Vaisala Radiosonde RS80.

Micromechanics proved to be challenging, and Vaisala worked in close cooperation with universities and research institutes in Finland and internationally to develop a

Cross-section of the BAROCAP sensor.

The BAROCAP Story

new pressure-sensing technology based on silicon processing. The critical breakthrough came on the brink of the project deadline.

The first BAROCAP sensors were delivered to two icebreakers and the Helsinki Telephone Company.

BAROCAP sensors have traveled to places where no human has ever set foot, including as part of several

Mars exploration missions and the

Cassini-Huygens mission to explore

Saturn and its largest moon, Titan.

BAROCAP’s out-of-this-world journey continues with its inclusion in instruments that form part of

NASA’s Mars Science Laboratory, launched in November 2011.

- the Vaisala BAROCAP ® Sensor. It provides high measurement accuracy and excellent long-term stability.

highly Accurate

The PTB330 series is highly accurate.

The Class A barometers for the most demanding applications are fine-tuned and calibrated against a high-precision pressure calibrator.

Class B barometers are adjusted and calibrated using electronic working standard. All the PTB330 barometers come with a NIST traceable, factory calibration certificate.

Reliability through

Redundancy

According to customers’ choice, the

PTB330 can incorporate one, two or three BAROCAP

®

sensors. When two or three sensors are used, the barometer continuously compares the readings of the pressure sensors against one another and provides information on whether these are within the set internal difference criteria. This unique feature provides redundancy in pressure measurement.

Thus, users also get a stable and reliable pressure reading at all times as well as a pre-indication of when to service or recalibrate the barometer.

Qnh and QFe

The PTB330 can be set to compensate for QNH and QFE pressure used especially in aviation.

The QNH represents the pressure reduced to sea level, based on the altitude and temperature of the observation site. The QFE represents the height corrected pressure of small differences in altitude, for example, the air pressure at the airfield elevation.

Graphical display

The PTB330 features a multi-lingual, graphical display allowing users to monitor measurement trends. The graph is updated automatically while measuring and it provides a one-year measurement history. In addition to instant pressure, the PTB330 also provides the WMO pressure trend and tendency codes.

Applications

The PTB330 can be used successfully for aviation, professional meteorology, and for demanding industrial pressure measurement applications such as accurate laser interferometric measurement and exhaust gas analysis in engine test benches.

Digital Barometer

PTB330 is a new generation barometer designed for a wide range of high-end atmospheric pressure measurement. The pressure measurement of the PTB330 is based on the Vaisala in-house, silicon capacitive, absolute pressure sensor

– the Vaisala BAROCAP

®

Sensor. It provides high measurement accuracy and excellent long-term stability.

high Accuracy

The PTB330 series features extremely high accuracy. Class A barometers for the most demanding applications are fine-adjusted and calibrated against a high-precision pressure calibrator.

All the PTB330 barometers come with a NIST traceable, factory calibration certificate, also optional ISO/IEC

17025 accreditation calibration services are available.

Reliability through

Redundancy

According to customers’ choice, the

PTB330 can incorporate one, two or three BAROCAP

®

sensors. When two or three sensors are used, the barometer continuously compares the readings of the pressure sensors against one another and provides information on whether these are within the set internal difference criteria. This unique feature provides redundancy in pressure measurement. Thus, users get a stable and reliable pressure reading at all times as well as a pre-indication of when to service or re-calibrate the barometer.

sph10/20 static pressure heads for minimizing wind induced error

Wind induced effects are one of the main sources of error when measuring barometric pressure.

Variations due to strong and gusty wind can be overcome by using a static pressure head to ‘filter out’ the effect of dynamic pressure.

The Vaisala Static Pressure Head

Series SPH10/20 are designed to minimize the errors caused by wind.

The wind tunnel tested structure is both horizontally and vertically symmetrical. This design ensures reliable barometric pressure measurements in all weather.

ideal for outdoor installations

Vaisala’s static pressure heads are available in two models: the

Vaisala Static Pressure Head SPH10 is a basic version, and the Vaisala

Static Pressure Head SPH20 is a heated version for reliable operation in snowy and icy conditions. The warmed SPH20 contains a thermostat that switches on the warming power at temperatures, where the risk of icing may occur.

Composed of ultraviolet stabilized PC plastics and offshore aluminium, the

SPH10/20 static pressure heads are durable and weather resistant.

The SPH10/20 protects against rain and condensed water, thus preventing capillary condensation of a water column in the pressure channel which results in pressure error. The drain holes in the lower plate allow rain and water to flow out. The static pressure heads have internal netting which prevents insects and debris from blocking the pressure channel.

carefree maintenance

The SPH10/20 static pressure heads are easy to install and disassemble, service and clean – even at the installation site. Vaisala BAROCAP ®

Digital Barometer PTB210 can be installed directly on top of the

SPH10/20 static pressure heads.

Other barometers can be connected to the heads with pressure tubing.

SPH10 and SPH20 are a perfect pair for all Vaisala barometers. They ensure an accurate and reliable measurement in all weather conditions.

The SPH10/20 is easy to install and connect. In the picture, a SPH10 is connected to a PTB210 barometer.

170 reliable and repeatable measurement.

The sensor uses a micro-machined, ultra-thin silicon diaphragm which provides inherent sensor repeatability and stability. The sensor enables precise measurement and control in high performance cleanrooms. The PDT102 transmitter is available with voltage output

(3-wire) or current output (2-wire).

Available options

Online monitoring of the PDT102 is simple using the optional process valve actuator and the front access test jacks. The front access test jacks provide online process reference signal or calibration signal without disconnecting power supply wiring.

Measurements can be made using a standard multimeter.

Vaisala wind and weather sensor technologies for measurements in industrial Applications

Vaisala's long history in wind and weather measurements started already in the 1930s from the development of a radiosonde to measure the conditions in the upper atmosphere. Today, Vaisala wind and weather instruments are used in dozens of applications and industries all over the world.

industrial Applications for wind and weather measurements

Wind and weather data are required in many activities across industries.

For example, in power industry, the efficiency of power lines is a function of wind speed and direction.

Nuclear power plants require wind data for safety reasons to be able to model the dispersion of potentially radioactive leakages. In addition to nuclear power plants, also chemical factories need to gather wind data for dispersion monitoring.

Accurate outdoor measurements are essential in operating modern buildings. Processes such as free cooling, natural ventilation, and automated shading are dependent on real-time weather data. Ventilation control in greenhouses also relies on localized weather data to ensure an optimized environment for plant growth.

Vaisala wind and weather instruments

Ultrasonic Wind Sensor uses ultrasound to determine wind speed and direction. The sensor has no moving parts, which makes it independent of the limitations of mechanical wind sensors such as friction, inertia, time constant, over-speeding, and starting treshold.

How It Works

WINDCAP

®

sensor features an array of three ultrasonic transducers oriented to form an equilateral triangle. Wind measurement is based on time of flight (TOF) of the sonic impulse - the time it takes for the signal to travel from one transducer to another. TOF is measured in both directions for each pair of transducer heads. Simple algebra allows solving for the parallel component of wind velocity independently of the static speed of sound.

Sensor is an acoustic sensor that measures the impact of individual raindrops on a smooth stainless steel surface using a piezoelectric detector. The sensor provides real time information on rain intensity, duration, and accumulated rainfall.

How It Works

The RAINCAP

®

sensor consists of a round stainless steel cover, approximately 90 mm in diameter mounted to a rigid frame. A piezoelectric detector is located beneath the cover.

Raindrops hit the RAINCAP

®

sensor surface at terminal velocity, which is a function of the raindrop diameter.

Rain measurement is based on acoustic detection of each individual rain drop as it impacts the sensor cover. Larger drops create a larger acoustic signal than smaller drops.

The piezoelectric detector converts the acoustic signals into voltages. Total rain is calculated from the sum of the individual voltage signals per unit time and the known surface area of the RAINCAP

®

sensor. In addition, the intensity and duration of rain can be calculated.

The Vaisala WINDCAP

®

Ultrasonic

Wind Sensor WMT52 incorporates decades of Vaisala experience in wind measurement using ultrasound to determine horizontal wind speed and direction.

With no moving parts, the WMT52 has high sensitivity as the measurement time constant and starting threshold are virtually zero. This makes it superior to the conventional mechanical wind sensors.

The WMT52 is designed to operate without periodic field calibration and maintenance.

Applications

The WMT52 is ideal for use in marine applications as the housing with the mounting kit is water resistant.

The WMT52 is also suitable for wind energy and environmental monitoring, for example, for measuring the distribution of air pollution and road tunnel ventilation.

easy to install

The WMT52 is delivered fully assembled and configured from the factory. With the Vaisala

Configuration Software Tool you can change the settings, such as averaging times, output mode, update intervals, measured variables and message contents.

The WMT52 can be mounted either on top of a pole mast or on a cross arm.

When using the optional mounting kit, the north alignment needs to be performed only once.

heating

The optional heating available in the

WMT52 assists measurements in the freezing weather conditions and during snowfall.

As the heating circuit is independent of the operational power, separate supplies can be used. Heating is switched on automatically at low temperatures, well before the freezing point.

low power consumption

The WMT52 has very low power consumption; during the idle mode the device typically consumes about

2 ... 3 mW.

wA15 wind set for high performance wind measurement

The WA15 is based on accurate sensors installed on a large crossarm. It is designed for demanding wind measurement applications.

With a proven track record of successful installations, the

Vaisala Wind Set WA15 has earned its reputation as the industry standard in the wind sensor market.

The WA15 consists of a Vaisala Anemometer WAA151, a

Vaisala Wind Vane WAV151, an optional crossarm, a power supply and cabling.

Anemometer with excellent linearity

The WAA151 is a fast response, low-threshold anemometer.

Three lightweight, conical cups mounted on the cup wheel, provide excellent linearity over the entire operating range, up to 75 m/s.

A wind-rotated chopper disc attached to the shaft of the cup wheel cuts an infrared light beam 14 times per revolution. This generates a pulse output from the phototransistor.

180

The output pulse rate is directly proportional to wind speed (e.g. 246 Hz = 24.6 m/s). However, for the highest accuracy, the characteristic transfer function should be used to compensate for starting inertia.

sensitive wind Vane

The WAV151 is a counter-balanced, low-threshold, optoelectronic wind vane. Infrared LEDs and phototransistors are mounted on six orbits on each side of a 6-bit GRAY-coded disc. Turned by the vane, the disc creates changes in the code received by the phototransistors. The output code resolution is ±2.8°.

heated bearings withstand cold weather

Heating elements in the shaft tunnels of both the anemometer and vane keep the bearings above freezing in cold climates.

complete package Available

The anemometer and vane are designed to be mounted on

Vaisala crossarms.

The WHP151 power supply provides the operating and heating power needed for the WA15. The power supply, as well as the signal and power cables are available as options.
