Operator's Guide
OS-PC
The OS-PC is a non-contact temperature sensor with built-in LED sighting. It has an extremely
fast response time, and can measure a spot as small as 1.6 mm in diameter.
The continuous LED sighting illuminates the position and size of the measurement spot while
readings are being taken, without affecting the accuracy of the measurement.
The sensor works by detecting the infrared radiation emitted from a surface as a result of its
own temperature. The amount of radiation emitted is related to the temperature, and the
sensor uses this relationship to provide an accurate temperature measurement.
OS-PC sensors are ideal for measuring the surface temperature of paper, thick plastics, food,
rubber, electronic components, cable, ceramics, textiles, painted surfaces and some metals,
as well as many other materials.
OS-PC-TSD
The OS-PC-TSD is an optional multilingual touch screen interface module for the OS-PC
sensor. It functions as a standalone temperature indicator, alarm unit and configuration tool,
and a selectable analogue output allows it to be connected to further instrumentation.
All the settings of the OS-PC sensor are adjustable via the built-in touch screen interface.
When an optional MicroSD Card is inserted into the OS-PC-TSD, the system functions as a
fully-configurable temperature data logger.

PyroCube sensor are valid up to the
maximum distances shown.
Emissivity Adjustment
The default emissivity setting is 0.95. It may be adjusted in two ways via the touch screen
interface:
Settings Input Settings Emissivity & Compensation Emissivity & Compensation
Settings
Enter the target emissivity here. For help with finding the target emissivity, contact Omega.
Settings Input Settings Emissivity & Compensation Teach Emissivity
Measure the true surface temperature using another device, such as a trusted contact
thermometer. Enter the true temperature here, and the sensor calculates the correct emissivity
setting.
To use this function, the target temperature must be greater than 50°C.
Reflected Energy Compensation
Settings Input Settings Emissivity & Compensation Emissivity & Compensation
Settings
Some of the infrared energy detected by an infrared temperature sensor is not emitted by the
target, but is a reflection of its surroundings.
To ensure an accurate reading, the sensor needs to know the temperature of the source of
that reflected energy. In most applications, the surroundings of the target have the same
temperature as the sensor itself (e.g. the sensor and target are in the same room). The sensor
automatically compensates for the reflected energy, so Reflected Energy Compensation is not
required.
However, in some applications, the source of the reflected energy (the surroundings of the
target) is much hotter or colder than the sensor itself. In these cases, Reflected Energy
Compensation should be enabled.
For example, if the target is inside a furnace and the sensor is outside, the reflected energy is
coming from the inner walls of the furnace. Use the Teach Reflected Temperature function to
find the correct setting. Enter the true target temperature and the sensor will compensate for
the reflected energy.
For assistance, contact Omega.
Alarm Outputs
When used without the optional OS-PC-TSD interface module, the sensor has one open drain
alarm output, configurable via RS232C Modbus. The output is rated 27 V DC, 0.2 A.
The OS-PC-TSD has two individually-configurable alarm relay outputs. These are rated
24 V DC, 1 A. These are individually configurable via the touch screen interface.
Each alarm has two set point temperatures (Low and High). The behaviour of the alarm
depends on the Alarm Mode.

For “Error On” and Error Off” alarms, the alarm monitors for an internal voltage abnormality. In
the event of such an error, an “Error On” alarm will be ON and an “Error Off” alarm will be OFF.
OS-PC-TSD Touch Screen Interface Module
The backlit touch screen interface module provides a large, bright display of the measured
temperature, two alarm relay outputs, and options for full configuration of the sensor.
The graph view shows the history of the measured temperature. In alarm conditions, the
display changes colour to provide an immediate and obvious alarm indication. Alarm modes
and levels can be configured via the touch screen.

automatically compensate for reflected energy. For more information, see
the “Reflected Energy Compensation” section of this guide.
Settings Input Settings
Peak Hold
With Peak Hold, the sensor will continue to display or output a peak
in the measured temperature for a certain time. This feature is ideal
for monitoring the temperature of individual objects on a conveyor,
and for ignoring unwanted low readings, such as when a rotating
stirring arm in a container of liquid passes the sensor.
Reset
The peak hold mode. Choose from Time or Discharge:
Time
The output returns instantly to the measured temperature
after the Reset/Discharge Time.
Discharge
The output decreases steadily after a peak. The rate of
decay depends on the Reset/Discharge Time and the
Discharge Level.
Reset/Discharge Time
The peak hold period. This depends on the “Reset” setting.
Discharge Level
In “Discharge” mode, this is the percentage of the measured
temperature that the peak hold temperature will reach after the
Reset/Discharge Time has elapsed.
Discharge Level has no effect when “Time” mode is enabled.
Peak Hold Off/On
Enable or disable peak hold processing.
Averaging
Select the required averaging period to smooth the output and slow down the
sensor’s response time. The default setting is 50 ms.
Note: averaging prevents the sensor from following rapid temperature
changes.
Correction
Correction Span
Adjusts the gain (slope) of the sensor’s measured temperature
response. For example, this can be used when measuring through a
window to correct for transmission loss.
The sensor is calibrated in the factory with Correction Span set at
1.000 and this setting should not normally be adjusted.
Note: When Correction Span is set lower than 0.9, the upper limit of
the temperature range is reduced below the published specification.
Correction Offset
This value is added to the measured temperature.

Data Logging Specifications
The OS-PC and OS-PC-TSD can be used as a standalone data logger. Data logging can be
configured via the touch screen interface.
Data is stored on a MicroSD card in .csv format and can be viewed and edited easily using
spreadsheet software. The MicroSD card is available as an optional accessory, with an SD
Card adapter to transfer data to a PC.
With a 2 GB card, the user can store 28.4 million readings, which is almost 1 year’s worth of
data at 1 sample per second. Larger cards provide more storage.
The MicroSD card slot and battery holder are located on the touch screen circuit board in the
lid of the OS-PC-TSD. Readings are time and date stamped using the unit’s internal clock.
The clock is reset when the power is disconnected, or it will continue if the optional battery is
fitted.
Using the OS-PC-TSD as a Data Logger
1. Insert a MicroSD card into the holder on the circuit board inside the lid of the OS-PC-TSD.
2. To retain the date and time when the unit is switched off, fit a battery to the holder on the
circuit board inside the lid.
3. Replace the lid and connect the sensor power supply.
4. To set the number of samples to be logged, the time period between samples, and, if
required, to schedule data logging to automatically start, press
menu, then press
to access the Data Logging options.

9. To transfer data to a computer, remove the MicroSD Card from the unit, insert the card into
the SD Card adapter (supplied with the MicroSD Card, accessory model MSD) and insert the
adapter into an SD Card reader.
Installation of MicroSD Card and Battery
The MicroSD Card and battery slots are located on the touch screen circuit board. Unscrew
the lid of the OS-PC-TSD to access them.
The battery is optional. With a battery fitted, the internal clock will continue to run when the
power is off. Without a battery, the unit will request the date and time each time the power is
cycled.
All other settings are stored in permanent memory and will be preserved when it is switched
off, regardless of whether a battery is fitted.
Data Log Files
Data is saved to the MicroSD Card in .csv format. This file format can be opened or imported
by spreadsheet software such as Microsoft Excel.
A new folder is created on the MicroSD Card for each day that data is logged.
A new log file is created every time logging is started. The start time is used as the file name.

existing sensor.
Cooling water flow rate should be
approximately 0.6 l/min.
The integrated air purge must be used to
stop condensation forming on the lens while
the sensor is being cooled.
Note: The sensor output cable is rated to
80°C ambient temperature.
Installation
The installation process consists of the following stages:
-
Preparation
-
Mechanical installation
-
Electrical installation
Please read the following sections thoroughly before proceeding with the installation.
Preparation
Distance and Spot Size
The size of the area (spot size) to be measured determines the distance between the sensor
and the target. The spot size must not be larger than the target. Choose a suitable mounting
distance so that the measured spot size is smaller than the target.
Reflections
The sensor must be installed in a location where energy from tungsten lamps, heaters and
sunlight cannot be reflected from the target into the lens. This is especially important for lowtemperature targets. Using fluorescent or mercury lamps, or using shields, may help in this
respect. For further information and assistance, contact Omega.
Ambient Temperature
The sensing head may be used between 0°C and 50°C ambient temperature. If the ambient
temperature is higher than this, consider adding a water cooled jacket.
Avoid thermal shock. Allow 20 minutes for the unit to adjust to large changes in ambient
temperature.
Atmospheric Quality
Smoke, fumes, dust or steam can contaminate the lens and cause errors in temperature
measurement. Carbon dioxide can also influence the reading.
In these types of environment, the amount of contaminant should be minimised, and the air
purge collar should be used to help keep the lens clean.
Electrical Interference
The OS-PC is tested to industrial standards for electromagnetic compatibility (EMC). To
minimise electromagnetic interference or ‘noise’, the sensor should be mounted away from
motors, generators and such like.
Power Supply
The required supply voltage is 5 to 27 V DC. When using the sensor on its own (without the
OS-PC-TSD touch screen terminal) the minimum supply voltage depends on the output.
Ensure the power supply is of the correct voltage and is capable of providing an output current
of at least 100 mA.
Mechanical Installation
All sensors come with a 2 m, 5 m or 10 m cable as standard (see Model Numbers). The cable
may be lengthened using the Extension Cable accessory.
-
Affix the sensor to its mounting. The sensor can be mounted on brackets of your
own design, or you can use the mounting bracket accessory.
-
Switch on the LED sighting to illuminate the measured spot, and adjust the angle of
the sensor to aim it.
-
Ensure the target is larger than the illuminated spot. If not, adjust the measurement
distance for a smaller spot size.
Note: The sensor housing must be connected to earth at one point, either the housing of the
sensing head, the electronics module, or the output cable shield termination. To avoid ground
loops, please ensure the sensor is grounded at only one of these points.
Electrical Installation

Operation
Once the sensor is in position and the appropriate power, air and cable connections are
secure, the system is ready for continuous operation by completing the following simple steps:
1.
Turn on the sensor power supply
2.
Turn on the connected instrumentation
3.
Read, monitor or log the temperature
Important
Be aware of the following when using the sensor:
•
If the sensor is exposed to significant changes in ambient temperature (hot to cold,
or cold to hot), allow 20 minutes for the temperature to stabilise before taking or
recording measurements.
•
When power is switched on, allow the sensor to warm up for 1 minute before taking
or recording measurements.
•
Do not operate the sensor near large electromagnetic fields (e.g. around arc
welders or induction heaters). Electromagnetic interference can cause
measurement errors.
•
Wires must be connected only to the appropriate terminals.
Viewing through a window
The sensor is capable of measuring the temperature of a target through a window made of a
suitable infrared-transmissive material. The emissivity setting of the sensor should be adjusted
to compensate for the presence of the window. Please contact Omega for more information on
using the sensor with a window.
Maintenance
Our customer service representatives are available for application assistance, calibration,
repair, and solutions to specific problems. Contact our Service Department before returning
any equipment.
In many cases, problems can be solved over the telephone. If the sensor is not performing as
it should, try to match the symptom below to the problem. If the table does not help, call
Omega for further advice.

Lens cleaning
The lens must be kept clean and dry for maximum accuracy. Check the condition of the lens
regularly.
If the lens has become dirty, the measurement accuracy will be affected. Blow off loose
particles (if not using the air purge accessory) with an air “puffer”.
