ISM - Intelligent Sensor Management

The O

2

4700i(X) ppb module allows the connection of sensors with ISM technology.

ISM is an open system that is compatible to existing

VarioPin (VP) connection systems and permits the use of conventional sensors. ISM is not restricted to O

2 measurement. Sensors from different manufacturers can be connected. During O

2 ous monitoring is still possible.

measurement continu-

ISM sensors have an “electronic datasheet” which allows the storage of additional operating parameters such as calibration date and settings directly in the sensor.

An ISM sensor is immediately identified due to the “Plug & Measure” concept. This ensures the clear assignment of a sensor to a measuring point. The risk of confusing the sensors is eliminated.

Information available in the ISM sensor

Each sensor is clearly identified by the unalterable factory data. They consist of information concerning manufacturer, production date, sensor description, application data, and original calibration data, as well as information on predictive maintenance, such as the maximum load index and maximally permitted number of CIP/SIP cycles.

Statistical data inform on the product life cycle of the sensor: data of the last

3 calibrations, adjustment record, media values, partial pressure, temperature, response time, impedance, air pressure.

This allows a comprehensive diagnostic:

- Calculation of the individual load index

- Wear indication

- Membrane body changes

- Inner body changes

Practical advantages of ISM sensors

(e.g. in biotech applications)

CIP (Cleaning in Place) / SIP (Sterilize in Place)

CIP/SIP cycles are used for cleaning or sterilizing the process-wetted parts in the process. They are performed for biotech applications, for example.

Depending on the application, one (hot acid, water) or more media (hot acid, water, hot alkaline solution, water) are used. The temperatures for CIP are around 80 °C, for SIP around 110 °C.

This procedure extremely stresses the sensors.

ISM sensors can release a message when a preset number of permitted CIP/SIP cycles is exceeded. This allows replacing the sensor in time.

Example of CIP cycle:

The device automatically recognizes the CIP and SIP cycles and correspondingly increments the counter. The user can specify the max. number of cycles and decide whether a message is to be generated when this number is exceeded.

These data are not overwritten even after sensor replacement.

The number of CIP cycles is shown in the sensor wear monitor of the

Diagnostics menu when an individual max value has been specified.

Calibration / adjustment

Note: Function check active

Current outputs and relay contacts behave as configured

• Calibration:

• Adjustment:

Detecting deviations without readjustment

Detecting deviations with readjustment

Caution:

Without adjustment every dissolved oxygen meter delivers an imprecise or wrong output value! After replacing the sensor, the electrolyte, or the sensor membrane, you must perform a calibration!

The resulting values must be taken over by an adjustment for calculating the measured variables (measured value display, output signals)!

Procedure

Every dissolved oxygen sensor has its individual slope and zero point. Both values are altered, for example, by aging. For sufficiently high accuracy of oxygen measurement, the meter must be regularly adjusted for the sensor data (calibration+adjustment).

Sensor replacement (First Calibration)

After replacement of the sensor, electrolyte or sensor membrane, a “First

Calibration” should be performed. During First Calibration, the sensor data are stored as reference values for the statistics.

The ”Statistics” menu of Diagnostics (Pg 76) shows the deviations of zero, slope, calibration temperature, calibration pressure and response time of the last three calibrations with respect to the reference values of the First

Calibration. This allows evaluation of the drift behavior and aging of the sensor.

Calibration/adjustment methods

• Automatic calibration in water/air

• Product calibration (saturation/concentration)

• Data entry

• Zero point correction

Adjustment means that the values determined by a calibration are taken over.

The values determined for zero and slope are entered in the calibration record. (Cal record can be called up in the Diagnostics menu for the module, see Pg 76).

These values are only effective for calculating the measured variables when the calibration has been terminated with an adjustment.

A passcode ensures that an adjustment can only be performed by an authorized person (Administrator).

The Operator can check the current sensor data by a calibration and inform the Administrator when there are deviations.

You can use the additional function SW 700-107 for granting access rights

(passcodes) and for AuditTrail (continuous data recording and backup according to FDA 21 CFR Part 11).

Recommendations for calibration

It is always recommended to calibrate in air. Compared to water, air is a calibration medium which is easy to handle, stable, and thus safe. In the most cases, however, the sensor must be dismounted for a calibration in air. When dealing with biotechnological processes which require sterile conditions, the sensor cannot be removed for calibration. Here, calibration must be performed with aeration directly in the process medium (e.g. after sterilization).

In the field of biotechnology often saturation is measured and calibration is performed in the process medium (water) for reasons of sterility.

For other applications where concentration is measured (water, waste water, etc.), calibration in air has proved to be useful.

Common combination: process variable / calibration mode

Measurement Calibration

Concentration

Water

Air

If there is a temperature difference between the calibration medium and the measured medium, the sensor must be kept in the respective medium for several minutes before and after calibration in order to deliver stable measured values. The type of calibration pressure detection is preset during parameter setting (Pg 55).

Automatic calibration in water

Automatic calibration in water

The calibration value is always the oxygen saturation (referred to air).

First, the slope is corrected using the 100 % value.

During calibration the M 700 is in function check mode.

Current outputs and relay contacts behave as configured (BASE, Out, PID modules).

Caution!

Ensure sufficient medium flow to the sensor (see Specifications of dissolved oxygen sensors). The calibration medium must be in equilibrium with air.

Oxygen exchange between water and air is very slow. Therefore, it takes a relatively long time until water is saturated with atmospheric oxygen. If there is a temperature difference between calibration medium and measured medium, the sensor must be kept in the respective medium for several minutes before and after calibration.

Product calibration: Saturation

Product calibration: Saturation

(Calibration with sampling)

When the sensor cannot be removed – e.g. for sterility reasons – its slope can be determined with “sampling”. To do so, the currently measured saturation value of the process is stored by the analyzer. Directly afterwards, a reference value is determined using a portable meter, for example. The reference value is entered into the measuring system. From the difference between measured value and reference value, the analyzer calculates the sensor slope. With low saturation values, the analyzer corrects the zero point, with high values the slope.



Caution!

The reference value must be measured at temperature and pressure conditions similar to those of the process.

The sensors of the InPro 6800 Series have a very low zero point current.

Therefore, a zero calibration is only required for measurement of oxygen traces.

If a zero point correction is performed, the sensor should remain for at least

10 to 30 minutes in the calibration medium in order to obtain stable, nondrifting values. During zero point correction, a drift check is not performed.

Zero point current of a properly functioning sensor is notably less than 0.5 % of air current.

The values determined for zero and slope are entered in the calibration record. (Cal record can be called up in the Diagnostics menu for the module).

These values are only effective for calculating the measured variables when the calibration has been terminated with an adjustment.

A passcode ensures that an adjustment can only be performed by an authorized person (Administrator).

The Operator can check the current sensor data by a calibration and inform the Administrator when there are deviations.

Output filter

Time constant

Time constant of output filter

To smoothen the current output, a low-pass filter with adjustable time constant can be switched on. When there is a jump at the input (100 %), the output level is at 63 % after the time constant has been reached.

The time constant can be set from 0 to 120 sec. If the time constant is set to 0 s, the current output follows the input.

Note:

The filter only acts on the current output and the current value of the secondary display, not on the measurement display, the limit values, or the controller!

You can define a delay time for “Maintenance request” and “Failure”, resp. If an alarm message is released, the contact will only be activated after expiry of this delay time.

Failure is active when a value has exceeded (or fallen below, resp.) a preset ”Failure Limit Hi” or ”Failure Limit Lo”, when the measured value is out of range or in the event of other failure messages. That means that the equipment no longer operates properly or that process parameters have reached a critical value.

Failure is disabled during function check.

Maintenance request is active when a value has exceeded (or fallen below, resp.) a preset “Warning Limit

Hi” or “Warning Limit Lo”, or when other warning messages have been activated. That means that the equipment is still operating properly but should be serviced, or that process parameters have reached a value requiring intervention.

Warning is disabled during “Function check”.

Function check is active:

• during calibration

• during maintenance (current source, meas. point maintenance)

• during parameter setting at the Operator level and the Administrator level

• during an automatic rinsing cycle.

Relay contacts: Protective wiring

Protective wiring of relay contacts

Relay contacts are subjected to electrical erosion. Especially with inductive and capacitive loads, the service life of the contacts will be reduced.

For suppression of sparks and arcing, components such as RC combinations, nonlinear resistors, series resistors and diodes should be used.

Warning!

Make sure that the maximum ratings of the relay contacts are not exceeded even during switching!

Information concerning relay contacts

As delivered, the relay contacts are suitable for low signal currents (down to approx. 1 mA). If currents above approx. 100 mA are switched, the gold plating is destroyed during the switching process. After that, the contacts will not reliably switch low currents.

Appendix:

Minimum measuring spans for current outputs

The O

2

4700i(X) ppb module is a measuring module. It does not provide current outputs. Current outputs are provided by the M 700 BASE (basic device) or by communication modules (e.g. Out, PID). The corresponding parameters must be set there.

The minimum current span shall prevent that the resolution limit of the measurement technology (± 1 count) is seen in the current.

High CO

2 compensation (SW 700-011)

Application-specific additional function for breweries

This additional function simplifies parameter setting since all steps not required for dissolved oxygen measurement in carbonated beverages are omitted. It simultaneously acts on all installed O

2

(module software version 2.2 and higher).

modules

Function principle:

The following processes are automated by the additional function, i.e. all parameters required for the respective program step are set automatically.

During the filling process, for example, it must be ensured that as little oxygen as possible is dissolved in the beer to extent its shelf life.

During oxygen trace measurement the sensor is operated with a very low polarization voltage (-500 mV). This results in low cross-sensitivity to CO

2

.

For a calibration in air, this polarization voltage is too low.

It must be set to -675 mV and afterwards be reduced again to -500 mV for measuring in the trace range.

Be sure to wait long enough for the sensor to stabilize.

Opening and closing of valves causes pressure variations in the beer pipes which momentarily falsify the O

2 signal. Therefore the input signal must be attenuated correspondingly to suppress transient interferences.
