ISM - Intelligent Sensor Management
The module allows the connection of ISM sensors
1)
.
ISM is an open system that is compatible to existing connection systems (VP 8)
and permits the use of conventional sensors. The system is not restricted to pH
measurement. Sensors from different manufacturers can be connected.
During pH measurement it is still possible to continuously monitor the glass
and reference electrode.
ISM sensors have an “electronic datasheet” which allows the storage of addi-
tional 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. The sensors can be precalibrated in the lab.
On-site calibration/adjustment is no more required.
Information available in the ISM sensor
Each sensor is clearly identified by the unalterable factory data (manufacturer,
sensor description).
Data for predictive maintenance can be transferred from the meter to the sen-
sor (for example the maximally permitted number of CIP/SIP cycles).
Statistical data inform on the product life cycle of the sensor: data of the last
3 calibrations, cal record, buffer values, voltages, temperature, response time,
glass and reference impedance.
This allows a comprehensive diagnostic:
- Wear indication
- Adaptive calibration timer
Taking over the minimum/maximum temperature
The maximum temperature range is stored in the ISM sensor.
When "Sensor monitoring Auto" has been selected, the value pair for the
m minimum temperature is automatically taken over from the sensor.
