Sensor cap with
memory chip
A memory chip is integrated in the sensor cap. The following data is
stored on the memory chip:
 Type designation of the sensor cap
 Series number
 Data of the factory calibration
Intelligent membrane
(IQMC technology)
For each membrane the individual calibration values are determined by
a factory calibration and stored on the memory chip of the sensor cap,
ensuring maximum accuracy over the whole lifetime of the sensor.
