SenTix General information
General information
Automatic sensor
recognition
The sensor electronics with the stored sensor data is in the connecting head
of the electrode. The data include, among other things, the sensor type and
series number. With each calibration, the calibration data is written in the
sensor and the calibration history is recorded. The data is recalled by the
meter when the sensor is connected and is used for measurement and for
measured value documentation. Storing the calibration data in the sensor
ensures that the correct slope and asymmetry are automatically used if the
sensor is operated with several meters.
The digital transmission technique guarantees the failure-free communication with the meter even with long connection cables. If the sensor firmware
is enhanced by WTW, it can be updated via the meter.
