SenTix General information

General information

Automatic sensor
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. The data is recalled by the meter when the sensor is connected and is used for measurement and for measured value documen­tation.
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.
