General information
Automatic sensor
recognition
The sensor electronics with the stored sensor data are in the connecting
head of the electrode. The data include, among other things, the sensor type
and series number. In addition, the calibration data are stored in the sensor
with each calibration and the calibration history is recorded (the last 10 cali-
brations). 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 different
meters. On the other hand, different calibrated sensors can be used with one
meter without the need to recalibrate.
The digital transmission technique guarantees the failure-free communica-
tion with the meter even with long connection cables. If the sensor firmware
is enhanced by WTW, it can be updated via the meter.
Armoring
A 925-P/K and
A 925-P/S
(accessories)
To protect the electrode against mechanical impacts, the A 925-P/K armoring
(with plastic protective hood) or A 925-P/S (with steel protective hood) can be
installed and uninstalled as necessary. The steel model is simultaneously
used as a sinker for depth measurements.
