a
The manufacturing-related deviation of the sensor can be equalized on the transmitter. The measuring accuracy
of the overall conductivity measurement is determined by the transmitter used. Therefore, it is not possible to make
a general assertion as to the accuracy of the measuring system.
b
The measuring range also depends on the transmitter being used.
c
DIN EN 60751.
d
Please also refer to the dimensional drawings for the sensors.
e
Valid for the electrical connection.
