WIKA operating instructions model T32.xS 21
Freely programmable sensor functionality when 2 sensors
have been connected (dual sensor)
Sensor 1, sensor 2 redundant:
The 4 … 20 mA output signal delivers the process value of sensor 1.
If sensor 1 fails, the process value of sensor 2 is output (sensor 2 is
redundant).
Average value:
The 4 … 20 mA output signal delivers the average value from
sensor 1 and sensor 2. If one sensor fails, the process value of the
working sensor is output.
Minimum value:
The 4 ... 20 mA output signal delivers the lower of the two values from
sensor 1 and sensor 2. If one sensor fails, the process value of the
working sensor is output.
Maximum value:
The 4 ... 20 mA output signal delivers the higher of the two values
from sensor 1 and sensor 2. If one sensor fails, the process value of
the working sensor is output.
Difference:
The 4 … 20 mA output signal delivers the difference between
sensor 1 and sensor 2. If one sensor fails, the process value of the
working sensor is output.
Freely programmable monitoring functions
Monitoring of the measuring range:
If this function is activated, an error is signalled on the current loop
(< 3.6 mA) if the measured value is either below or over the limits of
the measuring range.
