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.

Dierence:

The 4 … 20 mA output signal delivers the dierence 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.
