The WT120 head transmitter converts a temperature signal in a 4 to 20 mA or 20 to 4 mA standard signal.
The supply of the signal converter from the current loop.
Here the output signal is linearly proportional to the input The signal converter can be completely adjusted before the assembly over the software and is immediately ready for use.
