The GEN 210 is a second generation ‘Smart’ in head temperature transmitter that accepts any commonly used temperature sensor, slide-wire transducer or Millivolt signal and converts the output to the industry standard 4-20mA transmission signal.

The sensor type and range are easily programmed using a software package running under ‘WindowsTM’ on a PC which communicates, via an interface adapter, down the same pair of wires that carry the 4-20mA output signal.

The Process Variable may be filtered to remove incoming signal noise using one of the four settings. If the ‘Adaptive ‘ function is selected the filter continuously adjusts to the incoming signal to noise ratio in order to choose an appropriate level of filtering. In this way a slowly changing input can be heavily filtered but if the signal goes through a sudden change the filter quickly reduces allowing a rapid response.
