SEM210 Temperature Transmitter

Brand: Status Instruments

The SEM210 is a second generation ‘Smart’ Universal input in-head temperature transmitter that accepts RTD, Thermocouple, Potentiometer, Slidewire transducer or Millivolt signal and converts the output to the industry standard 4-20 mA transmission signal. 

The sensor type and range are easily programmed using a PC and our free configuration software download from our web site. 

Connection from the PC USB port and the SEM210 is made using the USB port powered configurator. 

This simplifies connection and allows for re-programming or interrogation of the SEM210 while it is installed in the loop or not. 

Sensors can be changed without the need for re-calibration.
