The SEM206 is our entry level PC programmable temperature transmitter. There are three versions for Pt100, Thermocouple and Thermistor sensors. It will convert the sensor output to a standard industrial (4 to 20) mA transmission signal. PC configuration allows the user to select range, units and burnout direction, without requiring calibration equipment. Configuration is performed quickly using our USB port driven configurator by simply connecting two clips to the SEM206 loop terminals and following the software instructions. Calibration set up may be saved as a file on the PC for later use.
