SEM203TC Temperature Transmitter

Brand: Status Instruments

The SEM203TC is a cost effective “smart” in head transmitter that accepts thermocouple temperature sensors and converts sensor output over a configured range to a standard industrial (4-20 mA) transmission signal. 

A simple push button operation allows the user to select TC type, Burnout direction, Select fixed ranges and trim (4 and 20) mA points. 

The SEM203TC in head transmitter incorporates the latest digital technology to ensure accurate drift free performance. 

If required the desired range can be specified at the time of order, removing the need for user configuration. 

If the range is not specified then the transmitter will be shipped with the default range of (0 to 1,000)° C type K.
