SEM203P Temperature Transmitter

Brand: Status Instruments

The SEM203/P is a low cost configurable in-head transmitter that accepts PT100 temperature sensors and converts sensor output over a configured range to a standard industrial (4 to 20) mA transmission signal. 

A simple push button operation allows the user to not only select the desire range and burnout direction but also perform user trim at both (4 and 20) mA points. 

The SEM203 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 100) ° C set.
