SEM203W Temperature Transmitter

Brand: Status Instruments

The SEM203/W is a “smart” in head transmitter that accepts slide wire 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 the desired transmitter range manually, by setting the slide wire position and pressing button to store at both 4 mA and 20 mA points.

The SEM203W in head transmitter incorporates the latest digital technology to ensure accurate drift free performance.
