Rangeable Push Button RTD Transmitters

 

The SEM203 Series Push Button Transmitters are field rangeable, two-wire 4-20 mA transmitters used with Type 81 100Ω RTD sensors. The transmitters can be configured with a simple push button operation. The unit features selectable ranges, loss-of-sensor response, user trim for both 4 mA and 20 mA points, and reverse polarity protection. A bright LED provides visual indication of sensor fault and programming menus. The SEM710 Series Indicatiing Transmitter incorporates all of the features of the SEM203 but is instead configured through a USB Port and incorporates a bright red LED display for visual indication of temperature configurable in ℉ or ℃.
