The SEM203 series is a low cost configurable in-head transmitter that accepts either PT100 temperature sensors (P), thermocouple (TC) or slidewire (W) input. It 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 desired range and burnout direction but also perform user trim at both (4 and 20) mA points.
