The SEM203W potentiometer transmitter is designed for use with potentiometer sensors, converting their output to a (4 to 20) mA transmission signal. It features push-button configuration for easy range selection, LED over-range indication, sensor matching, high stability, and fast response time. The transmitter allows for manual adjustment of the transmitter range using a single push button and LED indicator. The device ensures accurate and low drift performance, with a fast response time of less than 50 ms to reach 70% of the final output value for a change in the input signal. Any potentiometer value between 1 and 100K ohms can be used with this transmitter.
