RTD Transmitter RT 98

          RTD transmitter RT 98 are compactly designed for converting the variations of resistance in a Pt 100 temperature sensor to a linearized and isolated DC. voltage or current output. They provide constant current excitation and true lead length compensation when used with a 3 – wire RTD, which can be located at a considerable distance from the transmitter.
