MP200i

Isolated Programmable Temperature Transmitter

The MP200i series is a 2 wire temperature transmitter with galvanic isolation between input and output. Micro-processor based, it was designed for flexibity, accepting mV, Pt100 and a variety of thermocouples as the input sensor. Why use isolated transmitters? Isolated transmitters protect the electrical instruments by eliminating ground loop effects and reduce substantially the undesirable interferences and instabilities in sensor measurements.
