MP300i Series Programmable Temperature Transmitter

Brand: Intempco Controls, Inc.

MP300i series is a high performance temperature transmitter which converts RTDs, Thermocouples and voltage signals into a 4-20 mA current along with a superimposed HART protocol digital communication.

Complete configuration, calibration and parameters monitoring can be fully achieved through the two-wire current loop by means of a convenient PC software and USB interface called TxConfig-HART.

Sensor type input is fully programmable for most relevant RTDs, thermocouples, variable resistors, and voltage in mV.

High Isolation between input and output drastically improves stability and reliability with greater immunity to electromagnetic noises in extremely harsh industrial environments.
