Measurement system The iTEMP® HART® DIN rail TMT122 temperature transmitter is a 2-wire transmitter with an analogue output. It has measurement input for resistance thermometers (RTD) in 2-, 3- or 4-wire connection, thermo- couples and voltage transmitters. Setting up of the TMT122 is done using the HART® protocol with hand operating module (DXR275, DXR375) or PC (e.g. configuration software ReadWin® 2000 or FieldCare). Input Measured variable Temperature (temperature linear), resistance and voltage. Measuring range Depending upon the sensor connection and input signal.
