ENDRESS+HAUSER TMT112-A1KCA

ENDRESS+HAUSER TMT112-A1KCA

Product Description

The iTEMP HART TMT112 is a DIN rail temperature transmitter with HART® protocol. It is a universal transmitter that accepts inputs from resistance thermometers (RTD), thermocouples (TC), resistance transmitters (Ω), and voltage transmitters (mV), converting these signals into a scalable 4 to 20 mA analog output signal. It is designed for universal settings with HART® protocol for various input signals.
