Temperature transmitters

What is a temperature transmitter?

A temperature transmitter converts the input signal from a temperature sensor like RTD (Resistance Temperature Detector, e.g. Pt100, Pt1000) or thermocouple into a stable 4-20 mA output signal. A common application is to monitor the temperature of a remote process, but since the raw signal from the temperature sensor is weak, the transmitter amplifies it by converting it to a standardized electrical signal. The most widespread temperature transmitters are 2-wire, but there are also 3-wire and 4-wire. A digital temperature transmitter or SMART transmitter provides both analog 4-20 mA signal and digital communication signal most commonly using the HART protocol.
