What is a temperature transmitter?

A temperature transmitter is a combination of a temperature sensor such as a thermocouple or RTD and a transmitter that is placed in a device. The temperature sensor is the most important and main part of the temperature transmitter and it measures the temperature and also the transmitter amplifies the signal and transmits it to the monitoring system or control room. In other words, the temperature transmitter measures the temperature and converts it into a 4-20 mA signal corresponding to the measured temperature. The temperature sensor is located in the outermost part of the temperature transmitter and is directly connected with the temperature measurement environment, so that changes in the temperature of the environment cause changes in the temperature of the sensor.
