Temperature transmitters are used with temperature sensors and serve the purpose of transmitting the signal to a control or monitoring system. Two types of sensors used with temperature transmitters include RTD’s and thermocouples. The signal inputs from these sensors are received by temperature signal conditioning devices, which convert the inputs into analog or digital signals Typical applications for temperature transmitters include industrial, manufacturing, pharmaceutical, food and beverage, and agriculture.
Temperature transmitter converts the thermocouple or RTD signal to a 4-20 mA output signal and is the ideal solution for many remote temperature measurement applications. 4-20ma transmitters have definite advantages over conventional temperature measuring devices, but must be selected with caution in order to avoid ground loop problems.
