The temperature transmitter uses thermocouples and resistance temperature detectors as the temperature-sensing elements. The signals from these elements are sent to the transmitter module, where they undergo circuitry processes including voltage stabilization and filtering, operational amplification, nonlinear correction, V/I conversion, constant-current regulation, and reverse-protection features. These steps ultimately convert the signals into a 4–20mA current signal or a 0–5V/0–10V voltage signal that has a linear relationship with the temperature, along with an RS485 digital signal output.
