The function of temperature transmitter
A device that converts physical measurement signals or ordinary electrical signals into standard electrical signals or outputs them in a communication protocol. A temperature transmitter is an instrument that converts temperature variables into standardized output signals that can be transmitted, mainly used for measuring and controlling temperature parameters in industrial processes. The current transmitter converts the AC current of the measured main circuit into a constant current loop standard signal, which is continuously transmitted to the receiving device.
The temperature current transmitter converts the signal from the temperature sensor into a current signal and connects it to the secondary instrument to display the corresponding temperature. For example, if the model of the temperature sensor in the figure is PT100, the function of the temperature current transmitter is to convert the resistance signal into a current signal, input it into the instrument, and display the temperature.
