The transmitter is a device that converts a physical measurement signal or a normal electrical signal into a standard electrical signal output or that can be output as a communication protocol.
A temperature transmitter is a meter that converts temperature variables into a standardized output signal that can be transmitted. It is primarily used for measurement and control of temperature parameters in the industrial process.
The current transmitter converts the AC current of the main circuit under test into a constant current loop standard signal and continuously delivers it to the receiving device. The temperature-current transmitter converts the signal of the temperature sensor into a current signal and connects it to the secondary meter to display the corresponding temperature.
