What is temperature transmitter?


The temperature transmitter uses a thermocouple and a thermal resistor as the temperature measuring component,

and sends the signal from the temperature measuring component to the transmitter module. After voltage regulation 

filtering, operational amplification, nonlinear correction, V/I conversion, constant current and reverse After protection

and other circuit processing, it is converted into a 4-20 mA current signal 0-5V/0-10V voltage signal linearly related 

to temperature, RS485 digital signal output.


Temperature transmitter function´╝Ü


A temperature transmitter is a device that can convert a physical measurement signal or a common electrical signal

into a standard electrical signal output or can be output by a communication protocol, and is mainly used for measuring

and controlling temperature parameters of industrial processes. 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.

For example, the temperature transmitter of the model PT100 is used to convert the resistance signal into a current

signal, input the meter, and display the temperature.
