Temperature Transmitter

Temperature transmitter using thermocouple, thermal resistance as a temperature measuring element, from the temperature measuring element output signal to the transmitter module, after stabilizing filter, operation amplification, nonlinear correction, V/I conversion, constant current and reverse protection circuit processing, converted into a linear relationship with the temperature of 4 ~ 20mA current signal 0-5V/0-10V voltage signal, RS485 digital signal output.
