The temperature transmitter with thermal resistance consists of a reference unit, R/V conversion unit, linear circuit, reverse protection, current limiting protection, V/I conversion unit, etc. After the temperature measurement thermal resistance signal is converted and amplified, the nonlinear relationship between temperature and resistance is compensated by a linear circuit. After the V/I conversion circuit, a 4-20mA constant current signal is output that is linearly related to the measured temperature. Output signal: Current: 4-20mA
