NT93420 Temperature Transmitter Sensor
NT93420 Temperature Transmitter Sensor Operating Principle
NT93420 temperature transmitter uses thermocouple, thermal
resistance as temperature measuring element, output signal from
temperature measuring element to transmitter module, through steady
pressure filter, operation amplification, nonlinear correction, V /
I conversion. After constant current and reverse protection
circuits are processed, 4 〜20mA current signal 0-5V/0-10V voltage
signal and RS485 digital signal output are converted into 4 〜20mA
current signal with linear relationship with temperature.
