It is usually used with display meters, recording meters, and electronic computers, and outputs 4 to 20 mA. Direct measurement of liquid, vapor, and gaseous media and solid surface temperatures in the 0 to 1800°C range in various manufacturing processes.
● Two-wire output 4 ~ 20mA, strong anti-interference ability;
● Save the cost of compensation wire and installation temperature transmitter;
● large measurement range;
● Cold junction temperature compensation, nonlinear correction circuit.
Thermocouple (resistance) measured in the working state of the thermoelectric potential (resistance) changes, after the bridge of the temperature transmitter to generate an unbalanced signal, after amplification converted into a 4 ~ 20mA DC signal to the working instrument, work The meter will show the corresponding temperature value.
