Description
Thermocouple (resistance) with temperature transmitter, usually used in conjunction with display instruments, recording instruments, electronic computers, etc., with an output of 4~20mA. Direct measurement of liquid, steam and gaseous media and solid surface temperatures in the range of 0 to 1600C in various production processes.
Features:
O Two-wire output 4~20mA, strong anti-interference ability;
O Save the cost of compensation wire and installation of temperature transmitter;
O Large measuring range;
O Automatic compensation of cold junction temperature, nonlinear correction circuit.
working principle:
The change of the thermoelectric potential (resistance) measured by the thermocouple (resistance) in the working state will generate an unbalanced signal through the bridge of the temperature transmitter, and after amplification, it will be converted into a 4~20mA DC signal to the working instrument. The meter will display the corresponding temperature value.
