Explosion Proof Integrated Temperature Transmitter 4-20mA Digital Local Display Sensor Thermal Resistance Pt100

Product description

This product is a kind of configurable intelligent temperature transmitting sensor. It receives 2, 3 and 4-wire Pt100 thermal resistance input, conducts linear processing for input signal and outputs 4-20mA standard signal. It has the function of sensor open circuit fault alarm.

Applications

It can directly measure the temperature of liquid, gas or steam medium. It receives the input signal of standard graduation thermal resistance and generates 4~20mA standard signal with linear temperature to be measured. It matches with computer system to detect and control various temperatures.
