Temperature transmitter thermocouple, thermal resistance as temperature measurement devices, temperature measurement element to the output signal from the transmitter module, the regulated filter, operational amplifier, nonlinear correction, V / I conversion, constant current and reverse protection after processing circuit, it is converted into a linear relationship with the temperature of 4 ~ 20mA current output signal, and the signal transmitted to the control room equipment, general industrial field. For the industrial site monitoring, display and other uses, to ensure the reliability and safety of the field operation and process control equipment. Widely used in petroleum, chemicals, chemical fiber; textile, rubber, building materials; electricity, metallurgy, medicine; food industry and other field temperature process control; especially suitable for computer control system. 

Features: 
Two-wire 4 ~ 20mADC output. Transmission distance, anti-jamming; cold end, temperature drift, non-linear automatic compensation; 
High accuracy, good long-term stability; 
The temperature inside the module using epoxy resin casting process for a variety of harsh and hazardous locations; 
Integrated design, simple and reasonable structure, can directly replace ordinary assembly type thermocouple, RTD; 
Thermocouple temperature change will be exempted from compensating cables, reduce costs; 
LCD, LED, and other indicator pointer timely and convenient on-site monitoring;
