WRC-130 WRC2-130 WRC-131 WRC2-131 Assembly thermocouple

Overview of WRC-130 WRC2-130 WRC-131 WRC2-131 Assembly thermocouple

Assembled thermocouple is a sensor  that measures temperature, and is often used in conjunction with display instruments, recording instruments and electronic regulators. Form a process control system to directly measure or control the temperature of liquid, steam and gas media and solid surfaces in the range of 0℃-1800℃ in various production processes, simple assembly, easy replacement, compression spring temperature sensing element, anti-vibration Good performance, large measuring range, high mechanical strength, good pressure resistance, widely used in electric power, thermal power, metallurgy, medicine, chemical industry, machinery manufacturing and other industries.

Working principle of WRC-130 WRC2-130 WRC-131 WRC2-131 Assembly thermocouple

The assembled thermocouple is mainly composed of a junction box, a protection tube, an insulating sleeve, a connection terminal, a thermal electrode, and a compensation wire and several main installation devices. The compensation wire is a special wire used for signal transmission between the thermocouple and the secondary (base) instrument. It can eliminate the measurement error caused by the temperature change of the cold end of the thermocouple and ensure the accurate measurement of the medium temperature by the instrument. Use them to connect the thermocouple with the measuring device to compensate the error caused by the temperature change at the connection of the thermocouple. The compensation wire should be divided into two types: extension type and compensation type according to the material of the core alloy wire, and the insulating coating has Plastic, fluoroplastic, glass fiber and cable structure type with metal shielding, etc.

The thermoelectromotive force of the thermocouple will increase as the temperature of the measuring end increases. The size of the thermoelectromotive force is only related to the material of the thermocouple conductor and the temperature difference between the two ends, and has nothing to do with the length and diameter of the thermode. The assembled thermocouple is mainly composed of a junction box, a protective tube, an insulating sleeve, a terminal, and a hot electrode, and is equipped with various installation and fixing devices.
