IP67 Stainless Steel Industrial Temperature Sensor K Type Thermocouple

China Manufacture High Quality Low Quality Temperature Sensor 10*150mm Thermocouple

TY-S series thermocouple is used as a temperature sensor, usually in combination with display instruments, recording instruments and electronic regulators. It can directly measure the surface temperature of -50-600°C of liquid, steam, gas and solid surface in production processes.

Working principle

TY-S series thermocouple is composed of two different conductor materials. The temperature difference between the measuring terminal and the reference terminal will result in thermoelectric potential, and the working instrument will display the corresponding temperature value.

1. The structure principle of thermocouple

The industrialthermocouple is mainly composed of junction box, protective tube, terminal block, insulating ceramic column and temperature sensing element, and equipped with various installation and fixing devices.

1.1 ype of thermocouple: platinum rhodium 30-platinum rhodium 6, platinum rhodium 10-platinum, nickel chromium-nickel silicon, nickel chromium-copper nickel.

1.2 Protective tube: According to the type of thermocouple, the condition of the measured medium and the temperature to be measured, the tubes made of different materials are selected. The tubes of thermocouple are generally made of carbon steel, various grades of stainless steel, alloy steel and other materials.

1.3 Junction box: The junction box of thermocouple is used to connect the display instrument of temperature sensing element, generally made of aluminum alloy and stainless steel. It is divided into explosion-proof, waterproof and small splash-proof structures.

1.4 Wiring board: The wiring board of thermocouple is generally made of ceramics and installed in the junction box. It is the signal output terminal of the thermocouple, and divided into two types: single-branch type and double-branch type.

1.5 Installation and fixing device: The installation and fixing device is for users to install and fix thermocouple. It is divided into various forms, such as no fixing device, fixed thread, movable flange and fixed flange.

1.6 Nominal pressure

Generally it refers to the static external pressure that the tube can withstand without breaking under the working temperature. In fact, it is not only related to the tube material, diameter, and wall thickness, but also related to the structure, installation method, insertion depth, and the flow rate and type of the medium to be measured.
