High Stability and Accuracy K-type Thermocouple

K-type thermocouples are usually composed of thermocouples, insulating sleeves, protective tubes, junction boxes and other parts. The following is a detailed introduction to each part:Thermocouple: It is the core component of K-type thermocouples. It is composed of two metal wires of different components, usually nickel-chromium alloy (positive electrode) and nickel-silicon alloy (negative electrode). These two metals will produce different thermoelectric potentials at different temperatures, and the temperature is calculated by measuring the thermoelectric potential. The diameter of the thermocouple is generally between 0.25-2.5mm, and the length depends on the specific usage scenario. Insulating sleeve: It is used to isolate the two thermocouples to prevent short circuits between them, and also plays a role in protecting the thermocouples. Insulating sleeves are usually made of materials with high temperature resistance and good insulation performance, such as ceramics, quartz, etc.…
