The structure principle of armored thermocouple is: by the thermocouple effect, high purity magnesium oxide and small rust steel protection pipe through multiple composite drawing, with bending, high pressure resistance, shock resistance, thermal response time fast and durable and many other advantages, called to directly measure the temperature of liquid, gas medium and solid body surface in the range of 0~800℃ in various production processes

. If there is no special explanation, our company's standard products with a diameter of less than 8mm are Kaifu thermocouples.

The prefabricated thermocouple is mainly composed of junction box, protective tube, insulating sleeve, wiring terminal and thermal electrode, and is equipped with various mounting and fixing devices. Thermocouple commonly used compensation wire specifications

According to the temperature range applicable to the compensation wire, our company's standard products mainly use two kinds of compensation wire :PVC compensation wire and metal mesh compensation wire, of which PVC

Compensation wire core is multi-strand, soft texture, temperature resistance limit is 80; Metal mesh compensation wire core is a single strand penalty, anti-ten disturbance performance is good, the temperature limit is 400 temperature sensor selection: determine the thermocouple temperature sensor type, the actual use of temperature range, accuracy, size and installation fixing method, etc., according to the needs of reference and detailed selection data, also called according to the customer's drawings or sample processing customized.
