Background

The thermocouple is a commonly used temperature measuring element in a temperature measuring instrument, directly measures temperature, converts a temperature signal into a thermal electromotive force signal, and converts the thermal electromotive force signal into the temperature of a measured medium through an electric instrument (a secondary instrument). The appearance of various thermocouples is very different according to needs, but the basic structures of the thermocouples are almost the same, and the thermocouples are generally composed of main parts such as a thermode, an insulating sleeve protection tube, a junction box and the like, and are generally matched with a display instrument, a recording instrument and an electronic regulator for use.

The temperature transmitter on the existing thermocouple is directly placed or bonded in the junction box, the transmitter is placed to shake in the junction box for a long time to lead to the loosening of a wire end, the temperature transmitter can fall off after bonding for a long time, the thermocouple is connected to a measured object through threads during installation, and the thermocouple shell can deform due to the fact that the thermocouple is longer and directly screwed.
