A typical thermocouple is comprised of metal or ceramic protection tube in which the thermoelectric elements are embedded with beaded ceramic insulators.
Thermocouples are used to measure the temperature of many gases and liquids. If the wire is used directly with bare wires, the wire will be subjected to mechanical and scientific actions from the outside, resulting in remarkable deterioration and a shorter service life. Therefore, the wire should be placed in an insulation tube or protective tube.
It is important to select the most suitable insulation and protection tubes in consideration of the conditions of the place of use, and this is an important point of temperature measurement technology.
