Thermocouple Ceramic Tube

The thermocouple ceramic tubes have high temperature resistance, corrosion resistance, excellent thermal shock resistance, low thermal expansion coefficient and good thermal conductivity, thus ensuring the stable use of thermocouples as temperature-sensitive components in the fields of industrial production and scientific research.

As we all know, with the advancement of science and technology, temperature measurement technology has developed rapidly. Thermocouple has become the most widely used temperature sensing element in the fields of industrial production and scientific research because of its stable performance, accuracy and reliability, simple structure, convenient use, wide temperature measurement range, and remote signal transmission. In its temperature measurement process, the thermocouple protection sleeve plays an important role. The performance of the casing material affects the long-term stability and service life of the thermocouple and other performance indicators. Especially thermocouples that work at high temperatures have higher requirements for their materials. For example, for continuous temperature measurement of molten steel, the thermocouple protection tube not only has to withstand high temperatures, but it is also corroded and impacted by hot molten steel. When measuring the temperature in a circulating fluidized bed boiler, there are not only high temperature oxidation and high temperature corrosion, but also high temperature erosion wear of fluid powder. Such a harsh working environment is a severe test for the protective casing material. The emergence of ceramic tubes for thermocouple provides a new and better choice for this industrial application.
