Thermocouple quartz tubes are widely used for temperature measurement in harsh environments such as high temperature, corrosion, and vacuum, such as metallurgy, chemical industry, aerospace, nuclear energy, etc. In these fields, because the measured medium often has characteristics such as high temperature, high pressure, and strong corrosion, traditional temperature sensors are difficult to meet the requirements, and thermocouple quartz tubes have become the preferred temperature measurement element with their unique performance advantages.

It should be noted that during the use of thermocouple quartz tubes, it is necessary to protect its packaging structure to avoid damage caused by mechanical shock or vibration. At the same time, it is also necessary to select appropriate thermocouple materials and quartz tube materials according to the characteristics of the measured medium and the working environment to ensure the accuracy and reliability of the measurement.
