Challenges and Countermeasures of Temperature Calibration in Extreme Environments

Temperature calibration in extreme environments faces many challenges. In high - temperature environments, such as the furnaces in the metallurgical industry and the combustion chambers of aircraft engines, high temperatures not only affect the material properties of thermometers, reducing their measurement accuracy, but may also cause damage to the calibration equipment. To meet the high - temperature challenge, thermometers and calibration equipment made of special high - temperature - resistant materials are required, such as thermocouple thermometers made of materials like ceramics and tungsten - rhenium alloys. At the same time, effective heat - insulation and cooling measures need to be designed to ensure the normal operation of the calibration equipment in high - temperature environments.
In low - temperature environments, such as polar scientific research and low - temperature physics experiments, low temperatures can change the physical properties of some materials, affecting the sensitivity and accuracy of thermometers. In addition, calibration equipment in low - temperature environments also needs to consider issues such as antifreeze and moisture - proof. Using low - temperature thermometers based on special principles, such as silicon - diode thermometers, combined with specially designed low - temperature calibration devices, can achieve relatively accurate temperature calibration in low - temperature environments. At the same time, provide good insulation and protection for the calibration equipment to prevent equipment failures caused by low temperatures.
