On the industrial production site, the operational accuracy of thermocouple calibration is directly related to the stability of the production process. Firstly, thorough preparation is essential. Check the appearance of the thermocouple for any signs of damage or corrosion, which not only affects the calibration accuracy but also concerns the safety of the equipment. Clean the measuring end to ensure it can accurately sense the temperature and avoid interference from impurities in the generation of thermoelectric potential. Meanwhile, the instruments and meters used for calibration, such as standard thermometers and potentiometers, need to be preheated and calibrated to zero in advance to ensure a reliable measurement benchmark.
During the operation, temperature control is a crucial step. According to the type of thermocouple and the temperature range to be measured, select appropriate heating or cooling equipment and precisely control the heating and cooling rates to avoid irreversible effects on the characteristics of the thermocouple due to thermal shock. When reading the thermoelectric potential data, the operator should keep the environment quiet to reduce electromagnetic interference, record the data accurately after the values stabilize, and take the average of multiple measurements to reduce random errors, ensuring the high quality of on-site calibration data and laying a solid foundation for precise temperature control in the production process.
