Design and Optimization of Automatic Calibration System for Temperature Resistance Relationship
Aiming at the problems of low automation,long time and insufficient precision in the temperature and temperature rise measurement of Pt 100 and thermistor,this paper studies the resistance value-temperature rela-tionship of Pt 100 and the resistance value change of thermistor-temperature rise relationship,develops a set of temperature calibration method,and designs and builds a temperature calibration system.At the same time,com-bined with the calibration method and calibration requirements,the automatic calibration and data processing pro-gram is developed.The results show that the system can realize automatic operation,improve the calibration effi-ciency and accuracy,meet the high precision calibration requirements of thermometer,and provide a multi-type,multi-temperature point cross-calibration automatic control calibration scheme.
