Abstract

Abstract: The temperature and pressure parameter simulation analysis and experimental research on the SMD pressure transducer temperature characteristics calibration device have been carried out.The results show that under the absolute pressure of 2 kPa and 500 kPa pressure points,the temperature distribution of the calibration chamber and pressure pipeline of the chip pressure sensor in the temperature range of -50 ℃~100 ℃ meets the requirements for use.The temperature isolation is achieved between the standard pressure source and the high and low temperature calibration chamber.The accuracy of the standard pressure value is ensured when calibrating the temperature response characteristics of the SMD pressure sensor.

Key words: SMD pressure sensor, Calibration chamber, Pressure pipeline, Temperature
