Abstract: In order to ensure the accuracy of the measurement data,it is necessary to calibrate the temperature-response characteristics parameters of the pressure sensor under high and low temperature environment.The temperature-response characteristics calibration device for the pressure sensors is developed by designing systems such as the standard pressure sources,the temperature isolation units,and the multi-point temperature measurement calibration chambers.The calibration of the pressure sensors,within the pressure range of absolute pressure 2~500 kPa and under the ambient temperature conditions of -50 ℃~100 ℃,is realized.The measurement uncertainty of the calibration device is better than 0.05% (k=2),laying the foundation for conducting research on the temperature response characteristics of pressure sensors.
