摘要
为确保测量数据的准确性,需对压力传感器在高低温环境下温度响应特性参数进行校准,通过开展标准压力源、温度隔离单元、多点测温校准腔等系统设计,研制了一套压力传感器温度响应特性校准装置,实现了在-50 ℃至100 ℃环境温度条件下,对绝压2～500 kPa范围内压力传感器校准,校准装置测量不确定度优于0.05％(A=2),为开展压力传感器温度响应特性研究奠定了基础.
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.
