摘要
设计了一套在超低温环境下对压力传感器进行测试和标定的校验装置,并且成功地在-253~-163℃、0~2MPa压力范围内对自行研制的超低温压力传感器进行了标定。
A calibration device for testing and calibrating pressure sensors at ultra-low temperature was de- signed and applied to calibrating self-developed ultra-low temperature pressure sensor at -253 - -163℃ and 0 - 2MPa successfully.
