摘要
针对目前尚无人对数字式气压计检定箱技术性能的测试方法进行过研究,研究制定出了一套科学合理的数字式气压计检定箱技术性能测试方案,包括对测试所选用测量设备技术指标的要求、测试所需环境条件及传压介质的要求、测试气路连接方式的要求、各项技术性能测试方法的设计及测试结果的验证,并以控制范围为(440~1100)hPa的QYJD-10型气压检定箱作为测试对象,以测量范围为(500~1100)hPa的0.01级数字式气压计作为气压标准器、以测量范围为(-60~81)℃和最大允许误差为±0.05℃的数字温度计作为温度标准器,对该测试方案进行了测试验证,综合评价了气压检定箱的各项技术性能均符合被检定或校准仪器相应规程规范的要求,从而证明了该测试方案具有合理性与可行性,为数字式气压计检定箱技术性能的测试工作提供一定的技术指导。
At present,no one has studied the test method of the technical performance of the digital barometer test box,and a scientific and reasonable technical performance test scheme of digital barometer test box is developed.Including the requirements for the technical indicators of the selected measuring equipment,the requirements for the required environmental conditions and the pressure transmission medium,the requirements for the test air circuit connection mode,the design of various technical performance test methods and the verification of the test results and Taking QYJD-10 pneumatic test box with control range(440~1100)hPa as the test object,take 0.01 level digital barometer with measuring range(500~1100)hPa as pressure standard,digital thermometer with measuring range(-60~81)℃and digital thermometer with maximum allowable error of±0.05℃as temperature standard,the test protocol was test-verified,comprehensive evaluation of the technical performance of the pneumatic test box are in line with the requirements of the verification or calibration instruments,thus to prove that the test scheme is reasonable and feasible,it provides certain technical guidance for the technical performance test of the digital barometer test box.
