由航空工业部611研究所与扬州无线电二厂联合研制的卡式无损伤压力传感测试系统,于85年12月26日在扬州通过技术鉴定,并投入小批量生产。此系统由YE5960差动式数字压力测试仪和YE14204型卡式无损测压传感器所组成。该系统采用“管壁测压法”的原理,从而打破了传统的测压方法,使系统具有以下的特点: 1、采用卡式传感器在管外测压,这样能保持管内流场,能真实测得管内压力和静、动态特
The card-type non-destructive pressure sensing test system jointly developed by Institute of Aeronautics and Astronautics 611 and Yangzhou Radio No.2 Factory passed the technical appraisal in Yangzhou on December 26, 1985 and was put into small batch production. This system consists of YE5960 differential digital pressure tester and YE14204 type card non-destructive pressure sensor. The system uses the principle of “wall pressure measurement”, thus breaking the traditional pressure measurement method, the system has the following characteristics: 1, the use of card-type pressure sensor outside the tube, so to maintain the flow field inside the tube, can be true Measured tube pressure and static and dynamic special
