一种高温性能良好的GGY—2型高温光纤压力传感器已由南京航空学院研制成功,于最近通过了部级技术鉴定。鉴定组的专家认为,这种传感器在国内处于领先地位,达到90年代初国际先进水平。 该传感器具有良好的高温性能,在非冷却情况下,可以直接测量气体温度为300℃的动态压力;在冷却情况下,可以测量1700～1800℃燃气的脉动压力,非常适用于压气机失速喘振时压力变化过程、航空发动机燃烧室压力的测试,在内燃机、压缩机等高温气流动态压力的测试中也具有很大的实用价值。这种技术上先进的高温动态压力传感器,灵敏度高,工作频率范围宽,精度高,安装使用方便,
A good high-temperature performance GGY-2-type high-temperature optical fiber pressure sensor has been successfully developed by Nanjing Institute of Aviation, recently passed the ministerial technical appraisal. Identification group of experts believe that this sensor is in a leading position in the country, reached the early 90s international advanced level. The sensor has good high temperature performance and can directly measure the dynamic pressure of the gas at 300 ℃ under non-cooling conditions. When cooling, it can measure the pulsating pressure of the gas at 1700-1800 ℃, which is very suitable for the compressor stalling surge When the pressure change process, the test of the pressure of the combustion chamber of the aeroengine also has great practical value in the test of the dynamic pressure of the high-temperature airstream such as an internal combustion engine and a compressor. This technologically advanced high temperature dynamic pressure sensor, high sensitivity, wide operating frequency range, high precision, easy installation and use,
