中国建筑科学院钨弦式土压力仪鉴定会于81年8月6日至8日在北京召开,该仪器采用调频型钨弦传感元件,灵敏度高,稳定性好。压力盒采用活塞双膜传压结构,量测结果不因介质不同而有差异。仪器采用了介调线路、触发装置适于自动检测猝发随机动土压力。仪器曾在国防、煤矿、铁路、桥梁等工程试用,性能良好,达到预期效果。因此,鉴定会认为该仪器在同类产品中具有国内先进水平,可投入小批量生产。
China Academy of Building Tungsten Oxidation of soil pressure instrument identification will be August 6, 2001 to 8 held in Beijing, the instrument uses FM-type tungsten-chord sensor, high sensitivity, good stability. The pressure box uses the piston double membrane pressure transmission structure, the measurement result does not have the difference because of the medium different. The instrument uses a dielectric line, the trigger device is suitable for automatically detecting bursts random earth pressure. Instruments in national defense, coal, railways, bridges and other projects trial, good performance, to achieve the desired results. Therefore, the appraisal will think that the instrument has the advanced level in the same type of products and can be put into small batch production.
