【摘要】 本文给出了一种光纤复合压力计。该压力计在原有的C型弹簧管机械压力表的基础上,复合了一个光纤传感装置。这种压力计扩展了原机械压力表的功能,特别适合于易燃易爆的石油、化工等场合的压力遥测。测试结果表明,该光纤复合压力计不仅具有良好的重复性,还能自动消除光源强度变化对测量结果的影响。更多还原

【Abstract】 A fiber-optic mechanical compound manometer is introduced inthis paper. The compound manometer consists of a C-type spring tubemanometer and an optical fiber sensing device. In this way, themanometer functions are developed and it is suitable for remote thepressure of the store tanks of oil or chemical goods espeeially, becausethese places are easy to fire and to explode. The testing results shownthat thes compound manometer not only has good repeatability, but alsocan eliminate the effect on measuring result caused by the variation ofthe light source intensity.更多还原
