弹簧管压力表是以弹簧管为敏感元件的压力测量仪表,其工作原理是:弹簧管在压力和真空作用下,产生弹性变形引起管端位移(S),其位移通过扇形齿轮传动机构进行放大,传递给指示装置,再由指针在刻有法定计量单位的分度盘上指出被测压力或真空值。在仪表中为了获得线性刻度,使读数方
Bourdon tube pressure gauge is a spring tube as a sensitive component of the pressure measuring instrument, the working principle is: the spring tube under pressure and vacuum, resulting in elastic deformation caused by the tube end displacement (S), the displacement through the sector gear transmission amplification , Passed to the indicating device, and then pointed by the pointer on the graduated engraved with the legal unit of measurement of the measured pressure or vacuum value. In order to get a linear scale in the meter, make the reading square
