工作原理working principle
过程压力通过两侧或一侧的隔离膜片、灌充液传至δ室的中心测量膜片。中心膜片是一个张紧的弹性元件,
process pressure through tow sides or one side separate diaphragm, filled liquid transmit to centermeasuring diaphragm of chamber. center diaphragm is a stretch flexibility element. when it arises pressure on
the sides, it will has relevant displacement, the displacement and the differential pressure are direct ratio.
它对于作用在其上的两侧压力差产生相应变形位移,其位移与差压成正比,Zui大位移约 0. 1 mm ,这种位移转变为电容极板上形成的差动电容,由电子线路把差动电容转换成二线制的4 ~ 20ma dc 输出信号 。(见图1)
