膜片壓力表適用于測量具有一定腐蝕性、非凝固或非結(jié)晶的各種流體介質(zhì)的壓力或負壓。
耐腐蝕性能取決于膜片材料。 □結(jié)構(gòu)原理
儀表由測量系統(tǒng)(包括法蘭接頭、波紋膜片)、傳動指示機構(gòu)(包括連桿、齒輪傳動機構(gòu)、指針和度盤)和外殼(包括表殼和罩圈)等組成。儀表外殼為防濺結(jié)構(gòu)，具有較好的密性，故能保護其內(nèi)部機構(gòu)免受污穢浸入。
儀表的作用原理是基于彈性元件(測量系統(tǒng)上膜片)變形。在被測介質(zhì)的壓力作用下，迫使膜片產(chǎn)生相應(yīng)的彈性變形---位移，借助連桿組經(jīng)傳動機構(gòu)的傳動并予放大，由固定于齒輪上的指針逐將被測值在度盤上指示出來。
