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。 一、結(jié)構(gòu)原理 儀表由測量系列(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),具有較好的密封性,能保護內(nèi)部機構(gòu)不受污穢。 儀表的作用原理是基于彈性元件(測量系統(tǒng)上的膜片)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將被測值在度盤上指示出來。 二、主要技術(shù)指標(biāo) 三、型號標(biāo)示及參考價格 壓力表 | 表殼外徑 | 類型 | 參考價格(元) |
