壓力表中壓力的概念這里的壓力概念，實(shí)際上指的是物理學(xué)上的壓強(qiáng)，即單位面積上所承受壓力的大小。***壓力：以***壓力零位為基準(zhǔn)，高于***壓力零位的壓力。正壓：以大氣壓力為基準(zhǔn)，高于大氣壓力的壓力。負(fù)壓（真空）：以大氣壓力為基準(zhǔn)，低于大氣壓力的壓力。差壓：兩個(gè)壓力之間的差值。表壓：以大氣壓力為基準(zhǔn)，大于或小于大氣壓力的壓力。壓力表：以大氣壓力為基準(zhǔn)，用于測(cè)量小于或大于大氣壓力的儀表。2壓力表在工業(yè)過(guò)程控制與技術(shù)測(cè)量過(guò)程中，由于機(jī)械式壓力表的彈性敏感元件具有很高的機(jī)械強(qiáng)度以及生產(chǎn)方便等特性，使得機(jī)械式壓力表得到越來(lái)越***的應(yīng)用。機(jī)械壓力表中的彈性敏感元件隨著壓力的變化而產(chǎn)生彈性變形。機(jī)械壓力表采用彈簧管（波登管），膜片，膜盒及波紋管等敏感元件并按此分類。所測(cè)量的壓力一般視為相對(duì)壓力。一般相對(duì)點(diǎn)選為大氣壓力。彈性元件在介質(zhì)壓力作用下產(chǎn)生的彈性變形，通過(guò)壓力表的齒輪傳動(dòng)機(jī)構(gòu)放大，壓力表就會(huì)顯示出相對(duì)于大氣壓的相對(duì)值（或高或低）。在測(cè)量范圍內(nèi)的壓力值由指針顯示，刻度盤的指示范圍一般做成270度。3壓力表的分類壓力表按其測(cè)量精確度，可分為精密壓力表、一般壓力表。精密壓力表的測(cè)量精確度等級(jí)分別為、、、。膜盒表用的符號(hào)是kpa.河南全不銹鋼膜盒壓力表檢測(cè)</p><p
