儀表的分類方法很多，根據(jù)不同的原則可以分為許多類： </p> <p> <p> (1)檢測(cè)儀表的分類 </p> <p> 根據(jù)其檢測(cè)被測(cè)量的不同分為：溫度檢測(cè)儀表、壓力檢測(cè)儀表、流量檢測(cè)儀表、物位檢測(cè)儀表、分析儀表。 </p> <p> (2)顯示儀表的分類 </p> <p> 根據(jù)記錄、指示、模擬和數(shù)字等功能的不同分為：記錄儀表、指示儀表、模擬儀表、數(shù)顯儀表。 </p> <p> (3)在自控儀表的校準(zhǔn)、維修、安裝過程中，有些儀表稱為一次儀表，有些儀表稱為二次儀表。 </p> <p> 一次儀表是指安裝在現(xiàn)場(chǎng)且直接與工藝介質(zhì)相接觸的儀表，如壓變，溫變等。熱電阻、熱電偶一般不稱其為儀表，而稱為感溫元件。實(shí)際應(yīng)用中我們把安裝在現(xiàn)場(chǎng)的儀表(個(gè)別除外，如電動(dòng)閥門定位器)統(tǒng)稱為一次儀表。 </p> <p> 二次儀表是指儀表示值信號(hào)不直接來自工藝介質(zhì)的各類儀表的總稱，其信號(hào)通常來自一次儀表的傳送信號(hào)。二次儀表通常安裝在值班室內(nèi)的儀表盤上。 </p> <p> 儀表分類只是為儀表維修、維護(hù)、安裝及管理上方便，如何進(jìn)行分類及稱謂還要根據(jù)實(shí)際情況而定。 </p> </p><div

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)。 </p> <p> 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。 </p> <p> 在工業(yè)過程控制與技術(shù)測(cè)量過程中，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越***的應(yīng)用。 </p><div
