2、壓力的兩種表示方法： </p> <p> ***壓力：以***真空為基準，高于***真空的壓力； </p> <p> 相對壓力：以大氣壓力作為基準所標示的壓力。 ***壓力=大氣壓力+相對壓力 </p> <p> 壓力表的知識： </p> <p> 1、概念：以大氣壓力為基準，用于測量小于或大于大氣壓力的儀表。 </p> <p> A、壓力表按其測量精確度，可分為精密壓力表、一般壓力表； </p> <p> B、壓力表按其指示壓力的基準不同，分為一般壓力表、***壓力表、差壓表； </p> <p> C、壓力表按其測量范圍，分為真空表、壓力真空表、微壓表、低壓表、中壓表及高壓表； </p> <p> D、壓力表按其組成，液柱式，電子式和機械式。 </p><p> 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)檢測儀表的分類 </p> <p> 根據(jù)其檢測被測量的不同分為：溫度檢測儀表、壓力檢測儀表、流量檢測儀表、物位檢測儀表、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、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。實際應(yīng)用中我們把安裝在現(xiàn)場的儀表(個別除外，如電動閥門定位器)統(tǒng)稱為一次儀表。 </p> <p> 二次儀表是指儀表示值信號不直接來自工藝介質(zhì)的各類儀表的總稱，其信號通常來自一次儀表的傳送信號。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、安裝及管理上方便，如何進行分類及稱謂還要根據(jù)實際情況而定。 </p> </p><div style="width:100%;text-align: center;"><img
