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，瀘州壓力儀表推薦，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，瀘州壓力儀表推薦。 </p> <p> 儀表分類只是為儀表維修、維護(hù)，瀘州壓力儀表推薦、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>

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> <p> 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> AKK-EKA430A壓力變送器用于測(cè)量氣體、液體和蒸汽的壓力，然后將其轉(zhuǎn)變成4-20mADC的電流信號(hào)輸出。HAKK-EKA430A也可以通過BRAIN手操器或CENTUM CS/μXL或HART375手操器相互通訊，通過它們進(jìn)行設(shè)定和監(jiān)控等。 </p> <p> 耐震不銹鋼壓力表，該系列儀表全部采用有良好耐腐蝕性能的不銹鋼材質(zhì)制造，主要零件采用1Cr18Ni9、OCr18Ni12Mo2Ti、USU316、USU316L等材料，適用于有腐蝕性的環(huán)境，可檢測(cè)有弱腐蝕性，但不結(jié)晶、不凝固、粘度低的液體、氣體或蒸汽等介質(zhì)的壓力。 </p><div style="width:100%;text-align:

①***誤差：某被測(cè)量的儀表顯示值與約定真值之間的差值。 </p> <p> ②相對(duì)誤差：***誤差與約定真值的百分比。 </p> <p> ③引用誤差：***誤差與儀表滿量程的百分比。 </p> <p> ④比較大引用誤差：比較大***誤差與量程的百分比。 </p> <p> ⑤回程誤差：相同條件下，被測(cè)量不變，計(jì)量器具正反行程不同時(shí)其示值之差。 </p> <p> ⑥精度：是衡量?jī)x表測(cè)量數(shù)值精確度的重要指標(biāo)，用比較大引用誤差去掉“±”和“%”表示，其序列為0．005、0．02、0．05、0．1、0．2、1．0、1．5、2．5等。 </p> <p> 誤差分析基礎(chǔ) </p> <p> 誤差可分為系統(tǒng)誤差、隨機(jī)誤差和粗大誤差等。 </p> <p> (1)準(zhǔn)確度：測(cè)量中系統(tǒng)誤差的反映，表征測(cè)量結(jié)果偏離真實(shí)值的程度。 </p> <p> 通常認(rèn)為，測(cè)量準(zhǔn)確度是一個(gè)定性的概念，不宜將其定量化。例如，不宜說準(zhǔn)確度為0．25%、16mg或±16mg等。在實(shí)際工作中，測(cè)量準(zhǔn)確度可以用測(cè)量結(jié)果對(duì)約定真值的偏移來估計(jì)。瀘州壓力儀表批發(fā)</p><p
