在工業(yè)過程控制與技術(shù)測量過程中，由于機械式壓力表的彈性敏感元件具有很高的機械強度以及生產(chǎn)方便等特性，使得機械式壓力表得到越來越***的應(yīng)用。 </p> <p> 機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。所測量的壓力一般視為相對壓力。一般相對點選為大氣壓力。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機構(gòu)放大，壓力表就會顯示出相對于大氣壓的相對值(或高或低)。 </p><p> 計量檢定 </p> <p> 計量檢定是指為評定計量器具的計量性能，確定其是否合格所進行的全部工作，包括檢驗和加封蓋印等。它是進行量值傳遞的重要形式，是保證量值準確一致的重要措施。 </p> <p> 計量檢定按照管理環(huán)節(jié)的不同，可以分以下五種：周期檢定、出廠檢定、修后檢定、進口檢定、仲裁檢定。 </p> <p> 計量器具按照管理性質(zhì)的不同，可以分為強制檢定和非強制檢定，兩者又統(tǒng)稱為計量法制檢定。 </p> <p> 儀表性能指標 </p> <p> 檢測儀表中常用的基本性能包括測量范圍及量程、基本誤差、精度等級、靈敏度、分辨率、漂移、可靠性以及抗干擾性能指標等。 </p> <p> (1)測量范圍：是指該儀表按規(guī)定的精度進行測量的被測變量的范圍。 </p> <p> (2)量程：量程=測量上限值-測量下限值。 </p> <p> (3)零點遷移：是指零點的變化，而量程遷移是指量程的變化。 </p> <p> (4)靈敏度：反應(yīng)儀表對被測參數(shù)變化的靈敏程度，常以在被測參數(shù)改變時，經(jīng)過足夠時間儀表指示值達到穩(wěn)定狀態(tài)后，儀表輸出變化量與引起此變化的輸入量之比作為靈敏度。 </p> <p> (5)分辨率：又稱靈敏限，它是儀表輸出能響應(yīng)和分辨的**小輸入量，是靈敏度的一種反應(yīng)。 </p><div style="width:100%;text-align: center;"><img style="max-width: 640px; max-height: 320px;" alt="資陽壓力儀表廠家,壓力儀表" src="http://tyunfile.71360.com/UploadFile/cdwckj/637107306626250000/2926369.jpg"></div><p> 誤差的分類 </p> <p> ①***誤差：某被測量的儀表顯示值與約定真值之間的差值。 </p> <p> ②相對誤差：***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，被測量不變，計量器具正反行程不同時其示值之差。 </p> <p> ⑥精度：是衡量儀表測量數(shù)值精確度的重要指標，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、隨機誤差和粗大誤差等。 </p> <p> (1)準確度：測量中系統(tǒng)誤差的反映，表征測量結(jié)果偏離真實值的程度。 </p> <p> 通常認為，測量準確度是一個定性的概念，不宜將其定量化。例如，不宜說準確度為0．25%、16mg或±16mg等。在實際工作中，測量準確度可以用測量結(jié)果對約定真值的偏移來估計。南充壓力儀表推薦廠家</p><p style="text-indent:25px">資陽壓力儀表廠家</p><p
