儀表以一般壓力表、耐震壓力表為主體，內(nèi)部加設(shè)記憶針裝置組成。 </p> <p> 儀表使用前先將記憶針調(diào)節(jié)到零位，在使用中壓力上升時，紅色記憶針會跟隨壓力指示針的運動而運動，指示出曾出現(xiàn)的壓力值。 </p> <p> 儀表使用條件：與選用的原各型壓力表相同。 </p> <p> 外形尺寸：與選用的原各型壓力表相同。 </p> <p> 普通不銹鋼壓力表，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。該系列儀表主要應(yīng)用于礦山、石油、化工、冶煉、電力、食品、醫(yī)藥、航天等行業(yè)。 </p> </p><p> 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><div

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)。樂山壓力儀表價格</p><p style="text-indent:25px">樂山壓力儀表價格</p><p> 電容式壓力傳感器 </p> <p> 它一般采用圓形金屬薄膜或鍍金屬薄膜作為電容器的一個電極，當薄膜感受壓力而變形時，薄膜與固定電極之間形成的電容量發(fā)生變化，通過測量電路即可輸出與電壓成一定關(guān)系的電信號。電容式壓力傳感器屬于極距變化型電容式傳感器，可分為單電容式壓力傳感器和差動電容式壓力傳感器。 </p> <p> <p> 應(yīng)變式壓力傳感器 </p> <p> 應(yīng)變式壓力傳感器是壓力傳感器中應(yīng)用比較多的一種傳感器，它一般用于測量較大的壓力，廣泛應(yīng)用于測量管道內(nèi)部壓力、內(nèi)燃機燃氣的壓力、壓差和噴射壓力、發(fā)動機和導(dǎo)彈試驗中的脈動壓力，以及各種領(lǐng)域中的流體壓力等。 </p> 樂山壓力儀表價格</p> <br /><p
