Po,式中：P表示液位傳感器測量點直接接觸液面所受壓力， ρ表示被測液體的密度值，g表示重力加速度，寧夏小巧型壓力變送器介紹,Po是液面上大氣壓,H是傳感器投入液體的深度同時，通過導氣不銹鋼將液體的壓力引入到傳感器的正壓腔，再將液面上的大氣壓Po與傳感器的負壓腔相連，以抵消傳感器背面的Po，使傳感器測得壓力為：ρ，寧夏小巧型壓力變送器介紹.g.H，顯然,通過測取壓力P，可以得到液位深。 </p> <p> 2、液位測量法：液位測量方法可分為機械高度法和壓強測定法。機械高度：機械傳動結構復雜，器械的豎直度影響測量精度。并且是筆繪模擬曲線或人工讀數(shù)。壓強法：利用埋于液體底部或一定深度的壓力傳感器測定壓力，利用公式Pa=ρCH得到液位的高度。又可根據(jù)容器的結構設計尺寸得到相應高度的容器容量——所盛液體的體積。壓力傳感器輸出的是與壓力傳感器成正比的電信號，寧夏小巧型壓力變送器介紹，可以遠距離傳輸，并便于自動記錄和為處理器的修正、補償，進一步提高精度。 </p> <p> <br /> 壓力變送器把壓力信號傳到電子設備，進而在計算機顯示壓力。寧夏小巧型壓力變送器介紹</p><div style="width:100%;text-align: center;"><img style="max-width: 640px; max-height: 320px;" alt="寧夏小巧型壓力變送器介紹,壓力變送器"

style="text-indent:25px">在選用壓力變送器之初，要對現(xiàn)場使用工況進行分析，根據(jù)具體使用環(huán)境選擇適合的壓力變送器，還要采取適當?shù)拇胧?，減少環(huán)境對壓力變送器的影響。壓力變送器穩(wěn)定性有定量指標，在超過使用期后，需要重新進行標定，以確保壓力變送器的性能是否發(fā)生變化。在某些要求壓力變送器能長期使用而又不能輕易更換或標定的場合，所選用的壓力變送器穩(wěn)定性要求更嚴格，要能夠經(jīng)受住長時間的考驗。壓力變送器穩(wěn)定性有著重要的意義，選擇高穩(wěn)定性的壓力變送器是非常有必要的。在高穩(wěn)定性能這個基礎前提下，才能制造出具有高準確度、高可靠性等能力的壓力變送器。壓力變送器穩(wěn)定性對于生產(chǎn)的正常運行以及壽命的使用都有著重要的影響。陜西防腐壓力變送器介紹擴散硅壓力變送器高準確度、高穩(wěn)定性、選用進口原裝傳感器，線性好，溫度穩(wěn)定性高。</p><div

在壓力變送器的使用過程中需要電源為其供電，通常情況下我們?nèi)粘Ｉ钪杏玫降碾妷簽?20V的交流電（AC），對于壓力變送器而言，需要連續(xù)輸出穩(wěn)定的信號，直流電(DC)在方向和大小上都是穩(wěn)定的，不會隨時間發(fā)生改變，交流電則恰恰相反。這就是大多數(shù)壓力變送器采用直流電的原因。錯誤的選擇壓力變送器的供電電壓，會損壞壓力變送器的電路板，這也是導致壓力變送器出現(xiàn)故障的主要原因之一。采用多大的供電電壓是壓力變送器的一個重要的問題。 </p> <p> 壓力變送器的常規(guī)供電電壓為12～36V DC,采用此范圍的供電電壓可以有效的避免因電壓過高造成損壞，選擇此范圍的供電電壓也比較符合現(xiàn)在主流設備，方便壓力變送器與其它設備系統(tǒng)進行對接、組合使用。習慣上24V DC的供電電壓用在壓力變送器中應用的比較多， 24V DC能夠適應大多數(shù)傳輸和負載需求（帶 250Ω×2個負載和 1KM 傳輸距離），高了浪費低了應用受限制，當然如果有需要完全可以改變供電電壓。 </p> <p> <br /> </p> <p> <br /> </p> <p> <br /> 壓力變送器根據(jù)測量范圍可分成一般壓力變送器和微差壓變送器，負壓變送器三種。</p><div style="width:100%;text-align: center;"><img style="max-width:
