style="text-indent:25px">一體式超聲波物位計是zui新專業(yè)制造的通用型超聲波物位計，它博采眾長，吸取了國內(nèi)外多種物位儀優(yōu)點，實現(xiàn)了全數(shù)字化，人性化設計理念，具有完善的物/液位測控·數(shù)據(jù)傳輸和人機交流功能。主芯片采用進口工業(yè)級單片機，數(shù)字溫度補償和超寬電壓輸入穩(wěn)壓等數(shù)十塊相關**集成電路。具有抗干擾性強，可任意設置上下限節(jié)點及在線輸出調(diào)節(jié)，并帶有現(xiàn)場顯示，可選擇模擬量，開關量及RS485輸出，方便的與相關設施接口。它不必接觸工業(yè)介質就能滿足大部分物位測量要求，從而徹底地解決了壓力式、電容式、浮子式等傳統(tǒng)測量方式帶來的纏繞，西安靜壓型物位計、堵塞、泄露，西安靜壓型物位計、介質腐蝕、維護不便等缺點。棒式，西安靜壓型物位計，用于測量液體介質或重量輕的固體介質，量程可達6米。西安靜壓型物位計</p><div style="width:100%;text-align: center;"><img style="max-width: 640px; max-height: 320px;" alt="西安靜壓型物位計,物位計" src="https://tyunfile.71360.com/WaterMark/UploadFile/xalunqian/637333661295029297/6878386.png"></div><p> 超聲波物位計主要的安裝方式有兩種，一個是頂部安裝，一個是底部安裝，超聲波物位計采用的也是液體導聲，超聲探頭安裝在料罐底部外，超聲波從底部傳入，經(jīng)被測液體傳播到液面，反射后傳回探頭。傳播時間與液位的高低成正比。微波物位計以光速傳播，速度幾乎不受介質特性的影響，傳播衰減也很小，約0.2dB/km.回波信號強弱很大程度上取決于被測液面上的反射情況。在被測液面上的反射率除了取決于被測物料的面積和形狀外，主要取決于物料的相對介電常數(shù)εr.相對介電常數(shù)高，反射率也高，得到的回波強度高;相對介電常數(shù)低，物料會吸收部分微波能量，回波強度較低。甘肅桿式導波雷達物位計儀表可以空倉調(diào)試。在固體測量中的應用可以使用K-頻段的高頻傳感器。</p><div style="width:100%;text-align: center;"><img style="max-width: 640px; max-height: 320px;" alt="西安靜壓型物位計,物位計" src="https://tyunfile.71360.com/WaterMark/UploadFile/xalunqian/637333661851611328/5177133.png"></div><p> 想知道導波雷達物位計正確安裝與使用，我們就得先了解它的工作原理和組成部分。 </p> <p> 導波雷達物位計它的測量原理是：裝置的電子部件發(fā)射的高頻微波脈沖沿著一根鋼纜運行，當接觸到煤粉表面，微波脈沖被反射回來，通過電子部件計算微波的運行時間，并輸出一個距離值。它的技術是目前國內(nèi)的優(yōu)越水平，然而在現(xiàn)場使用中，由于粉倉環(huán)境的復雜性和各方面的影響，使得其測量值往往存在誤差和虛假值，所以合理地安裝并正確地調(diào)試，使其測量穩(wěn)定，并使測量誤差在＜±1%范圍內(nèi)，是很重要的。導波雷達物位計的組成它由三部分組成：1，作為測量探頭的鋼纜及其過程連接件，2、用于把物位信號轉換為4—20mA信號的電子部件3、用于設置和顯示內(nèi)部參數(shù)的調(diào)整模塊PLICSCOM，4、顯示測量值的二次儀表。 </p><p> 重錘式料位計：優(yōu)點：測量不受介質密度、顆粒大小的影響。缺點：機械內(nèi)部易落灰塵影響測量效果；機械磨損較嚴重，需經(jīng)常維護，花費較大；重錘易發(fā)生被物料埋住現(xiàn)象，發(fā)生掉錘頭、斷帶故障。 </p> <p> 超聲波物位計：優(yōu)點：安裝方便，性能穩(wěn)定，測量精度高，價格低廉。缺點：對溫度，粉塵，蒸汽，壓力的影響比較敏感。 </p> <p> 雷達物位計：優(yōu)點：安裝方便，性能穩(wěn)定，測量精度高。對溫度，壓力的影響不敏感，可以用來連續(xù)測量腐蝕性液體、高黏度液體和有毒液體的液位。它沒有可動部件、不接觸介質、沒有測量盲區(qū),而且測量精度幾乎不受被測介質的溫度、壓力、相對介電常數(shù)的影響,在易燃易爆等惡劣工況下仍能應用。缺點：價格高昂，低頻的雷達體積龐大。對射頻干擾的影響明顯。對被測介質的介電常數(shù)有要求。對粉塵和蒸汽的影響和超聲是一樣的。天線容易積灰，影響測量阻旋物位計具有耐高溫，測量結果準確，抗干擾強等特點，他具有防抖性能，防塵密封性能和較高的性價比。</p><div style="width:100%;text-align: center;"><img style="max-width: 640px; max-height: 320px;" alt="西安靜壓型物位計,物位計"

超聲波液位計用途：液位和料位測量是工業(yè)上經(jīng)常遇到的一個問題，超聲測位技術有很多優(yōu)點，它不*能定點和連續(xù)測位，而且能方便的提供遙測或遙控所需的信號。與放射性測位技術相比，超聲技術不需要防護，與激光測距技術相比，它又有簡單和經(jīng)濟的優(yōu)點，同時超聲技術一般不需要運動部件，所以在安裝和維護上又相應比較方便。超聲波物位計可廣泛應用于石油、礦業(yè)、發(fā)電廠、化工廠、水處理廠、污水處理站、農(nóng)業(yè)用水、環(huán)保監(jiān)測、食品（釀酒業(yè)，飲料業(yè)、添加劑、食用油、奶制品）、抗洪防汛、水文監(jiān)測、明渠、空間定位等許多行業(yè)。超聲波物位計原理：物位測量過程中，超聲波信號由超聲波探頭發(fā)出，經(jīng)液體或固體物料表面反射后折回，由同一個探頭接收，測量超聲波的整個運行時間，從而實現(xiàn)物位的測量。聲波傳輸距離與聲速和聲傳輸時間的關系可用公式表示：超聲波物位計的算式L：超聲波探頭距所測料面距離。單位：m；v：經(jīng)溫度補償后的聲速值。單位：m/s；t：測量范圍內(nèi)聲波的運行時間。如果只對物料高度是否到達某一位置進行檢測稱為限位測量。完成這種測量任務的儀表叫做物位計。甘肅桿式導波雷達物位計</p><p

低介電常數(shù)和變介電常數(shù)的被測介質，推薦導波雷達。低介電常數(shù)液體介質反射信號弱，信號衰減嚴重，物位波動和泡沫散射引起信號減弱，罐內(nèi)障礙物反射引起虛假信號，為此就需要發(fā)射較強的電磁波信號，并采用功能強的微處理器進行復雜的信號處理。這就使得常規(guī)交流供電雷達物位計價格非常昂貴，但仍難以較好的解決在上述條件下的物位測量問題。導波雷達和常規(guī)雷達一樣，采用傳輸時間來測量介質物位，信號自烴類[介電常數(shù)2~3]液體表面或自水[介電常數(shù)80]面反射回傳的時間一樣的，不同的只是信號幅度[強度]的差別。普通雷達須考慮介質的影響，比較難辯識返回的各種信號，從雜散信號中檢出真正的物位信號，而導波雷達*需測量電磁波的傳輸時間即可，無需信號的處理和辨別。西安靜壓型物位計</p></p><br
