zui低料位也就是使超聲波能到達(dá)的距離傳感器的zui遠(yuǎn)距離，并且使反射回波能被傳感器接收。由于超聲波在傳播過(guò)程中的衰減以及物料表面對(duì)聲波的吸收，這一傳播距離對(duì)物料性質(zhì)依賴(lài)性很強(qiáng)，對(duì)于DU33來(lái)說(shuō)，可測(cè)液體范圍為25m，固體范圍為15m。 </p> <p> 總之，只要儀表選型、安裝適當(dāng)，超聲波物位計(jì)的應(yīng)用效果還是比較滿意的。 </p> <p> 超聲波類(lèi)儀表(超聲波流量計(jì))是現(xiàn)代科學(xué)技術(shù)在工業(yè)測(cè)量中的具體運(yùn)用，是高新電子技術(shù)和聲學(xué)原理相結(jié)合的產(chǎn)物。比起常規(guī)儀表，它們的智能化更高，應(yīng)用的技術(shù)更先進(jìn)，也給用戶(hù)帶來(lái)更大方便。 </p><p style="text-indent:25px">射頻導(dǎo)納物位計(jì)的測(cè)量原理：射頻導(dǎo)納是一種從電容式發(fā)展起來(lái)的、防掛料、更可靠、更準(zhǔn)確、適用性更廣的新型物位控制技術(shù)，是電容式物位技術(shù)的升級(jí)。所謂射頻導(dǎo)納，導(dǎo)納的含義為電學(xué)中阻抗的倒數(shù)，它由電阻性成分、電容性成分、感性成分綜合而成，而射頻即高頻無(wú)線電波譜，所以射頻導(dǎo)納可以理解為用高頻無(wú)線電波測(cè)量導(dǎo)納。儀表工作時(shí)，儀表的傳感器與灌壁及被測(cè)介質(zhì)形成導(dǎo)納值，物位變化時(shí)，導(dǎo)納值相應(yīng)變化，電路單元將測(cè)量導(dǎo)納值轉(zhuǎn)換成物位信號(hào)輸出，實(shí)現(xiàn)物位測(cè)量。對(duì)于常用的圓錐形喇叭天線來(lái)說(shuō)，微波的頻率越高，波束的聚焦性能越好。</p><div

1、通用性強(qiáng):可測(cè)量液位及料位，可滿足不同溫度、壓力、介質(zhì)的測(cè)量要求，比較高測(cè)量溫度可達(dá)800℃，比較大壓力可達(dá)5MPa，并可應(yīng)用于腐蝕、沖擊等惡劣場(chǎng)合。 </p> <p> 2、防掛料:獨(dú)特的電路設(shè)計(jì)和傳感器結(jié)構(gòu)，使其測(cè)量可以不受傳感器掛料影響，無(wú)需定期清潔，避免誤測(cè)量。 </p> <p> 3、免維護(hù):測(cè)量過(guò)程無(wú)可動(dòng)部件，不存在機(jī)械部件損壞問(wèn)題，無(wú)須維護(hù)。 </p> <p> 4、抗干擾:接觸式測(cè)量，抗干擾能力強(qiáng)，可克服蒸汽、泡沫及攪拌對(duì)測(cè)量的影響。 </p> <p> 5、準(zhǔn)確可靠:測(cè)量量多樣化，使測(cè)量更加準(zhǔn)確，測(cè)量不受環(huán)境變化影響，穩(wěn)定性高，使用壽命長(zhǎng)。高頻的調(diào)頻雷達(dá)技術(shù)尤其適合大型固體料倉(cāng)的物位測(cè)量!寧夏拋物面高頻雷達(dá)物位計(jì)價(jià)格</p><p style="text-indent:25px">接觸式微波物位計(jì)一般采用金屬波導(dǎo)體(桿或鋼纜)來(lái)傳導(dǎo)微波，儀表從倉(cāng)頂安裝，導(dǎo)波桿直達(dá)倉(cāng)底。寧夏拋物面高頻雷達(dá)物位計(jì)價(jià)格</p><p> 超聲波物位儀是由微處理器控制的數(shù)字液位儀表。在測(cè)量中脈沖超聲波由傳感器發(fā)出，聲波經(jīng)液體表面反射后被同一傳感器接收并轉(zhuǎn)換成電信號(hào)。一體式防爆超聲波液位計(jì)具有自動(dòng)功率調(diào)整，溫度補(bǔ)償，抗干擾等功能。一體式防爆超聲波液位計(jì)由于采用非接觸測(cè)量，被測(cè)介質(zhì)幾乎不受控制，可用于強(qiáng)腐蝕性介質(zhì)。防爆超聲波物位儀可采用二線制、三線制或四線制技術(shù)，供電回路和信號(hào)輸出回路**，當(dāng)采用直流24v供電時(shí)，可使用一根3芯電纜線，供電負(fù)端和信號(hào)輸出負(fù)端共用一根芯線；當(dāng)采用交流220v供電時(shí)，或者當(dāng)采用直流24v供電，要求供電回路與信號(hào)輸出回路完全隔離時(shí)，應(yīng)使用一根4芯電纜線。直流或交流供電，具有4~20mADC，高低位開(kāi)關(guān)量輸出。寧夏拋物面高頻雷達(dá)物位計(jì)價(jià)格</p></p><br
