四、光電液位開關(guān)：光電液位開關(guān)使用紅外線探測，利用光線的折射及反射原理，光線在兩種不同介質(zhì)的分界面將產(chǎn)生反射或折射現(xiàn)象。當被測液體處于高位時則被測液體與光電開關(guān)形成一種分界面，當被測液體處于低位時，則空氣與光電開關(guān)形成另一種分界面，這兩種分界面使光電開關(guān)內(nèi)部光接收晶體所接收的的反射光強度不同，即對應(yīng)兩種不同的開關(guān)狀態(tài)。一般來講，相對其他測量儀表，光電開關(guān)的適用性較差。五，南京電容式液位開關(guān)銷售廠家、音叉液位開關(guān)：通過檢測叉體振動的頻率與振幅的變化輸出一個開關(guān)量信號，通用性較強。對于粘稠性較大的工況需與廠家咨詢確定，易結(jié)晶的工況不建議使用。六、超聲波外測液位開關(guān)：儀表探頭發(fā)射超聲波，南京電容式液位開關(guān)銷售廠家，并檢測其在容器壁中的余振信號，當液體漫過探頭時，此余振信號的幅值會變小，這個改變被儀表檢測到后輸出一個開關(guān)信號。其屬于非接觸式，南京電容式液位開關(guān)銷售廠家，常用于現(xiàn)場不易開孔、高危險場合，但是造價較貴。音叉式液位開關(guān)是一種新型的液位開關(guān)。南京電容式液位開關(guān)銷售廠家</p><div

1.導(dǎo)桿長度：從水箱安裝面到需要檢測的位置，導(dǎo)桿長度超過300MM建議使用不銹鋼材質(zhì)，PP可做25mm-4m,i 不銹鋼可做45mm-4m。 2.材質(zhì)選擇：根據(jù)安裝環(huán)境而定，如：1：水箱不是全密封而且為設(shè)備內(nèi)置則可選擇螺母固定。2：室外水箱或者水池則建議選擇法蘭+接線盒。3：密封性水箱采用大于浮球外徑的外螺紋）。補充：使用環(huán)境（水還是別的液體），螺紋（尺寸）/法蘭（尺寸），是否帶接線盒/是否防暴，溫度：大管做可達300度，小管做可達150度。</p><p style="text-indent:25px">電容式液位開關(guān)是采用偵測液位變化時所引起的微小電容量(通常為PF)差值變化，并由**的ADA電容檢測芯片進行信號處理(可以輸出多種信號通訊協(xié)議，如:IO,BCD, PWM,UART,IIC…)，從而檢測出水位，并輸出信號到輸出端。電容式液位檢測的大優(yōu)勢在于可以隔著任何介質(zhì)檢測到容器內(nèi)的水位或液體的變化，擴展了實際應(yīng)用，同時有效避免了傳統(tǒng)液位檢測方式的穩(wěn)定性、可靠性差的弊端。在某些特殊領(lǐng)域不能檢測的問題，使用內(nèi)置MCU雙核處理的ADA電容檢測芯片的電容式液位開關(guān)，就可以實現(xiàn)很多特殊控制功能，甚至實現(xiàn)更多的集成化、智能化水位檢測功能，諸如太陽能熱水器、咖啡壺等應(yīng)用中掉電后的水位變化也能可靠檢測當前水位，電容式液位檢測是目前液位開關(guān)中有優(yōu)勢的檢測方法。音叉液位開關(guān)基本沒有活動部件，機械磨損比較小，因此無需維護和調(diào)整，使用簡單方便。</p><div

1、適應(yīng)性強：被測介質(zhì)不同的介電參數(shù)、密度對測量均不產(chǎn)生影響。結(jié)垢、攪動、湍流、氣泡、振動、中等粘度、高溫、高壓等惡劣條件對檢測也無影響。 2、不需調(diào)校：由于音叉物位開關(guān)的檢測不受被測介質(zhì)電參數(shù)及密度的影響，所以無論測量何種介質(zhì)都不需要現(xiàn)場調(diào)校。 3、免于維護：由于音叉物位開關(guān)的檢測過程由電子電路完成，無活動部件，所以一經(jīng)安裝投入適用便不需要維護。光電液位開關(guān)使用紅外線探測，利用光線的折射及反射原理。南京電容式液位開關(guān)銷售廠家</p><p style="text-indent:25px">常見的液位開關(guān)種類有哪些?南京電容式液位開關(guān)銷售廠家</p><p style="text-indent:25px">光電液位開關(guān)是一種結(jié)構(gòu)簡單、使用方便、安全可靠的液位開關(guān)，它使用紅外線探測，可避免陽光或燈光的干擾而引起誤動作。其體積小、安裝容易，有雜質(zhì)或帶粘性的液體均可使用，外殼材質(zhì)有聚砜，所以耐油、耐水、耐酸堿。它在凈水/污水處理、造紙、印刷、發(fā)電機設(shè)備、石油化工、食品，飲料、電工、染料工業(yè)、油壓機械等方面都得到了普遍的應(yīng)用。工作原理;光電液位開關(guān)利用光線的折射及反射原理，光線在兩種不同介質(zhì)的分界面將產(chǎn)生反射或折射現(xiàn)象。當被測液體處于高位時則被測液體與光電開關(guān)形成一種分界面，當被測液體處于低位時，則空氣與光電開關(guān)形成另一種分界面，這兩種分界面使光電開關(guān)內(nèi)部光接收晶體所接收的反射光強度不同，即對應(yīng)兩種不同的開關(guān)狀態(tài)。南京電容式液位開關(guān)銷售廠家</p></p><br
