style="text-indent:25px">音叉式液位開關(guān)是一種新型的液位開關(guān)。它是利用音叉振動(dòng)的原理設(shè)計(jì)制作的。它是在音叉液位開關(guān)的感應(yīng)棒底座，透過壓電晶片驅(qū)動(dòng)音叉棒，并且由另外一壓電晶片接受振動(dòng)訊號(hào)，使振動(dòng)訊號(hào)得以循環(huán)，并且使感應(yīng)棒產(chǎn)生共振。當(dāng)物料與感應(yīng)棒接觸時(shí)，振動(dòng)訊號(hào)逐漸變小，直到停止共振時(shí)，控制電路會(huì)輸出電氣接點(diǎn)信號(hào)。由于感應(yīng)棒感度由前端向后座依次減弱的自然原理，所以當(dāng)桶槽內(nèi)物料與桶周圍向上堆積，溫州音叉液位開關(guān)銷售，觸及感應(yīng)棒底座〈后部〉或排料時(shí)，均不會(huì)產(chǎn)生錯(cuò)誤訊號(hào)。簡(jiǎn)單的說，音叉在壓電晶體激勵(lì)下產(chǎn)生機(jī)械振動(dòng)，溫州音叉液位開關(guān)銷售，這種振動(dòng)具有一定的頻率和振幅。當(dāng)音叉被液體或固體浸沒時(shí)，溫州音叉液位開關(guān)銷售，音叉的振動(dòng)頻率和振幅將發(fā)生變化。這個(gè)頻率變化由電子線路檢測(cè)出來并輸出一個(gè)開關(guān)量。電磁式液位開關(guān)：電磁式接近開關(guān)，又稱電感式接近開關(guān)。溫州音叉液位開關(guān)銷售</p><div

style="text-indent:25px">液位傳感器選型和水位開關(guān)的區(qū)別是什么？首先，液位開關(guān)一定顯示液位，而液位傳感器是用電信號(hào)的形式輸出液位的高低。液位開關(guān)是根據(jù)液位傳感器的信號(hào)輸出開啟放水或者進(jìn)水的閥門而使水位保持恒定的一種控制器。液位傳感器的作用是發(fā)出電信號(hào)，如果加上讀取電信號(hào)和顯示的裝置就是電子液位計(jì)了，如果加上讀取電信號(hào)和處理的裝置就是液位控制器。其次，液壓開關(guān)和液位傳感器都是繼電器原理。野鴨開關(guān)是開關(guān)控制電路，而液位傳感器是相當(dāng)于變壓，變流用的電路元件。溫州音叉液位開關(guān)銷售浮球開關(guān)是簡(jiǎn)單的被動(dòng)器件，并且不具有自檢查功能，因此建議對(duì)其進(jìn)行定期檢查與維護(hù)。</p><div

style="text-indent:25px">電纜浮球液位開關(guān)：電纜浮球液位開關(guān)利用重力與浮力的原理設(shè)計(jì)而成，結(jié)構(gòu)簡(jiǎn)單而合理，主要包括浮漂體，設(shè)置在浮漂體內(nèi)的大容量微型開關(guān)和能將開關(guān)處于通斷狀態(tài)的驅(qū)動(dòng)機(jī)構(gòu)，以及與開關(guān)相連的三芯電纜。該液位開關(guān)的特點(diǎn)是性能穩(wěn)定可靠(不因液面的波動(dòng)而引起誤動(dòng)作)，同時(shí)，它還具有無毒、耐腐蝕、安裝方便、使用壽命長(zhǎng)等特點(diǎn)。電式液位開關(guān)：光電液位開關(guān)使用紅外線探測(cè)，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(dāng)被測(cè)液體處于高位時(shí)則被測(cè)液體與光電開關(guān)形成一種分界面，當(dāng)被測(cè)液體處于低位時(shí)，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(qiáng)度不同，即對(duì)應(yīng)兩種不同的開關(guān)狀態(tài)。</p><p style="text-indent:25px">超聲波液位儀特點(diǎn) 1、電路設(shè)計(jì)從電源部分起就選用高質(zhì)量的電源模塊，元器件選擇進(jìn)口高穩(wěn)定可靠的器件，完全可以替代同類型國(guó)外進(jìn)口儀表。 2、的聲波智能技術(shù)軟件可進(jìn)行智能化回波分析，無需任何調(diào)試及其它的特殊步驟，此技術(shù)具有動(dòng)態(tài)思維、動(dòng)態(tài)分析的功能。 3、我公司擁有的聲波智能技術(shù)，使儀表的精度提高，液位精度達(dá)到±0.25%，能夠抗各種干擾波。 4、本儀表是一種非接觸式儀表，不跟液體直接接觸，因此故障率低。儀表提供多種安裝方式，用戶完全可以通過本手冊(cè)進(jìn)行儀表標(biāo)定。 5、儀表的所有輸入、輸出線均具有防雷、防短路的保護(hù)功能。電極式液位器如果用于污水，很快就會(huì)吸附很多雜質(zhì)而無法使用。</p><div style="width:100%;text-align: center;"><img

四、光電液位開關(guān)：光電液位開關(guān)使用紅外線探測(cè)，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(dāng)被測(cè)液體處于高位時(shí)則被測(cè)液體與光電開關(guān)形成一種分界面，當(dāng)被測(cè)液體處于低位時(shí)，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(qiáng)度不同，即對(duì)應(yīng)兩種不同的開關(guān)狀態(tài)。一般來講，相對(duì)其他測(cè)量?jī)x表，光電開關(guān)的適用性較差。五、音叉液位開關(guān)：通過檢測(cè)叉體振動(dòng)的頻率與振幅的變化輸出一個(gè)開關(guān)量信號(hào)，通用性較強(qiáng)。對(duì)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(cè)液位開關(guān)：儀表探頭發(fā)射超聲波，并檢測(cè)其在容器壁中的余振信號(hào)，當(dāng)液體漫過探頭時(shí)，此余振信號(hào)的幅值會(huì)變小，這個(gè)改變被儀表檢測(cè)到后輸出一個(gè)開關(guān)信號(hào)。其屬于非接觸式，常用于現(xiàn)場(chǎng)不易開孔、高危險(xiǎn)場(chǎng)合，但是造價(jià)較貴。溫州音叉液位開關(guān)銷售</p><p
