哈爾濱液位計(jì)多少錢磁致伸縮液位計(jì)的優(yōu)點(diǎn)？</p><div style="width:100%;text-align: center;"><img style="max-width: 640px; max-height: 320px;" alt="長(zhǎng)沙專業(yè)液位計(jì)選型,液位計(jì)" src="https://tyunfile.71360.com/UploadFile/kytdck/637231460593037109/1502139.jpg"></div><p> <span style="font-size:16px;">磁致伸縮液位計(jì)的工作原理是什么？</span> </p> <p> <span style="font-size:16px;"> 磁致伸縮液位計(jì)由三部分組成：探測(cè)桿，電路單元和浮子組成。該液位計(jì)測(cè)量時(shí)，電路單元產(chǎn)生電流脈沖，該脈沖沿著磁致伸縮線向下傳輸，并回產(chǎn)生一個(gè)環(huán)形的磁場(chǎng)。在探測(cè)桿外配有浮子，浮子沿探測(cè)桿隨液位的變化而上下移動(dòng)。由于浮子內(nèi)裝有一組永磁鐵，所以浮子同時(shí)產(chǎn)生一個(gè)磁場(chǎng)。當(dāng)電流磁場(chǎng)與浮子磁場(chǎng)相遇時(shí)，產(chǎn)生一個(gè)“扭曲”脈沖，或稱“返回”脈沖。將“返回”脈沖與電流脈沖的時(shí)間差轉(zhuǎn)換成脈沖信號(hào)，從而計(jì)算出浮子的實(shí)際位置，測(cè)答得液位。</span> </p><h1> <span style="font-size:16px;">玻璃管液位計(jì)</span><span style="font-size:16px;">維護(hù)保養(yǎng)也很重要，主要包括以下的三點(diǎn)：</span> </h1> <p> <p> <span style="font-size:16px;"> <p> 1、使用中的液位計(jì)定期檢查。清洗玻璃內(nèi)外壁污垢，使液體顯示清晰。 </p> <p> 2、為了保證片動(dòng)密超過計(jì)劃作用，容器內(nèi)的介質(zhì)壓力應(yīng)大于0.2MPa,在打開上下閥時(shí)，閥桿退出轉(zhuǎn)數(shù)不小于4轉(zhuǎn)(使鋼球封門時(shí)，不致于碰到閥桿的頂端。) </p> <p> 3、容器上與本玻璃管液位計(jì)連接的兩法蘭端面應(yīng)保證在同一垂直平面內(nèi)，否則在液位計(jì)安裝后使閥門撓曲，以致玻璃管折斷。 </p> <p> 通過以上信息的說(shuō)明，就算是行外漢也會(huì)對(duì)玻璃管液位計(jì)多少有點(diǎn)了解的，重要的是不**會(huì)使用，也要定時(shí)的養(yǎng)護(hù)！ </p> </span>

style="font-size:16px;">1、測(cè)量物質(zhì)：</span> </p> <p> <span style="font-size:16px;">超聲波液版位計(jì)用于各種液體和固體物料高度的測(cè)量。水及污水處理：泵房、集水井、生化反應(yīng)池、沉淀池等；電力、礦山：灰漿池、煤漿池、水處理等。</span> </p> <p> <span

style="font-size:16px;">液位計(jì)注意事項(xiàng)</span> </h1> <p> <span style="font-size:16px;"> 1、切勿用高于36V電壓加到變送器上，否則會(huì)導(dǎo)致變送器損壞；</span> </p> <p> <span style="font-size:16px;"> 2、切勿用硬物碰觸膜片，否則會(huì)導(dǎo)致隔離膜片損壞；</span> </p> <p> <span style="font-size:16px;"> 3、液位傳感器測(cè)量的介質(zhì)不允許結(jié)冰，否則將損傷傳感器元件隔離膜片，導(dǎo)致變送器損壞，必要時(shí)需對(duì)變送器進(jìn)行溫度保護(hù)，以防結(jié)冰；</span> </p> <p> <span style="font-size:16px;"> 4、在測(cè)量蒸汽或其他高溫介質(zhì)時(shí)，其溫度不應(yīng)超過液位傳感器使用時(shí)的極限溫度，高于變液位傳感器使用的極限溫度必須使用散熱裝置；</span> </p> <p> <span style="font-size:16px;"> 5、測(cè)量蒸汽或其他高溫介質(zhì)時(shí)，應(yīng)使用散熱管，使液位傳感器和管道連在一起，并使用管道上的壓力傳至變壓器。當(dāng)被測(cè)介質(zhì)為水蒸氣時(shí)，散熱管中要注入適量的水，以防過熱蒸汽直接與液位傳感器接觸，損壞傳感器；</span> </p> <p> <span style="font-size:16px;"> 6、在壓力傳輸過程中，應(yīng)注意以下幾點(diǎn)，</span> </p> <p> <span style="font-size:16px;"> a、液位傳感器與散熱管連接處，切勿漏氣；</span> </p> <p> <span style="font-size:16px;"> b、開始使用前，如果閥門是關(guān)閉的，則使用時(shí)，應(yīng)該非常小心、緩慢地打開閥門，以免被測(cè)介質(zhì)直接沖擊液位傳感器膜片，從而損壞傳感器膜片；</span> </p> <p> <span style="font-size:16px;"> c、管路中必須保持暢通，管道中的沉積物會(huì)彈出，并損壞傳感器膜片。</span>
