style="text-indent:25px">液位開關(guān)選型及注意事項：1、液位開關(guān)選型要注意導(dǎo)桿的長度，要從實際安裝面到需要檢測的液位距離。2、螺牙的大小，要根據(jù)安裝環(huán)境而定，比如水箱不是全密封而且為設(shè)備內(nèi)置則可選擇螺母固定，若是室外水箱或者水池則建議選擇法蘭跟接線盒；密封性水箱采用大于浮球外徑的外螺紋鏈接。3、材質(zhì)一般可選不銹鋼304、316、316L/PP/PVDF/噴四氟等，材質(zhì)不同所能夠使用的環(huán)境也不相同。4、線材常規(guī)出線350mm，線材可選高溫編織線、高溫耐腐蝕特氟龍線、護套線、低溫線等等。</p><p style="text-indent:25px">浮球液位開關(guān)的調(diào)試：浮球液位開關(guān)在我們安裝前只需要重新標(biāo)定水位線。無法對開關(guān)本身進行調(diào)整的。這時用萬用表測開關(guān)狀態(tài)，在水線附近會隨水位高低通斷，這說明沒問題。只要保證安裝過程中與熱力設(shè)備的水位線一致就好了。比如SOR的液位開關(guān)吧，一般在筒壁上都貼著水位線，我們把開關(guān)泡在在水槽中，慢慢下沉，使水面逐漸靠近標(biāo)識線，靠近時會聽到微動開關(guān)動作的聲音。需要注意的是：高加液位開關(guān)等的工作溫度高，里邊的水溫也高；高溫水的密度要小于室溫水密度。因而室溫水的動作線比開關(guān)標(biāo)識線要低些的。液位低報警接在常閉上(NC)，液位高接常開(NO)。這類開關(guān)還是不難安裝的。液位開關(guān)本身都會帶兩對以上的微動開關(guān)，分別輸出兩對常開兩對常閉接點，在應(yīng)用時通常是"接通報警"。電子式液位開關(guān)一般采用環(huán)氧樹脂封灌，密封防水。</p><div

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，從而檢測出水位，并輸出信號到輸出端。電容式液位檢測的較大優(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(dāng)前水位，電容式液位檢測是目前液位開關(guān)中較有優(yōu)勢的檢測方法。非接觸式液位開關(guān)的特點在于液位計的顯示結(jié)構(gòu)和介質(zhì)完全隔離。防腐浮球液位控制器廠商</p><p

style="text-indent:25px">非接觸式液位開關(guān)主要有放射性同位素式和超聲波式兩種。對于放射性同位素式液位傳感器,由于它的量程較小,所以不適合大量程液位測量的場合。而超聲波液位傳感器,它不僅量程范圍廣,可用于大量程測量的場合,而且做到了非接觸測量,不受介質(zhì)“結(jié)疤”的影響。非接觸式液位開關(guān)的特點在于液位計的顯示結(jié)構(gòu)和介質(zhì)完全隔離，不會因介質(zhì)的腐蝕、污染等因素而使得觀測受到影響。顯示采用磁性父子和耦合作用作為設(shè)計原理，避免了電力的使用，安裝時不需要考慮電源位置，增加了使用的靈活性。防腐浮球液位控制器廠商</p><p
