1、適應(yīng)性強(qiáng)：被測(cè)介質(zhì)不同的介電參數(shù)、密度對(duì)測(cè)量均不產(chǎn)生影響。結(jié)垢、攪動(dòng)，上海一球兩點(diǎn)式浮球液位開(kāi)關(guān)廠家電話、湍流、氣泡、振動(dòng)、中等粘度、高溫、高壓等惡劣條件對(duì)檢測(cè)也無(wú)影響。 2、不需調(diào)校：由于音叉物位開(kāi)關(guān)的檢測(cè)不受被測(cè)介質(zhì)電參數(shù)及密度的影響，所以無(wú)論測(cè)量何種介質(zhì)都不需要現(xiàn)場(chǎng)調(diào)校。 3、免于維護(hù)：由于音叉物位開(kāi)關(guān)的檢測(cè)過(guò)程由電子電路完成，上海一球兩點(diǎn)式浮球液位開(kāi)關(guān)廠家電話，無(wú)活動(dòng)部件，所以一經(jīng)安裝投入適用便不需要維護(hù)，上海一球兩點(diǎn)式浮球液位開(kāi)關(guān)廠家電話。電磁式液位開(kāi)關(guān)：電磁式接近開(kāi)關(guān)，又稱電感式接近開(kāi)關(guān)。上海一球兩點(diǎn)式浮球液位開(kāi)關(guān)廠家電話</p><div
