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。液位開關(guān)，也稱水位開關(guān)，液位傳感器。</p><div style="width:100%;text-align: center;"><img style="max-width: 640px; max-height: 320px;"
