style="text-indent:25px">射頻導(dǎo)納物位開關(guān)選型注意事項：一、被測物料的性質(zhì) 首先，其測量電學(xué)對象是物料的電抗特性，物料就需要有一定的介電常數(shù)，射頻導(dǎo)納物位開關(guān)*能用于介電常數(shù)≥1.6的物位測量。其次，射頻導(dǎo)納物位開關(guān)為接觸性測量，其探頭直接接觸被測物料，故被測物料不能過大，否則射頻導(dǎo)納探頭容易被砸彎損壞。二、被測物料的溫度及壓力因為射頻導(dǎo)納探頭直接接觸被測物料，受探頭材料限制，當(dāng)溫度大于260℃時，需選用超高溫型射頻導(dǎo)納物位開關(guān)，計為自動化設(shè)計的超高溫型射頻導(dǎo)納物位開關(guān)，耐溫高達(dá)400℃，能滿足大部分工業(yè)環(huán)境的需求。其次受限于探頭的制造工藝，探頭耐壓一般在2MPa以**頻導(dǎo)納物位開關(guān)基本都應(yīng)用于常壓或者微壓環(huán)境。電容物位開關(guān)是一種新型的物位儀表。</p><div
