PBLT2和PBLTX潛水式液位變送器可在的應(yīng)用環(huán)境中多年*運(yùn)行。這兩種方法都是根據(jù)大氣壓測(cè)量罐內(nèi)液體的高度。變送器由壓阻式傳感元件組成，封裝在316不銹鋼外殼中。非常適合廢水和泥漿應(yīng)用，具有保護(hù)裝置免受這些苛刻應(yīng)用的特點(diǎn)。大直徑316不銹鋼隔膜密封無(wú)堵塞，抗漂浮固體損壞。
PBLT2采用雙避雷器技術(shù)，結(jié)合雷電和浪涌保護(hù)，接地至外殼，消除電源浪涌和雷電接地瞬變（浪涌保護(hù)不受保證，不在保修范圍內(nèi)）。PBLTX是UL認(rèn)證的本質(zhì)安全型，與適當(dāng)?shù)钠琳弦黄鹗褂脮r(shí)，可在危險(xiǎn)場(chǎng)所使用。電纜中的通風(fēng)管自動(dòng)補(bǔ)償罐上方大氣壓力的變化。排氣口由免維護(hù)過(guò)濾器保護(hù)，防止微?；蛩芜M(jìn)入傳感器
