適用于泥水或淤泥中，雷電保護，本安防爆

PBLT2和PBLTX系列 投入式液位變送器是具備有多年的制造經(jīng)驗的產(chǎn)品。它們采用液體內(nèi)的相對于大氣壓的靜壓來測量液位。變送器帶有壓阻式傳感元件密封在316不銹鋼外殼內(nèi)。非常適合用于淤泥和廢水等行業(yè)，大直徑的316不銹鋼隔膜密封傳感器能保證不會被阻塞。

PBLT2采用了雙重避雷科技保護，外殼接地，可避免閃電雷擊。PBLTX是UL認證的本安型防爆產(chǎn)品可用于危險場合。

帶有270磅張力的鎧裝通氣電纜，可自動補償大氣壓的變化。通氣孔帶有過濾芯以防止灰塵或水滴進入而影響測量值。
特點：

? 316不銹鋼和ETFE線纜,良好的化學兼容性能

? PBLT2型帶防雷電的功能

? 通氣過濾頭無需維護保養(yǎng)

? PBLTX型為UL本安防爆認證

? 直徑大,不會被堵塞和損壞,316不銹鋼膜片密封
