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(yàn)的產(chǎn)品。它們采用液體內(nèi)的相對(duì)于大氣壓的靜壓來(lái)測(cè)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(huì)被阻塞。
PBLT2采用了雙重避雷科技保護(hù)，外殼接地，可避免閃電雷擊。PBLTX是UL認(rèn)證的本安型防爆產(chǎn)品可用于危險(xiǎn)場(chǎng)合。
帶有270磅張力的鎧裝通氣電纜，可自動(dòng)補(bǔ)償大氣壓的變化。通氣孔帶有過(guò)濾芯以防止灰塵或水滴進(jìn)入而影響測(cè)量值。
特點(diǎn)：
• 316不銹鋼和ETFE線纜,良好的化學(xué)兼容性能
• PBLT2型帶防雷電的功能
• 通氣過(guò)濾頭無(wú)需維護(hù)保養(yǎng)
• PBLTX型為UL本安防爆認(rèn)證
• 直徑大,不會(huì)被堵塞和損壞,316不銹鋼膜片密封
