适用于泥水或淤泥中，雷电保护，本安防爆
PBLT2和PBLTX系列 投入式液位变送器是具备有多年的制造经验的产品。它们采用液体内的相对于大气压的静压来测量液位。变送器带有压阻式传感元件密封在316不锈钢外壳内。非常适合用于淤泥和废水等行业，大直径的316不锈钢隔膜密封传感器能保证不会被阻塞。
PBLT2采用了双重避雷科技保护，外壳接地，可避免闪电雷击。PBLTX是UL认证的本安型防爆产品可用于危险场合。
带有270磅张力的铠装通气电缆，可自动补偿大气压的变化。通气孔带有过滤芯以防止灰尘或水滴进入而影响测量值。
特点：
? 316不锈钢和ETFE线缆,良好的化学兼容性能
? PBLT2型带防雷电的功能
? 通气过滤头无需维护保养
? PBLTX型为UL本安防爆认证
? 直径大,不会被堵塞和损坏,316不锈钢膜片密封
