      分享

      SBLT2和SBLTX系列 投入式液位變送器是具備有多年的制造經驗的產品。它們采用液體內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。子彈頭式的設計,保護傳感元件不受損壞。SBLT2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:

      1 優良的防化學腐蝕性能

      2 SBLT2型帶防雷電的功能

      3 通氣過濾頭無需維護保養

      4 SBLTX型為UL本安防爆認證

      5 細小型設計,用于空間小的場合
