Dwyer SBLT2/SBLTX系列 投入式液位變送器

SBLT2和(hé)SBLTX系列 投入式液位變送器是具備有多年的制造經驗的産品。它們采用(yòng)液體内的相對(duì)于大(dà)氣壓的靜壓來(lái)測量液位。變送器帶有壓阻式傳感元件密封在316不鏽鋼外(wài)殼内。子彈頭式的設計(jì)，保護傳感元件不受損壞。SBLT2采用(yòng)了(le)雙重避雷科技保護，外(wài)殼接地，可避免閃電雷擊。PBLTX是UL認證的本安型防爆産品可用(yòng)于危險場合。帶有270磅張力的铠裝通氣電纜，可自(zì)動補償大(dà)氣壓的變化。通氣孔帶有過濾芯以防止灰塵或水(shuǐ)滴進入而影響測量值。

特點：

1 優良的防化學腐蝕性能(néng)

2 SBLT2型帶防雷電的功能(néng)

3 通氣過濾頭無需維護保養

4 SBLTX型爲UL本安防爆認證

5 細小(xiǎo)型設計(jì),用(yòng)于空(kōng)間小(xiǎo)的場合
