SBLT2和SBLTX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)。頭式的設(shè)計(jì)，保護(hù)傳感元件不受損壞。
SBLT2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)：
? 優(yōu)良的防化學(xué)腐蝕性能
? SBLT2型帶防雷電的功能
? 通氣過(guò)濾頭無(wú)需維護(hù)保養(yǎng)
? SBLTX型為UL本安防爆認(rèn)證
? 細(xì)小型設(shè)計(jì),用于空間小的場(chǎng)合
