代理經(jīng)銷:美國Stonel公司閥位回訊器,限位開關(guān),閥位信號(hào)反饋裝置
STONEL 閥位回訊器分為6個(gè)系列,
一體型的Eclipsc適用于ISO標(biāo)準(zhǔn)的Namur執(zhí)行器;獨(dú)立的可視顯示器(Visual Indicator)在75英尺的范圍內(nèi)可清楚
的觀察閥門位置
的狀態(tài);環(huán)氧樹脂涂層鍍鋁的Quartz是防爆/防火環(huán)境的理想選擇;防腐和防水的SolaR是在過程應(yīng)用中滿足一
般用途的理想的產(chǎn)
品;完全氣動(dòng)型的Onxy是防腐蝕性和/或阻燃環(huán)境的理想選擇;完全密封的316不銹鋼殼體和熱塑聚碳酸酯檢測(cè)探
頭的一體式Hawkeye
適用于陰燃燃環(huán)境。
針對(duì)石化領(lǐng)域,StoneL推出了FF總線的閥位指示器,這種閥位指示器可選購配套的低功耗防爆電磁閥。電磁閥的
電流消耗為2mA@7.5V
,低電壓低電流啟動(dòng),防爆等級(jí)為Eexia llC T6。這樣就極大地提高了總線上可帶閥位指示器的數(shù)量。一根總線多
可帶16個(gè)閥位指示
器,節(jié)省了布線
分別為Eclipsc,Visual Indicator,Quartz,SolaR,Onxy,Hawkeye
