-----產品介紹
代表型號：ECN系列、ECG系列、QZP系列、QZI系列、QZM系列、QZE系列、HK系列。
 
一體型的Eclipsc適用于ISO標準的Namur執行器；*立的可視顯示器（Visual Indicator）在75英尺的范圍內可清楚的觀察閥門位置的狀態；
環氧樹脂涂層鍍鋁的Quartz是防爆/防火環境的*理想選擇；
防腐和防水的SolaR是在過程應用中滿足一般用途的*理想的產品；
*全氣動型的Onxy是防腐蝕性和/或阻燃環境的理想選擇；*全密封的316不銹鋼殼體和熱塑聚碳酸酯檢測探頭的一體式Hawkeye適用于陰燃燃環境。針對石化領域，
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,防爆等級為Eexia llC T6。這樣就*大地提高了總線上可帶閥位指示器的數量。一根總線*多可帶16個閥位指示器，節省了布線。
