代理经销:美国Stonel公司阀位回讯器,限位开关,阀位信号反馈装置
STONEL 阀位回讯器分为6个系列，

一体型的Eclipsc适用于ISO标准的Namur执行器；独立的可视显示器（Visual Indicator）在75英尺的范围内可清楚的观察阀门位置
的状态；环氧树脂涂层镀铝的Quartz是防爆/防火环境的最理想选择；防腐和防水的SolaR是在过程应用中满足一般用途的最理想的产
品；完全气动型的Onxy是防腐蚀性和/或阻燃环境的理想选择；完全密封的316不锈钢壳体和热塑聚碳酸酯检测探头的一体式Hawkeye
适用于阴燃燃环境。
针对石化领域，StoneL推出了FF总线的阀位指示器，这种阀位指示器可选购配套的低功耗防爆电磁阀。电磁阀的电流消耗为2mA@7.5V
,低电压低电流启动,防爆等级为Eexia llC T6。这样就极大地提高了总线上可带阀位指示器的数量。一根总线最多可带16个阀位指示
器，节省了布线

分别为Eclipsc,Visual Indicator,Quartz,SolaR,Onxy,Hawkeye
