SA1112E-S5-K2 美国德威尔隔爆压力开关 dwyer压力开关西安

SA1100系列膜片式压力开关结构坚固，可靠性高，广泛用于化工，石化等工业中。能耐压到3000 psi (206 bar)。回差可低至满量程的5%。典型的应用场合为根据液位来控制水泵的启停。设定点值和回差都是可调的，可透过透明的聚碳酸酯面板观察到，这些都和开关电路部分隔离，更加安全。只需7/16″六角扳手就能调整设置。采用接线端子排接线，内外都带有接地螺丝。标准的外壳防护为提供了内部接线和外部接地，包括内外螺纹连接。标准防护为NEMA4X全天候防护；NEMA 7 防爆防护Class I,Groups B, C & D; NEMA 9,Class II,Groups E, F & G。可选择带泄放阀，防护等级为IP54。
