氣體或液體壓力開關；可調范圍：從21～276kPa到1.0～10.3MPa；高/低報警；防雨、防爆
防爆，U.L. & CSA認證，適用于Class I, Groups B, C & D及Class II, Groups E, F & G. H-2型壓力開關是為在液體或氣體上升或下降時，連續進行兩個不同的動作而設計的。專利的設計包含兩個由單膜片、單壓力室操縱的同心活塞。每個活塞驅動一個單獨的開關。這兩個開關可以調整為在量程相反的兩端或量程中間的兩個設定點同時動作。對開關進行現場調整或服務時，只需將帶螺紋的頂端取下，就不會影響電氣或壓力連接。這種Duotect開關可以防爆和抗天氣干擾。它可以安裝在任何位置，且不受振動影響。
