氣體或液體壓力開關(guān)；可調(diào)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(guān)是為在液體或氣體上升或下降時，連續(xù)進行兩個不同的動作而設(shè)計的。專利的設(shè)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(qū)動一個單獨的開關(guān)。這兩個開關(guān)可以調(diào)整為在量程相反的兩端或量程中間的兩個設(shè)定點同時動作。對開關(guān)進行現(xiàn)場調(diào)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(guān)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。
