Perseus Flow Switch (IP, EXia)
FF60 PERSEUS ATEX & IECEx Exd, Exia & INDUSTRIAL FLOW SWITCH
As will be apparent from the illustrations the complete flow switch comprising orifice plate, differential pressure sensitive element and switching mechanism are combined in a single compact assembly which enables easy installation between pipe flanges, models being available for pipe sizes 15 - 250mm diameter. These sensors incorporate a spring loaded pressure sensitive flexible diaphragm, which when deflected by pressure drop across the orifice plate, actuates directly by push rod a snap action S.P.D.T. microswitch at the flow setting. Microswitches can be set for single, dual simultaneuos, or dual independantly adjustable operation. Environmentally sealed or hermetically sealed microswitch options are available.
