PS10A / PS40A Series pressure switch PS10A series is a pressure type flow detection switch, into PS10-1A (including an SPDT contacts), PS10-2A (including two SPDT contacts), in the wet, dry and pre-action system, Wuhan fm certified fire valves, water valves connected to the alarm interface pipe, fm certification fire valve, the valve is opened based on the flow monitor. Only one sprinkler head movement can flow pressure switch operation. In the pre-action system connected to the valve at the outlet, Wuhan fm certification Fire cocks purchase, pipeline pressure monitoring system, when the pressure decreases, issue a low pressure alarm signal. Operating pressure can be between 4-20psi (0.28-1.38bar) regulation. Switch must be installed vertically. PS40A series of pressure switches for detecting or drop 10psi (0.69bar) ??of pressure change increases the pressure setpoint 10psi (0.69bar). Typical applications are in the pipeline pressure monitoring system in a dry system, or monitoring compressed air tanks, air and water pressure, PS40-1A containing a pair of SPDT contacts, the pressure drop operation; PS40-2A containing two pairs of SPDT contacts, an increase in the pressure setpoint 10psi (0.69bar) ??or drop 10psi (0.69bar) ??occurred. Pressure adjustment range 10-175psi (0.7bar-12bar), the pressure switch must be installed vertically.
