Exd Pressure Switch Model PS-HP
The PS-HP is an adjustable Pressure Switch for use with BERMAD Deluge and control valves, to indicate a pre-determined pressure level. This Pressure Switch offers reliability, repeatability and durability in a compact design. It is suited for operation under the harsh conditions of Zone 1, II 2 G/D Ex d IIC T6 certified for hazardous locations and SIL 2 safety related systems. At the heart of the PS-HP is a snap action Diaphragm assembly, which transfers motion to one SPDT (Single-Pole Double-Throw) micro-switch. Suitable for use with water, air or nitrogen pressure sensing in harsh or hazardous environments as in chemical plants, refineries, gas and petroleum installations offshore and marine vessels.
