Differential Pressure Indicator

Switzer Instrument offers a differential pressure indicator, Model 120/122/180. Salient features: Switzer differential pressure indicator is a rugged design for industrial use to measure the differential pressure in a filtration system or across a flow orifice or level in a tank and indicates directly on a single gauge dial. A specifically designed magnetic movement allows the instantaneous sensing of both pressures while completely isolating the gauge function from the pressure chamber without the use of mechanical seals. Options: unlike ordinary pressure gauges, these instruments can be supplied with switching facility to initiate an alarm signal or system shutdown. One or two switches can be fixed to open or close on either rising or falling differential pressure. Switch setting is easily made through an external adjustment. This is useful for: pharmaceutical equipment manufacturers, water treatment and chemical plants, hydraulic systems, heat exchangers, filter and bag filter manufacturers, HVAC systems, pumps, valves and compressors and level measurement of cryogenic gases.
