| Magnehelic And Photohelic Differential Pressure Gauge
- The Series A3000 PHOTOHELIC Switch/Gage is a versatile 2-in-1 instrument combining a time-proven Magnehelic differential pressure gage with low/high pressure switches. It is designed to measure and control positive, negative or differential pressure of air or other non-combustible, non-corrosive gases. Gage reading is unaffected by switch operation. Switch set points are easily adjusted with knobs located on gage face. Applied pressure and switch set points are fully visible at all times. Deadband is one pointer width, less than 1% of full scale. Each set point controls a DPDT relay and both relays can be interlocked to provide variable deadband control.
- The Magnehelic is the industr y standard to measure fan and blower pressures,filter resistance, air velocity, furnace draft, pressure drop across orificeplates, liquid levels with bubbler systems and pressures in fluid amplifier or fluidic systems. It also checks gas-air ratio controls and automatic valves, and monitors blood and respiratory pressures in medical care equipment. Magnehelic gages have east-to-read 4" dials that quickly indicate low air or gas pressures-positive, negative air differential.
