Photohelic Gauges

Photohelic gauges are commonly used for measuring the differential pressure across applications such as blower pressure, air velocity, differential room pressures, Heating, Ventilation and Air Conditioning (HVAC) Systems.  These run off 24 VDC supply with 2 relay switches.  The simple, friction-less gauge movement quickly indicates low air or non-corrosive gas pressures – either positive, negative (vacuum) or differential.  The design resists shock, vibration and over-pressures.
