Dwyer Pressure Gauges

Dwyer Magnehelic differential pressure gauges are designed to indicate air or non-corrosive gas pressures (positive, negative, or differential). These gauges are shock- and vibration-resistant. In addition, they are weatherproof to IP67. 

These gauges are used in a wide range of applications, for example, for the measurement of:

  • fan and blower pressures;
  • filter resistance;
  • air velocity;
  • pressure drop across orifice plates;
  • liquid levels with bubbler systems;
  • pressures in fluid amplifier or fluidic systems.

Dwyer Magnehelic gauges can also be used to check gas-air ratio controls & automatic valves. On top of that, they can monitor blood and respiratory pressures in medical care equipment.
