Dwyer Magnehelica mechanical differential pressure gauge delivers high-precision measurement within ±2% of full scale, featuring 81 selectable ranges to precisely meet diverse application needs. Utilizing simple, non-wearing Magnehelica moving components, this gauge rapidly indicates low pressures of air or non-corrosive gases—including positive pressure, negative pressure (vacuum), or differential pressure.
Engineered to resist shock, vibration, and overpressure, it eliminates issues like manometer liquid evaporation, freezing, or poisoning, while offering a cost-effective solution. Widely applied in measuring fan pressure, blower resistance, filter pressure drop, wind speed, furnace draft, orifice plate pressure loss, foaming system liquid level, fluid amplifier pressure, and hydraulic system pressure. It also detects gas-to-air ratio controls, automatic valves, and monitors blood/respiratory pressure in medical care equipment.
