Dwyer 2003 Magnehelic Differential Pressure Gauge 0-3 In WC w/ Panel

Dwyer 2003 Magnehelic Differential Pressure Gauge 0-3 In WC w/ Panel

The Dwyer 2003 is a Series 2000 Magnehelic differential pressure gauge with a 0-3 inch water column range. It uses Dwyer's frictionless Magnehelic movement to measure air or noncorrosive gas pressure — positive, negative (vacuum), or differential — with no mechanical friction that could cause hysteresis or sticking. This unit is mounted in a stainless steel panel housing and has been tested at our facility and confirmed to be in good working order.

Applications

The Dwyer Series 2000 Magnehelic gauge is one of the most widely used low differential pressure gauges in HVAC, building automation, and industrial process control. It is commonly used to monitor air filter loading across filter banks, measure duct static pressure, check fan and blower performance, and verify pressure drop across heat exchangers and coils. The frictionless Magnehelic movement makes it well suited for continuous monitoring applications where accuracy and repeatability matter. The IP67 weatherproof rating allows installation in outdoor or wet environments, and the design's resistance to shock and vibration makes it reliable in mechanical rooms and air-handling unit (AHU) enclosures. Dwyer Magnehelic gauges have been an industry standard in commercial HVAC and cleanroom pressure monitoring since the 1950s and remain in widespread current use across these fields.
