Dwyer 2150 Magnehelic Differential Pressure Gauge

The Dwyer 2150 Magnehelic Differential Pressure Gauge is a precision instrument designed for accurate pressure measurement in industrial applications. With a range of 0-150" w.c. and 5.0" w.c. minor divisions, it offers clear readings for filter monitoring, airflow analysis, and building pressure control.

• Precision Measurement & Readability: Range: 0-150" w.c. with 5.0" w.c. minor divisions for detailed pressure analysis. Litho-printed scale with accurate, easy-to-read markings and red-tipped aluminum pointer.
• Rugged Mechanical Design: Magnetic helix mechanism with Samarium Cobalt magnet and precision alloy helix for friction-free motion. Silicone rubber diaphragm with integral O-ring seal and jeweled bearings.
• Durability & Protection: Die-cast aluminum case with Iridite-dipped finish passes 168-hour salt spray test. Includes blowout plug that opens at ~25 psig for overpressure protection.
• User-friendly Design: Zero adjustment screw accessible without disassembly. Wishbone assembly stabilizes components for consistent performance.
• Mounting Versatility: Single case design for surface or flush mounting in control panels or ductwork.
• Environmental Resistance: O-ring seals maintain pressure integrity and protect against dust/water ingress.
