Dwyer 2150 Magnehelic Differential Pressure Gauge

Product Introduction

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. The gauge features a magnetically coupled helix mechanism and silicone rubber diaphragm for reliable performance, while its die-cast aluminum case ensures durability in harsh environments. Ideal for both surface and flush mounting, it combines ease of use with robust construction for long-term reliability.

Product Features

Precision Measurement & Readability:

Range: 0–150" w.c. with 5.0" w.c. minor divisions for detailed pressure analysis.

Litho-printed Scale: Accurate and easy-to-read markings for quick visual interpretation.

Red-tipped Aluminum Pointer: Rigidly mounted on the helix shaft for high visibility.

Rugged Mechanical Design:

Magnetic Helix Mechanism: Samarium Cobalt magnet and precision alloy helix for friction-free motion.

Silicone Rubber Diaphragm: Integral O-ring seal with front/rear plate support, resists overpressure damage.

Jeweled Bearings: Shock-resistant mounting ensures smooth, low-friction helix operation.

Durability & Protection:

Die-cast Aluminum Case: Iridite-dipped to pass 168-hour salt spray test, finished in baked gray hammerloid.

Blowout Plug: Silicone rubber plug opens at ~25 psig to protect against overpressure (15 psig rated models).

Viscous Silicone Damping: Minimizes pointer oscillation in dynamic pressure environments.

User-friendly Design:

Zero Adjustment Screw: Accessible through plastic cover without disassembly.

Wishbone Assembly: Stabilizes helix, bearings, and pointer shaft 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.
