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.
