About Dwyer USA Model 2080 Magnehelic Gage Range 0-80 Inch WC

Dwyer USA Model 2080 Magnehelic Gage Range 0-80 Inch WC

 

Using Dwyer's simple, frictionless Magnehelic Gage movement, it quickly indicates low air or non-corrosive gas pressures--either positive, negative (vacuum) or differential. The design resists shock, vibration and over-pressures. No manometer fluid to evaporate, freeze or cause toxic or leveling problems. It's inexpensive, too.

The Magnehelic Gage is the industry standard to measure fan and blower pressures, filter resistance, air velocity, furnace draft, pressure drop across orifice plates, liquid levels with bubbler systems and pressures in fluid amplifier or fluidic systems. It also checks gas-air ratio controls and automatic valves, and monitors blood and respiratory pressures in medical care equipment.

Note: May be used with Hydrogen. Order a Buna-N diaphragm. Pressures must be less than 35 psi.

Features

Bezel provides flange for flush mounting in panel.

Clear plastic face is highly resistant to breakage. Provides undistorted viewing of pointer and scale.

Precision litho-printed scale is accurate and easy to read.

Red tipped pointer of heat treated aluminum tubing is easy to see. It is rigidly mounted on the helix shaft.

Pointer stops of molded rubber prevent pointer over-travel without damage.

"Wishbone" assembly provides mounting for helix, helix bearings and pointer shaft.

Jeweled bearings are shock-resistant mounted; provide virtually friction-free motion for helix. Motion damped with high viscosity silicone fluid.

Zero adjustment screw is conveniently located in the plastic cover, and is accessible without removing the cover. O-ring seal provides pressure tightness.

Helix is precision made from an alloy of high magnetic permeability. Mounted in jeweled bearings, it turns freely, following the magnetic field to move the pointer across the scale.

Samarium Cobalt magnet mounted at one end of range spring rotates helix without mechanical linkages.

Calibrated range spring is flat spring steel. Small amplitude of motion assures consistency and long life. It reacts to pressure on diaphragm. Live length adjustable for calibration.

Silicone rubber diaphragm with integrally molded O-ring is supported by front and rear plates. It is locked and sealed in position with a sealing plate and retaining ring. Diaphragm motion is restricted to prevent damage due to overpressures.

Die cast aluminum case is precision made and iridite-dipped to withstand 168 hour salt spray corrosion test. Exterior finished in baked dark gray hammerloid. One case size is used for all standard pressure options, and for both surface and flush mounting.

Blowout plug of silicone rubber protects against overpressure on 15 psig rated models. Opens at approximately 25 psig.

O-ring seal for cover assures pressure integrity of case.

Durable and Reliable Construction

The Model 2080 Magnehelic Gage features a textured gray die-cast aluminum case with a rugged acrylic cover, ensuring longevity even in demanding industrial environments. Its IP50 rating safeguards internal components from dust, extending operational life and reliability. The phosphor bronze/plastic front lens further protects the clear analog display, ensuring measurements remain visible and accurate over time.


Versatile Applications

This gauge is engineered for use in various applications such as filter monitoring, fan and blower pressure, duct static pressure, air velocity, furnace draft, and assessing pressure drops across orifice plates. Its compatibility with air and non-combustible gases streamlines its role in HVAC, industrial process control, and environmental monitoring, providing efficient pressure tracking for multiple use cases.


Easy Installation and Adjustment

With mounting options including surface or flush installation, the Magnehelic Model 2080 fits seamlessly into different configurations. The included accessories-mounting brackets, screws, NPT plugs, tubing adapters, and comprehensive instructions-facilitate a straightforward setup. Its external zero adjustment screw enables quick recalibration without dismantling, enhancing operational convenience and maintaining measurement precision.
