Dwyer USA 2005 Magnehelic Gage Range 0-5.0 Inch WC

Description

Dwyer 2005 Differential pressure gage, range 0-5.0" w.c. (inches of water), minor divisions .10.

Using Dwyers 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. Its 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.

Engineered for Precise Low-Pressure Measurement

The Dwyer 2005 Magnehelic Gage ensures high repeatability and accuracy for industrial applications such as duct static pressure, filter monitoring, and clean room pressure control. Built with a reliable diaphragm sensor and providing virtually immediate mechanical response, it is suited for demanding environments where real-time readings are crucial.


Designed for Versatility and Durability

Housed in powder-coated, anodized die-cast aluminum, the Magnehelic gauge features both side and back connections for flexible installation. Its IP52 enclosure and wide operating temperature range allow usage in various climates, while its polycarbonate window guarantees clarity and protection in challenging conditions.


Effortless Installation and User-Friendly Operation

The gauge comes with all necessary accessories for panel or surface mounting, including adapters, screws, and clear instructions. Simple zero adjustment on the front allows quick recalibration, ensuring ongoing precision without hassle. Clear analog display promotes easy reading for users at all levels.
