Dwyer 2220 MAGNEHELIC, DIFFERENTIAL PRESSURE GAUGE, 0-20 PSI

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.

Precision Pressure Monitoring for Critical Environments

The Dwyer 2220 Magnehelic Gauge excels in precise differential pressure measurement tasks, ensuring effective monitoring in HVAC, clean rooms, and filtered environments.

Robust Construction and User-Friendly Design

Crafted from die-cast aluminum with a powder-coated finish and fitted with a clear acrylic lens, the Magnehelic 2220 gauge combines lasting durability with intuitive operation. The external screw-type zero adjustment simplifies recalibration, and the package includes essential mounting hardware. Its 4-inch diameter and clear full-view dial make for easy monitoring at a glance.

FAQs of Dwyer 2220 Magnehelic Differential Pressure Gauge 0-20 PSI:

Q: How is the Dwyer 2220 Magnehelic Differential Pressure Gauge used in HVAC and clean room applications?

A: The 2220 Magnehelic gauge measures differential pressure across filters, airflow in ducts, and room pressure in clean rooms. Its accurate analog readings help maintain targeted environmental parameters essential for optimal operation and compliance within HVAC and controlled room environments.

Q: What materials are used in the construction of the Magnehelic 2220 gauge?

A: This gauge is built with a die-cast aluminum case, silicone rubber diaphragm and seals, a fire-retardant white acrylic dial, a black anodized aluminum pointer, and a clear acrylic lens. Such a selection of materials ensures durability and safe operation in industrial environments.

Q: When should the zero adjustment be performed on the 2220 Magnehelic gauge?

A: Zero adjustment should be carried out during initial installation, after mounting repositioning, or periodically as part of equipment maintenance routines to ensure the accuracy of pressure readings, using the external screw-type adjuster provided.

Q: Where can the Dwyer 2220 Magnehelic Gauge be installed?

A: It is designed for vertical surface or panel mounting using the included bracket and screws. The standard back pressure connection supports easy installation on control panels, walls, or directly near measured systems in industrial facilities.

Q: What is the benefit of the IP55 equivalent enclosure protection for this differential pressure gauge?

A: The IP55 equivalent rating protects the instrument against dust ingress and water jets, enhancing its service life and reliability in dusty or humid industrial settings.

Q: How accurate are the pressure readings on the Magnehelic 2220, and what is its pressure range?

A: The gauge provides readings within 2% of the full 0-20 PSI scale range, making it suitable for precise monitoring of air and non-corrosive gas pressure differences in sensitive environments.

Q: What accessories are included with the Dwyer 2220 Magnehelic Differential Pressure Gauge?

A: The gauge comes with two 1/8 NPT plugs, two mounting screws, and a surface mounting bracket. These accessories facilitate quick and secure installation for a variety of monitoring applications.
