Dwyer 2205 MAGNEHELIC, DIFFERENTIAL PRESSURE GAUGE, 0-5 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.

Robust Industrial Design

Built for industrial environments, the Dwyer 2205 Magnehelic features a die-cast aluminum case, a matte black finish, and an IP53 enclosure rating. It's designed to withstand challenging conditions, including temperatures from -20C to 60C, making it dependable in a wide range of applications.


Precise and Immediate Pressure Readings

This gauge employs a mechanical diaphragm sensor to provide fast and accurate analog readings with 2% full-scale accuracy. With an external zero adjustment screw and clear, easy-to-read dial, users can quickly ensure precision measurements for critical pressure monitoring tasks.


Flexible Installation and Easy Maintenance

Supplied with essential accessories such as plugs, adapters, and flush mounting hardware, the Dwyer 2205 Magnehelic is suitable for both surface and panel mounting. The light 400g design and external zeroing simplify installation and ongoing maintenance, enhancing operational convenience.
