Dwyer 2230 MAGNEHELIC, DIFFERENTIAL PRESSURE GAUGE, 0-30 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.

Reliable Differential Pressure Measurement

Engineered for industrial use, the Dwyer 2230 Magnehelic gauge monitors the pressure difference in air and non-corrosive gas systems with precision and reliability. Its acrylic full view lens and robust die-cast aluminum housing ensure resilience and clarity in demanding environments, making it suitable for a range of pressure monitoring applications from HVAC to air filtration systems.


Easy Installation and Versatile Mounting Options

This model supports both surface and flush mounting, allowing for seamless integration into existing equipment panels. The included mounting bracket and two pressure taps, alongside clear instructions, streamline the installation process, doubling down on the devices user-friendly design. The back connection and 1/8 NPT threads further contribute to simple and secure setup.


Durable Design for Long-Term Performance

Crafted from enamel-coated die-cast aluminum and fitted with a silicone rubber seal, the Dwyer 2230 Magnehelic gauge is built to withstand continuous overpressure. Its construction protects against corrosive environments and mechanical wear, while the acrylic lens ensures an unobstructed view of the analog display across the gauges full pressure scale.
