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.

Precision Measurement for Industrial Applications

The Dwyer 2205 Magnehelic Differential Pressure Gauge offers reliable and accurate pressure readings in environments where monitoring air or non-corrosive gases is crucial. Its resolution of 0.1 PSI, 2% full-scale accuracy, and immediate mechanical response ensure that critical measurements are accessible at a glance for safety and process control.


Durable and Versatile Construction

Built with a die-cast aluminum case and clear acrylic cover, this gauge stands up to demanding conditions. The IP52 enclosure protects against dust and dripping water, while the corrosion-resistant finish extends usable life. The 2205 model comes with mounting accessories for both surface and flush installation, making it adaptable for various setups.


Easy Installation and Adjustment

With female 1/8" NPT high and low pressure ports and included adapters, integration into existing systems is straightforward. The external zero adjustment screw allows users to recalibrate the gauge without disassembly, ensuring ongoing measurement accuracy with minimal downtime.
