Dwyer 2000 MAGNEHELIC, DIFFERENTIAL PRESSURE GAUGE 0-150 CM

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 Air and Gas Applications

The Dwyer 2000-150CM is engineered for exceptionally accurate differential pressure readings, with a scale range of 0-150 mm H2O and 2% full-scale accuracy. Its industrial-grade diaphragm sensor ensures reliable performance in monitoring air and non-combustible gas pressures across a variety of systems, from HVAC to cleanrooms.


Rugged Design for Demanding Environments

Protected by a die-cast aluminum housing and a clear acrylic face, this gauge is suited for tough conditions. It withstands operating temperatures from -7C to 60C and offers an IP52 rating, safeguarding against dust and light splashes. The grey, powder-coated finish and anodized components enhance its corrosion resistance.


Flexible Installation and User-Friendly Features

Mount the Magnehelic gauge easily on panels or surfaces using included adaptors. Its dual side and rear 1/8 NPT ports allow variable connection options. External zero adjustment and clear analogue dial with matte aluminum finish make readings straightforward and routine maintenance hassle-free.
