Dwyer 2000 MAGNEHELIC DIFFERENTIAL PRESSURE GAUGE 0-200 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 over pressures.

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 Differential Pressure Measurement

The Dwyer 2000-200CM Magnehelic Gauge delivers precise differential pressure readings with a clear, analog display. Its instantaneous response and excellent accuracy make it well-suited for controlling and monitoring air, gas, steam, or liquid pressure in industrial environments. Designed to handle pressures up to 15 psi, this gauge is both reliable and efficient.


Rugged Construction for Demanding Settings

Constructed with a die-cast aluminum case and a durable acrylic cover, the gauge withstands harsh industrial conditions. Its weather-resistant IP54 enclosure protects against dust and splashing water, making it suitable for diverse settings, including steam and oil applications. The 4-inch diameter face ensures visibility and readability from a distance.


Easy Installation and User-Friendly Adjustment

Mounting the Magnehelic is straightforward, thanks to included adapters and a choice of surface or flush mount options. Its clearly labeled 1/8" NPT ports and external zero adjustment screw make setup and calibration quick and hassle-free. Accessories included simplify connection to existing systems, ensuring low maintenance and high performance.
