The Series 2000 magnehelic gauge for a versatile low differential pressure gauge with a wide choice of 81 model and 27 options to choose from. Using Dwyer's simple, frictionless magnehelic gauge movement, it quickly indicates air or non-corrosive gas pressures either positive, negative (vacuum) or differential. The design resists shock, vibration, over pressures and is weather-proof to IP67. Select the HA high-accuracy magnehelic gauge option for an accuracy within 1% of full scale, located below in the product configurator.
Dwyer® Magnehelic Differential Pressure Gauge, Series: 2000 Series, 4 in Dial, 0 to 3 in-WC Measuring, +/-2 % Accuracy, 1/8 in Connection, FNPT Connection, IP67 Enclosure, Die-Cast Aluminum, 20 to 140 deg F
- Easy to read gauge through undistorted plastic face permits viewing from far away
- Patented design provides quick response to pressure changes means no delay in assessing critical situations
- Durable and rugged housing and high-quality components combine to provide long service life and minimized down time
- High-accuracy option is twice as accurate as the standard magnehelic gage
- Bezel provides flange for flush-mounting in panel
- Clear plastic face is highly resistant to breakage, provides undistorted viewing of pointer and scale
- 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
- Jewelled 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
- 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 hr salt spray corrosion test, exterior finished in baked dark gray hammerloid, 1-case size is used for all standard pressure options and for both surface and flush-mounting
- O-ring seal for cover assures pressure integrity of case
- Samarium cobalt magnet-mounted at one end of range spring rotates helix without mechanical linkages
- Exterior finish is coated gray to withstand 168 hr salt spray corrosion test
