Differential pressure gage | range 0-20 kPa | minor divisions .50.
Series 2000 Magnehelic® Differential Pressure Gages
- No Power Required
- Low Cost
- Used in Isolation/ Hospital Environments and Temporary Units (no power required)
Select the Series 2000 Magnehelic® Gage for a versatile low differential pressure gage with a wide choice of 81 models and 27 options to choose from. Using Dwyer’s simple, frictionless Magnehelic® gage movement, it quickly indicates air or noncorrosive gas pressures–either positive, negative (vacuum) or differential. The design resists shock, vibration, over-pressures and is weatherproof to IP67. Select the -HA High Accuracy Magnehelic® Gage option for an accuracy within 1% of full scale, located below in the Product Configurator. Also included with the –HA option at no extra cost are a mirrored scale overlay and a 6 point calibration certificate.
NIST CALIBRATION available in Product Configurator.
Note: May be used with Hydrogen. Order a Buna-N diaphragm. Pressures must be less than 35 psi.
Please see Series AT-2000 for ATEX approved.

Product Applications
- Filter Monitoring
- Air Velocity with Dwyer Pitot Tube
- Blower Vacuum Monitoring
- Fan Pressure Indication
- Duct, Room or Building Pressures
- Clean Room Positive Pressure Indication
- Easy to read gage through undistorted plastic face permits viewing from far away
- Patented design provides quick response to pressure changes means no delay inassessing critical situations
- Durable and rugged housing and high-quality components combine to provide longservicelife 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.
- 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.
- 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.

OVERPRESSURE PROTECTION
Blowout plug is comprised of a rubber plug on the rear whichfunctions as a relief valve by unseating and venting the gageinterior when over pressure reaches approximately 25 psig (1.7bar). To provide a free path for pressure relief, there are fourspacer pads which maintain 0.023″ clearance when gage issurface mounted. Do not obstruct the gap created by these pads.The blowout plug is not used on models above 180″ of waterpressure, medium or high pressure models, or on gages whichrequire an elastomer other than silicone for the diaphragm.The blowout plug should not be used as a system overpressurecontrol. High supply pressures may still cause the gage to fail dueto over pressurization, resulting in property damage or seriousinjury. Good engineering practices should be utilized to preventyour system from exceeding the ratings of any component. - O-ring seal for cover assures pressure integrity of case.
- Samarium Cobalt magnet mounted at one end of range springrotates helix without mechanical linkages.
