Series 2000 Magnehelic® gage for high accuracy--guaranteed within 2% of full scale--and for the wide choice of 81 models available to suit your needs precisely. Using Dwyer's simple, frictionless Magnehelic® gage movement, it quickly indicates low air or non-corrosive gas pressures--either positive, negative (vacuum) or differential. The design resists shock, vibration and over-pressures.

  • 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 hr 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
  • 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
  • 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
  • Relief plug opens at approximately 25 psig (1.72 bar), standard gages only
