2002AV
The Dwyer 2002AV Magnehelic Differential Pressure Gauge has an accuracy within 2%. The simple, frictionless Magnehelic gauge movement indicates low air or non-corrosive gas pressures; either positive, negative (vacuum) or differential. It resists shock, vibration and over-pressures.
- Dual Range: 0-2.0" w.c./1000-5600 FPM
- Red tipped pointer of heat treated aluminum tubing is easy to see
- O-ring seal provides pressure tightness
- Zero adjustment screw
- Range in w.c./Velocity F.P.M.: 0-2.0" / 1000-5600
- Bezel provides flange for flush mounting in panel
- Clear plastic face is highly resistant to breakage
- Precision litho-printed scale is accurate and easy to read
- Red tipped pointer of heat treated aluminum tubing is easy to see and 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
- O-ring seal provides pressure tightness
- Helix is precision made from an alloy of high magnetic permeability
- Calibrated range spring is flat spring steel
- Silicone rubber diaphragm with integrally molded O-ring is supported by front and rear plates
- Diaphragm locked and sealed in position with a sealing plate and retaining ring
- Overpressure Protection
- Blowout plug
- Die cast aluminum case is precision made and iridite-dipped
- 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
- 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.
- Zero adjustment screw is conveniently located in the plastic cover, and is accessible, without removing cover. O-ring seal provides pressure tightness.
- 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.
- Overpressure Protection
- Blowout plug is comprised of a rubber plug on the rear which functions as a relief valve by unseating and venting the gauge interior when over pressure reaches approximately 25 psig (1.7 bar). To provide a free path for pressure relief, there are four spacer pads which maintain 0.023" clearance when gauge is surface mounted. Do not obstruct the gap created by these pads. The blowout plug is not used on models above 180" of water pressure, medium or high pressure models, or on gauges which require an elastomer other than silicone for the diaphragm. The blowout plug should not be used as a system overpressure control. High supply pressures may still cause the gauge to fail due to over pressurization, resulting in property damage or serious injury. Good engineering practices should be utilized to prevent your system from exceeding the ratings of any component.
- 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.
- 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
The Dwyer 2002AV Magnehelic Differential Pressure Gauge, Dual Scale, 0-2.0" w.c., 1000-5600 FPM for high accuracy and with a dual W.C. and Air Velocity scale that has an accuracy within 2%.
