Owing to the efforts of our skilled professionals, we have been constantly engaged in offering a qualitative assortment of Magnehelic Gauge.

Fetaures:

• Magnehelic Differential Pressure Gage Indicate Positive, Negative or Differential, Accurate within 2%
• Select the 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 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
• Used with Hydrogen. Order a Buna-N diaphragm. Pressures must be less than 35 psi.
• 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:

• Blowout plug is comprised of a rubber plug on the rear which functions as a relief valve by unseating and venting the gage 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 gage is surface mounted

Other Features:

• 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 gages 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 gage to fail due to over pressurization
• 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 resulting in property damage or serious injury, Good engineering practices should be utilized to prevent your system from exceeding
• 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
• Die cast aluminum case is precision made and iridite-dipped to withstand 168 hour salt spray corrosion test Exterior finished in baked dark gray hammertoe, One case size is used for all standard pressure options, and for both surface and flush mounting
