The Magnehelic pressure gage is a versatile, low differential pressure gage that 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.
Features:
- Easy to read gage 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 longservice 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.
- 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.
- 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.
