Easy to read gauge through undistorted plastic face permits viewing from far away
Durable and rugged housing and high quality components combine to provide long service life and minimized down time
High accuracy option is twice as accurate as the standard Magnehelic gauge
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
Patented design provides quick response to pressure changes means no delay in assessing critical situations
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
Over-pressure 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)
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
