Dwyer Magnehelic differential pressure gauge 2000 series 2000-10MM MM of water

Dwyer Magnehelic differential pressure gauge 2000 series 2000-10MM MM of water

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.
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.
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.
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.
O-ring seal for cover assures pressure integrity of case.
