Description

  • Indicates positive, negative, or differential pressure
  • Bezel provides flange for flush mounting in panel
  • Clear plastic face is highly resistant to breakage and 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
  • 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 to provide virtually friction-free motion for helix, and are motion damped with high viscosity silicone fluid
  • Zero adjustment screw is conveniently located in the plastic cover, and is accessible without removing the cover, while O-ring seal provides pressure tightness
  • Helix, mounted in jeweled bearings, is precision made from an alloy of high magnetic permeability and turns freely, following the magnetic field to move the pointer across the scale
  • Calibrated range spring is flat spring steel and small amplitude of motion assures consistency and long life
  • Silicone rubber diaphragm with integrally molded O-ring is supported by front and rear plates and 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, and the exterior is finished in baked dark gray hammerloid
  • Samarium cobalt magnet mounted at one end of range spring rotates helix without mechanical linkages
