Dwyer 2-5000-100MM MINIHELIC II, DIFFERENTIAL PRESSURE GAUGE, 0/100MM

  • Housing is molded from strong mineral and glass filled nylon.
  • Pointer stops of molded rubber prevent pointer over-travel without damage.
  • Full view lens is removable and molded of tough acrylic.
  • Aluminum scale litho-printed black on white, enhances readability.
  • Red tipped aluminum pointer, rigidly mounted to helix is easy to see.
  • Wishbone assembly provides mounting for helix, helix bearings, and pointer shaft.
  • Jewel bearings provide virtually friction-free helix motion.
  • Helix is free to rotate in jewel bearings. It aligns with magnetic field of magnet to transmit pressure indications to pointer.
  • Zero adjustment screw, located behind the removable lens, eliminates tampering.
  • Range spring calibration clamp fixes live length of spring for proper gage calibration and is factory set and sealed.
  • Silicone rubber diaphragm allows accurate response to a broad range of temperatures and at extremely low pressure. Incorporates blow out area for overpressure protection.
  • Diaphragm support plates of lightweight aluminum on each side of the diaphragm minimize position or attitude sensitivity and help define pressure area.
  • Flat leaf range spring reacts to pressure on the diaphragm. Live length is adjustable for calibration. Small amplitude of motion minimizes inaccuracies and assures long life.
  • Low pressure tap connects to rear chamber.
  • Coil spring link provides a resilient connection between the diaphragm and the range spring.
  • Ceramic magnet mounted on a molded bracket at the end of the range spring rotates the helix without direct mechanical linkage.
  • High pressure tap connects with the front chamber through passageway in the plastic case and a sealing ring molded into the edgeof the diaphragm.
