Housing Is Molded From Strong Mineral And Glass Filled Nylon. Pointer Stops of Molded Rubber Prevent Pointer Over Travel Without Damage.

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 gauge 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 edge of the diaphragm.
