Dwyer 2-5060 Offers

• 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 edgeof the diaphragm.
