Dwyer 2-5000-125PA MINIHELIC II, DIFFERENTIAL PRESSURE GAUGE, 0/125 PA
- 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.
