Dwyer 2-5001 Minihelic Differential Pressure Gauge 0-1.0 INCH WC
Dwyer 2-5001 Offers
Features
- Housing is moulded from strong mineral and glass filled nylon
- Pointer stops of moulded rubber prevent pointer over-travel without damage
- Full view lens is removable and moulded 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 moulded 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 moulded into the edge of the diaphragm
Applications
- Room Positive Pressure Sensing
- Local Indication on Filter Status
- Face Velocity on Fume Hood
- Duct Pressures
