Overview
The Dwyer 2030C differential pressure gauge is a Series 2000 Magnehelic instrument designed for precise measurement of low-level air and non-corrosive gas pressures in positive, negative (vacuum), or differential modes. The simple, frictionless Magnehelic gauge movement quickly indicates air or noncorrosive gas pressures either positive, negative (vacuum) or differential. The design resists shock, vibration, over-pressures and is weatherproof to IP67. This gauge requires no electrical power and eliminates the maintenance issues associated with liquid manometers.
Key Features
- Frictionless Magnetic Movement: No manometer fluid to evaporate, freeze or cause toxic or leveling problems.
- Robust Construction: Body Material: Die Cast Aluminum with shock and vibration resistance
- Wide Application Range: Typical applications include filter monitoring, air velocity with Dwyer Pitot tube, blower vacuum monitoring, fan pressure indication, Duct, room or building pressures, clean room positive pressure indication.
- Easy Installation: Two 1/8″ NPT plugs for duplicate pressure taps, Two 1/8″ pipe thread to rubber tubing adapters, Three flush mounting adapters with screws.
- High Accuracy: ±2% full scale accuracy for reliable pressure measurement
