MORE ABOUT THIS ITEM
The Magnahelic guage is the industry standard to measure fan and blower pressures, filter resistance, air velocity, furnace draft, pressure drop across orifice plates, liquid levels with bubbler systems, and pressures in fluid amplifier or fluidic systems. The gauge's motion is damped with high-viscosity silicone fluid. The zero adjustment screw is conveniently located in the plastic cover, and is accessible without removing the cover. O-ring seal provides pressure tightness. Rugged design resists shock, vibration, and overpressure.
The helix is precision-made from an alloy of high magnetic permeability. Mounted in jeweled bearings, it turns freely, following the maganetic field to move the pointer across the scale. The samarium cobalt magnet is mounted at one end of the range spring and rotates the helix without mechanical linkages.

High Accuracy Differential Pressure MeasurementThe Magnehelic Gauge measures very low pressure differences with exceptional 2% full scale accuracy, suitable for tasks requiring sensitive monitoring. Its mechanical, diaphragm-based sensor eliminates the need for external power, ensuring reliability even during power outages. This accuracy and dependability make it ideal for critical applications in industrial settings, laboratories, and HVAC systems.
Rugged Industrial ConstructionBuilt for durability, the gauge features a die-cast aluminum case, silicone seals, and a clear acrylic lens, all protected by IP54 equivalent enclosure. The externally accessible zero adjustment screw allows for fast onsite recalibration. This construction makes it suitable for both indoor and sheltered outdoor installations, resisting dust and occasional splashes.
Easy Installation and Versatile MountingDesigned for surface or flush mounting, the gauge includes all necessary accessories: mounting adapters, plugs, screws, and user instructions. Its 1/8" NPT female ports ensure simple connection to process lines, while the standard 4-inch diameter allows for easy integration into control panels or equipment. The full-view acrylic lens guarantees clear readability from various angles.
FAQ's of Dwyer USA Magnehelic Gauges .05-0-.2 Inch WC:
Q: How do I install the Dwyer Magnehelic Gauge Model 2000-0-0.2?
A: Installation is straightforward: mount the gauge vertically on a flat surface or flush with a panel using the included adapters and screws. Connect your process lines to the 1/8" NPT female ports. Ensure the device is at eye-level for optimal readability and verify proper zeroing after installation using the external adjustment screw.
Q: What media can this Magnehelic Gauge measure pressure in?
A: This model is designed to accurately measure differential pressures for steam, oil, and gas applications. It is ideal for industrial processes where it is important to monitor small pressure changes across filters, clean rooms, or ducts.
Q: When should I adjust the zero setting on the gauge?
A: Zero adjustment is recommended after installation, if the gauge is relocated, or periodically during routine maintenance to ensure continued accuracy. The external zero adjustment screw allows for quick corrections without disassembling the gauge.
Q: Where can the Magnehelic Gauge be used?
A: The gauge is suitable for use in industrial environments, HVAC applications, laboratories, and process monitoring panels, both indoors and in sheltered outdoor locations, thanks to its IP54 equivalent enclosure protection and durable construction.
Q: What benefits does the instantaneous mechanical response offer?
A: The gauge provides real-time pressure readings without lag, which is essential for critical applications where immediate monitoring of pressure fluctuations can prevent equipment damage or process interruptions.
Q: How is the reading displayed on this Magnehelic Gauge?
A: Pressure differentials are indicated on a large, full-view analog dial, with a white plastic background and black/red markings, enabling easy and quick reading by operators in varied lighting conditions.
Q: What maintenance is required for ongoing accurate operation?
A: Regular maintenance includes occasional zero adjustment, periodic inspections for dust or moisture ingress, and verifying the tightness of process connections. The rugged design minimizes routine maintenance needs.
