The industry standard in indicating low air or gas pressures of positive, negative, or differential pressures.

Large, easy-to-read 4" (102 mm) dial.

No manometer fluid to evaporate, freeze, or cause toxic or leveling problems.

INCLUDES

Two 1/8" NPT plugs, two 1/8" rubber tubing adapters, and three mounting adapters with screws

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.

Versatile Pressure Measurement

The Dwyer Magnehelic Gauge 2000 Series is engineered for precise differential pressure monitoring across multiple industrial applications. Its robust construction and comprehensive mounting options make it suitable for installations in HVAC systems, clean rooms, and process industries.

Rugged and Accurate Design

Constructed with a die-cast aluminum case and an acrylic lens, the gauge delivers durability and consistent performance. The diaphragm sensing element provides accuracy within 2% of the full scale, supporting high reliability even in demanding monitoring scenarios.

User-Friendly Installation and Adjustment

Featuring an external zero adjustment screw and versatile mounting positions (surface or flush mount), the gauge ensures quick setup and recalibration. Complete accessory fittings, including compression connectors and mounting screws, simplify the installation process.

FAQ's of Dwyer USA Magnehelic Gauges 0 To 40 Inch WC:

Q: How do I adjust the zero point on the Dwyer Magnehelic Gauge 2000 Series?

A: The zero adjustment can be made externally using the adjustment screw located on the front bezel of the gauge. This allows for easy recalibration without disassembling the unit.

Q: What types of pressure media can this gauge safely measure?

A: The Dwyer Magnehelic Gauge 2000 Series is suitable for measuring the differential pressure of steam, oil, and gas, making it appropriate for a variety of industrial environments.

Q: When should a Magnehelic Gauge be used for filter monitoring or cleanroom pressure applications?

A: Use the gauge whenever it's critical to monitor and maintain specific pressure differentials, such as in HVAC filter monitoring, clean rooms for contamination control, or ducts to ensure proper air flow.

Q: Where can the gauge be mounted, and what are the mounting options?

A: The gauge offers both surface and flush mount options, permitting flexible placement on panels, walls, or dedicated enclosures as required by your application.

Q: What is the process for connecting the gauge to my existing system?

A: Connect the 1/8" NPT female ports (high and low) to your pressure source using the provided NPT plugs or compression fittings for 1/4" OD tubing, securing the unit with the supplied mounting screws.

Q: What are the primary benefits of using a Dwyer Magnehelic Gauge in industrial settings?

A: The gauge provides quick, accurate differential pressure readings crucial for equipment efficiency and safety. Its robust design withstands rigorous use, while precision-machined components minimize maintenance and downtime.

Q: How does the diaphragm sensing element enhance measurement reliability?

A: The diaphragm sensing element, unlike Bourdon tubes, responds sensitively to pressure differences, ensuring stable and precise analog readouts over the wide scale of 0 to 40 inches WC.
