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.

FAQs of Dwyer USA Magnehelic Gauges 0 To 80 Inch WC:

Q: How can I install the Dwyer Magnehelic 2000-80 gauge?

A: You can install the gauge using the included flush mounting adaptors and self-tapping screws. It supports both surface and flush mounting orientations, with connections provided through 1/8" NPT female high and low pressure fittings on the side and back. Vertical mounting is recommended for optimal performance.

Q: What substances can be safely measured with this Magnehelic gauge?

A: The Dwyer Magnehelic 2000-80 is designed for measuring the pressure of air and non-corrosive gases. It is best not to use it with corrosive gases or liquids to prevent sensor or material damage.

Q: When should I use the zero adjustment screw on my gauge?

A: Utilize the external adjustment screw to recalibrate the zero point of your gauge if it drifts due to environmental changes or after installation, ensuring accurate readings. Always perform zero calibration with the pressure ports open to atmospheric pressure.

Q: Where is the Magnehelic 2000-80 commonly used?

A: This gauge is frequently employed in monitoring air velocity, filter resistance in HVAC systems, and pressure differentials in ducts, rooms, and building compartments. Industries such as manufacturing, pharmaceutical, and facility management often use it for pressure monitoring tasks.

Q: What are the benefits of using a precision-engineered analog gauge like this model?

A: The analog Magnehelic gauge offers visual clarity, high accuracy, and resilience in harsh environments. Its robust construction, easy maintenance, and external zero adjustment provide users with reliable, long-term operation without the need for complex electronics.

Q: How do I maintain the Dwyer Magnehelic gauge for long-term accuracy?

A: Regularly inspect the gauge for dust or debris on the viewing window, verify zero calibration, and ensure the pressure connections are free from blockages. Do not exceed the recommended overpressure limit (15 psig) to maintain integrity and accuracy.
