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.

FAQ's of Dwyer USA Magnehelic Gauges 0 To 80 Inch WC:

Q: How do you install the Dwyer Magnehelic Gauge in panel or flush mounting applications?

A: Installation is simple-use the included mounting hardware and follow the panel or surface mounting instructions. Thread the two 1/8" NPT female ports to your system's high and low pressure taps. All necessary pipe plugs and screws are provided for secure, reliable mounting.

Q: What substances can the Magnehelic Gauge measure pressure for?

A: This gauge is designed for differential pressure measurements in steam, oil, and gas systems. It is suitable for industrial environments where these media are present and is engineered according to ASTM D4393 standards.

Q: When should external zero adjustment be performed?

A: Zero adjustment should be done before the initial operation and periodically during routine maintenance. This ensures continued accuracy by compensating for any mechanical drift that may occur over time.

Q: Where is this gauge best used within industrial applications?

A: The Magnehelic Gauge is ideal for applications requiring differential pressure monitoring across filters, blowers, or ventilation lines in steam, oil, and gas processing plants, as well as HVAC and cleanroom environments.

Q: What process does the gauge use to measure differential pressure?

A: It uses a mechanical diaphragm mechanism connected to a helix, translating pressure differences into movement of the analog display pointer for real-time, accurate monitoring.

Q: How does the gauge benefit industrial operations?

A: It helps ensure process safety and efficiency by providing quick, reliable pressure readings, facilitating preventative maintenance, and reducing costly system downtime.

Q: What is included with the Dwyer Magnehelic Gauge upon purchase?

A: The package includes the gauge, mounting hardware, two 1/8" NPT pipe plugs, and self-tapping screws, making installation straightforward and comprehensive for immediate use.
