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 20 Inch WC:

Q: How do I install the Dwyer USA Magnehelic Gauge for optimal performance?

A: Installation is straightforward: choose a surface or flush mount location, use the included plugs and adapters, and connect via the 1/8 NPT threads. Ensure the gauge is mounted upright and use mounting screws supplied for stability.

Q: What types of media can be measured with this Magnehelic Gauge?

A: This gauge is designed to measure pressure of steam, oil, or gas, aligning with a variety of industrial requirements for monitoring these common process fluids.

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

A: Use the external adjustment screw to zero the gauge whenever the pointer does not align with zero under no pressure conditions, ensuring continued measurement accuracy.

Q: Where can I safely operate this gauge in terms of temperature and pressure?

A: The gauge can be safely used in environments with temperatures ranging from -20C to +60C (-4F to +140F), and withstands pressures up to 15 psi (1.03 bar), thanks to its robust construction and overpressure blowout protection.

Q: What steps ensure accurate readings throughout operation?

A: Regularly verify the zero point using the external screw, prevent overpressurization by monitoring process conditions, clean the gauge lens for clear visibility, and check all connections for leaks.

Q: What are the key benefits of using the Dwyer Magnehelic Gauge in industrial applications?

A: Key benefits include rapid response, straightforward analog reading, high-grade materials for longevity, overpressure safety measures, and versatile mounting options-all supporting reliable day-to-day operation in industrial environments.
