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-Precision Differential Measurement

The Dwyer Magnehelic Gauge is crafted for accurate and reliable differential pressure readings across air and noncorrosive gases. With a 2% full-scale accuracy and a clear analog display, users can confidently monitor critical parameters in real time. Suitability for HVAC, filtration, and clean room applications underscores its versatility and dependability.

Designed for Tough Industrial Environments

Encased in a heavy-duty die-cast aluminum housing and finished in black, the gauge is engineered to withstand rugged use. Its IP54 rating protects against dust and splashing water, while the silicone rubber seal ensures lasting durability. Operating temperature flexibility (-7C to +60C) allows deployment in a wide range of settings.

Simple Installation & Maintenance

Installation is easy with included accessories such as a mounting bracket, NPT plugs, and self-tapping screws. External zero adjustment allows for quick calibration, and the units flush or surface mounting capability ensures fit in tight or unique locations. The comprehensive instruction manual guides users through each step.

FAQs of Dwyer USA Magnehelic Gauges 0 To 10 Inch WC:

Q: How do I install the Dwyer Magnehelic Gauge in my system?

A: The gauge can be surface or flush mounted using the included bracket, screws, and NPT plugs. Simply connect the high and low pressure ports (1/8" NPT female) to your air or gas lines as per the instruction manual, then secure the unit in place on your panel or wall.

Q: What types of pressures and gases can the Magnehelic Gauge measure?

A: This gauge accurately measures differential pressure of air and noncorrosive gases with a scale range of 0 to 10 inch WC, handling pressures up to 15 psi (1.03 bar) safely. Avoid using with corrosive gases or liquids for optimal performance and longevity.

Q: When should I use the external zero adjustment feature?

A: Use the external screw zero adjustment whenever you notice the needle is not resting at zero under no differential pressure conditions. This feature simplifies calibration and ensures ongoing measurement accuracy without disassembly.

Q: Where can the Magnehelic Gauge be installed for best results?

A: Install the gauge in areas where ambient temperatures range from -7C to +60C and it is not exposed to excessive moisture, as it is rated IP54. Its compact 4-inch design and mounting options make it suitable for panels, walls, or equipment housings in various industrial settings.

Q: What are the benefits of choosing a diaphragm-based, analog differential gauge like this?

A: Diaphragm technology allows for sensitive and precise readings, while analog display offers immediate visualization of pressure differences. The robust build ensures reliability, and low maintenance requirements make it suitable for continuous industrial monitoring.

Q: How does the gauge protect itself against overpressure?

A: The Dwyer Magnehelic Gauge is designed to withstand overpressures up to its rated pressure (15 psi/1.03 bar), ensuring safety and durability without compromising performance or accuracy.
