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.

Its analog display and high accuracy facilitate immediate insight into your systems air or gas flow conditions.

Durable Design and Easy Installation

Constructed from precision-machined, die-cast aluminum with a black corrosion-resistant finish, this gauge is built to withstand industrial environments. The package includes mounting brackets, screws, and a user instruction sheet, supporting either panel or surface mounting for maximum installation flexibility.

FAQs of Dwyer USA Magnehelic Gauges 2-0-2 Inch WC:

Q: How is the Dwyer Magnehelic Gauge Model 2000-2 installed?

A: The gauge can be mounted on either a panel or a surface using the supplied mounting brackets and screws. Detailed installation instructions are included with the product to ensure proper setup.

Q: What types of pressure can this gauge measure?

A: This model is designed to measure low differential pressures of air and non-combustible gases, making it ideal for HVAC monitoring, clean rooms, and other environments where accurate air pressure readings are required.

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

A: The external zero adjustment screw in the cover should be used when the gauge indicates a reading other than zero under no pressure conditions, ensuring accuracy before routine monitoring.

Q: Where are the pressure connections located on this gauge?

A: Both high and low pressure ports are positioned at the rear of the unit, utilizing 1/8 NPT threaded connections for secure attachment to your system.

Q: What benefits does the IP52 case protection provide?

A: The IP52 rating ensures limited protection against dust and resistance to drops of water, making the gauge suitable for general indoor industrial settings without exposure to heavy moisture or excessive particulates.

Q: How quickly does the gauge respond to pressure changes?

A: Thanks to its mechanical diaphragm sensor, the Magnehelic Gauge provides an instantaneous response to differential pressure variations, allowing for real-time monitoring.
