About Dwyer USA Magnehelic Gauges 0 To 5.0 Inch WC

Dwyer USA Magnehelic Gauges 0 To 5.0 Inch WC

Model	Description
2005	Differential pressure gage, range 0-5.0" w.c., minor divisions .10.

The industry standard in indicating low air or gas pressures of positive, negative, or differential pressures.

Large, easy-to-read 4" (102 mm) dial.

No manometer fluid to evaporate, freeze, or cause toxic or leveling problems.

INCLUDES

Two 1/8" NPT plugs, two 1/8" rubber tubing adapters, and three mounting adapters with screws

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.

Versatile Differential Pressure Measurement

Engineered for precision, the Magnehelic Gauge accurately measures differential pressure in various industrial applications, including HVAC, clean rooms, and filter monitoring. Its 0 to 5.0 inch WC range and fine graduations guarantee reliable and easy-to-read results, enhancing operational safety and system efficiency.

Robust Build for Industrial Environments

Constructed with a die-cast aluminum case and acrylic cover, this gauge is designed for durability. The silicone diaphragm and IP52-rated enclosure offer protection against dust and limited moisture. Its black epoxy finish resists corrosion, making it suitable for long-term use in demanding conditions.

Quick Installation and Adjustment

With surface or flush mount options and included accessories, setup is straightforward. The external adjustment screw allows users to conveniently zero the device without dismantling it. Versatile pressure connection placements (side or back) further simplify installation to fit different system requirements.

FAQ's of Dwyer USA Magnehelic Gauges 0 To 5.0 Inch WC:

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

A: To install the Magnehelic Gauge, mount it vertically using the provided surface or flush mount accessories. Choose the side or back 1/8 NPT pressure connection that best suits your layout, and use the included plugs and adapters to connect rubber tubing as required. Ensure it's securely fitted to maintain accurate differential pressure readings.

Q: What type of media can the Magnehelic Gauge measure pressure for?

A: This model is suitable for measuring differential pressure in steam, oil, and gas systems, making it ideal for a range of industrial applications such as HVAC, filter monitoring, and clean room environment control.

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

A: You should use the external zero adjustment screw periodically or whenever you notice a deviation from zero reading with no pressure applied. This ensures ongoing accuracy and reliability of the gauge without disassembly.

Q: Where is the best place to mount the Magnehelic Gauge?

A: The gauge is designed for vertical mounting on surfaces or panels, typically near or on the equipment you are monitoring. Select a location protected from direct water exposure and vibration to ensure accurate and stable readings.

Q: What benefits does the quick response time provide?

A: With a response time of less than one second, the Magnehelic Gauge delivers real-time pressure readings. This allows for immediate detection of pressure changes, enabling quick system adjustments and improved process safety.

Q: How do I maintain the Magnehelic Gauge for long-term use?

A: Periodically verify the zero setting, check connections for leaks, and clean the acrylic cover as needed. Since the gauge features a silicone diaphragm and durable finish, routine inspection helps maintain accuracy and extend product life.
