About Dwyer USA Magnehelic Gauges 0 To 100 MM WC

Dwyer USA Magnehelic Gauges 0 To 100 MM WC

Select the Magnehelic gage for high accuracy--guaranteed within 2% of full scale

and for the wide choice of 81 models

available to suit your needs precisely. Using Dwyer's simple, frictionless Magnehelic

gage movement, it quickly

indicates low air or non-corrosive gas pressures--either positive, negative (vacuum) or

differential. The design resists

shock, vibration and over-pressures. No manometer fluid to evaporate, freeze or cause

toxic or leveling problems.

It's inexpensive, too.

The Magnehelic gage 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. It also checks gas-air ratio controls and

automatic valves, and monitors blood and respiratory

pressures in medical care equipment.

Note: May be used with Hydrogen. Order a Buna-N diaphragm.

Pressures must be less than 35 psi.

Bezel provides flange for flush mounting in panel.

Clear plastic face is highly resistant to breakage. Provides undistorted viewing of pointer and scale.

Precision litho-printed scale is accurate and easy to read.

Red tipped pointer of heat treated aluminum tubing is easy to see. It is rigidly mounted on the helix shaft.

Pointer stops of molded rubber prevent pointer over-travel without damage.

"Wishbone" assembly provides mounting for helix, helix bearings and pointer shaft.

Jeweled bearings are shock-resistant mounted; provide virtually friction-free motion for helix. Motion damped with high viscosity silicone fluid.

Zero adjustment screw is conveniently located in the plastic cover, and is accessible without removing the cover. O-ring seal provides pressure tightness.

Helix is precision made from an alloy of high magnetic permeability. Mounted in jeweled bearings, it turns freely, following the magnetic field to move the pointer across the scale.

Samarium Cobalt magnet mounted at one end of range spring rotates helix without mechanical linkages.

Calibrated range spring is flat spring steel. Small amplitude of motion assures consistency and long life. It reacts to pressure on diaphragm. Live length adjustable for calibration.

Silicone rubber diaphragm with integrally molded O-ring is supported by front and rear plates. It is locked and sealed in position with a sealing plate and retaining ring. Diaphragm motion is restricted to prevent damage due to overpressures.

Die cast aluminum case is precision made and iridite-dipped to withstand 168 hour salt spray corrosion test. Exterior finished in baked dark gray hammerloid. One case size is used for all standard pressure options, and for both surface and flush mounting.

Blowout plug of silicone rubber protects against overpressure on 15 psig rated models. Opens at approximately 25 psig.

O-ring seal for cover assures pressure integrity of case.

Applications

Filter Monitoring

Air Velocity with Dwyer Pitot Tube

Blower Vacuum Monitoring

Fan Pressure Indication

Duct, Room or Building Pressures

Clean Room Positive Pressure Indication

Precision Monitoring for Demanding Applications

The Dwyer Magnehelic Gauge excels in maintaining precise differential pressure measurement across HVAC systems, clean rooms, and filter monitoring setups. It delivers reliable performance in both industrial and commercial settings, ensuring that you can monitor vital system pressures with confidence. Its analog display allows for straightforward readings, while the 2% accuracy keeps your operations within optimal parameters.

Robust Construction and Flexible Installation

Crafted from die-cast aluminum with a powder-coated finish, the gauge is built to handle demanding environments. The IP52 protection safeguards against dust and minor moisture exposure. Installation is flexible, featuring both flush and surface mounting options and standard 1/8" NPT pressure connections. The clear acrylic window and external zero adjustment enhance usability and maintenance.

FAQ's of Dwyer USA Magnehelic Gauges 0 To 100 MM WC:

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

A: The Magnehelic Gauge can be mounted using the included hardware for either flush or surface installation. Use the 1/8" NPT high and low pressure taps-available on both the side and back-for secure connection to your systems. Detailed instructions are included with each unit.

Q: What types of media can this differential pressure gauge measure?

A: This gauge is designed for measuring the pressure of non-corrosive gases, steam, and oil, making it suitable for a wide range of HVAC, clean-room, and process monitoring applications.

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

A: If the pointer does not return to zero when no pressure is applied, use the external screw to recalibrate the gauge. This ensures ongoing accuracy and reliable pressure monitoring.

Q: Where can the Magnehelic Gauge be utilized for optimal benefit?

A: Optimal applications include HVAC systems, clean rooms, filter monitoring, fan and blower pressure checks, and systems where precise low-pressure monitoring is vital for safety and efficiency.

Q: What is the maximum pressure this gauge can safely withstand?

A: The Magnehelic Gauge can safely handle a continuous overpressure and maximum operating pressure of 15 psi (1.03 bar), ensuring durability and longevity in typical usage scenarios.

Q: How does the Magnehelic Gauge maintain accuracy in challenging environments?

A: Its construction features a silicone rubber seal, die-cast aluminum case, and acrylic lens, which together with precision calibration, provide resilience and reliable measurement even in challenging temperature ranges from -7C to +60C.
