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.

Reliable Differential Pressure MeasurementFeaturing a factory-calibrated diaphragm sensor, the Dwyer Magnehelic Gauge assures accuracy and reliability for monitoring pressures in a range of HVAC and process air applications. Its analog display provides clear readings, and the sturdy enclosure ensures durability even in demanding industrial environments. External zero adjustment allows for quick recalibration, reducing downtime and maintaining measurement confidence.
Flexible Installation and AccessoriesDesigned for convenience, each gauge comes complete with mounting adapters, screws, 1/8 NPT plugs, and tubing adapters. The standard vertical orientation can be factory calibrated for alternate positions, enhancing installation flexibility. Its 4-inch acrylic window and white aluminum dial allow easy readability from a distance, making it user-friendly for operators in busy settings.
Dependable Performance in Varied ConditionsWith a wide operating temperature range from -7C to 60C (20F to 140F) and an overpressure limit of 15 psi, the Magnehelic Gauge performs reliably in a variety of environmental conditions. The IP54 rated enclosure resists splashes, and high-quality materials ensure long service life and consistent performance in industrial applications.
FAQs of Dwyer USA Magnehelic Gauges 0 To 2.0 Inch WC:
Q: How do I install the Dwyer Magnehelic Gauge for accurate pressure readings?
A: For optimal accuracy, mount the gauge in a vertical orientation (standard), using the provided adapters and screws. If installation requires a different position, request factory calibration for that orientation. Connect the 1/8 NPT female ports to compatible tubing or pipe using supplied adapters, and ensure the seals are tight to avoid leaks.
Q: What process should I follow to recalibrate the zero setting on this gauge?
A: To recalibrate, use the external adjustment screw located on the gauges face. Ensure that both pressure ports are open to atmospheric pressure, then turn the screw until the pointer aligns with zero on the scale. This helps maintain measurement accuracy after installation or over time.
Q: When should I use the Magnehelic Gauge in industrial applications?
A: This gauge is best used when precise measurement of low differential pressures is needed, such as in monitoring air filters, clean rooms, HVAC systems, and ventilation setups. Its robust construction and immediate response time make it ideal for continuous monitoring in demanding environments.
Q: Where is this product commonly installed within Indian industrial facilities?
A: Dwyer Magnehelic Gauges are widely used across manufacturing plants, pharmaceutical facilities, HVAC system panels, process control rooms, and laboratory air monitoring systems throughout India for monitoring and maintaining air pressure within safe limits.
Q: What benefits does the IP54 enclosure rating provide in industrial environments?
A: The IP54 rating ensures the gauge is resistant to dust ingress and water splashes, safeguarding sensitive internal components. This enhances operational reliability and prolongs the service life of the gauge in environments where moisture or particulate contamination might occur.
Q: How does the gauge display and measure pressure effectively?
A: The analog display features a fire-orange polycarbonate pointer on a clearly marked white aluminum dial for high visibility. The diaphragm sensor provides accurate differential pressure readings of air or non-corrosive gases, with an accuracy of 2% full scale, and offers instantaneous response for real-time monitoring.
