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.

This gauge features a clear analog display, external zero adjustment screw for easy recalibration, and adaptable mounting optionssurface or panel mount. Package includes mounting screws, plastic tubing, and an instruction sheet for quick installation. Its 4-inch diameter and 1/8 NPT threaded connections provide compatibility with a range of systems, making integration straightforward in new or existing setups.

FAQs of Dwyer USA Magnehelic Gauges 0 To 150 Inch WC:

Q: How does the Dwyer Magnehelic Gauge measure pressure?

A: The Magnehelic Gauge uses a sensitive diaphragm to detect and display differential pressure between two points. The analog display, marked 0 to 150 Inch WC, shows precise readings of air or non-corrosive gas pressure, making it suitable for monitoring clean rooms, filtration systems, and air flow applications.

Q: What benefits does the external zero adjustment screw offer?

A: The external zero adjustment screw allows users to recalibrate the gauge without dismantling it. This feature ensures continued accuracy over time and extends the service life of the device, which is especially valuable during routine maintenance in industrial environments.

Q: When is this gauge ideal for use?

A: This Magnehelic Gauge is optimal for continuous monitoring in environments that require consistent air or gas pressure control, such as laboratories, clean rooms, HVAC systems, filter maintenance, and fume hood installations.

Q: Where should the Magnehelic Gauge be installed for optimal performance?

A: The gauge can be mounted on a surface or panel, depending on system requirements and available space. Proper placement ensures accurate differential pressure readings and easy access for observation and adjustment. Connection ports are located at the back or side, depending on the specific model.

Q: What is the process for installing the Dwyer Magnehelic Gauge?

A: Installation involves securing the gauge using provided mounting screws, attaching the plastic tubing to the 1/8 NPT connections, and following the instruction sheet for correct setup. After mounting, connect to the pressure source and use the external screw to set the reading to zero before use.

Q: How does the IP52 protection benefit the device?

A: IP52 protection ensures that the gauges front cover resists entry of dust and offers limited resistance to dripping water. This safeguards internal components in demanding industrial settings, helping prolong device life and maintain consistent, reliable performance.
