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.

Precision and Reliability in Industrial Applications

With a measurement range of 0 to 8.0 inch WC and an accuracy of 2% of full scale, the Magnehelic Gauge ensures reliable readings in critical environments. Its diaphragm sensor and analog display make it ideal for monitoring low-pressure differentials in systems using steam, oil, or gas.

Robust Construction and Flexible Mounting

Housed in a die-cast aluminum case with a black semi-gloss finish, this gauge offers both durability and a professional appearance. Accessories included support both surface and flush mounting, enabling straightforward installation tailored to your application's needs.

User-Friendly Operation and Maintenance

Featuring an external zero adjustment screw, the Magnehelic Gauge allows for easy calibration without disassembly. The clear acrylic window provides unobstructed viewing, and routine maintenance is simple due to the readily accessible components and IP54-rated enclosure.

FAQ's of Dwyer USA Magnehelic Gauges 0 To 8.0 Inch WC:

Q: How do I install the Dwyer Magnehelic Gauge for accurate measurement?

A: To ensure precise readings, install the gauge using the supplied mounting accessories for either surface or flush mounting. Make secure connections with the 1/8 NPT brass fittings, and use the included adapters for compatibility with rubber tubing as needed. Position the gauge vertically for the most consistent results.

Q: What types of media can this Magnehelic Gauge measure?

A: This gauge is designed to measure the pressure of steam, oil, and gas, making it suitable for various industrial process monitoring applications. Its diaphragm sensor is compatible with these media within the specified range.

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

A: Use the external zero adjustment screw when the gauge pointer drifts from zero while in a no-pressure state. This ensures measurement accuracy, particularly after installation, maintenance, or incident vibration.

Q: Where is the best place to mount the Magnehelic Gauge in an industrial setting?

A: Mount the gauge in an accessible location near the point of measurement, ensuring the case is orientated vertically. Both surface and flush mounting options are provided, giving flexibility for installation on control panels, walls, or equipment surfaces.

Q: What is the process for maintaining and cleaning the gauge?

A: Regularly inspect the gauge for dust and moisture. Clean the acrylic window with a soft, damp cloth. Ensure all pressure connections remain secure and leak-free. Periodically check the zero setting using the external adjustment screw for calibration.

Q: How does the gauge benefit industrial operations?

A: The gauge provides timely, precise monitoring of differential pressures, helping operators maintain optimal system performance and quickly identify issues. Its robust construction and easy maintenance lower downtime and replacement frequency.

Q: What protection does the IP54 rating provide for the gauge?

A: The IP54 enclosure rating means the gauge is protected against limited dust ingress and water splashes from any direction, making it reliable for typical industrial environmental conditions.
