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.

FAQs of Dwyer USA Magnehelic Gauges 10-0-10 MM WC:

Q: How is the Dwyer Magnehelic Gauge installed in HVAC systems?

A: The gauge supports surface, flush, or portable mounting using the supplied bracket and hardware. It features 1/8 NPT side and back connections for flexible placement within your HVAC ductwork or equipment panels.

Q: What is the recommended process for zero adjustment on this gauge?

A: The Magnehelic Gauge offers an external zero adjustment screw. To calibrate, isolate the gauge from pressure, release to atmospheric pressure, and use the provided screw to align the pointer to zero for accurate future readings.

Q: When should I use this gauge for filter or clean room monitoring?

A: Use the Magnehelic Gauge when you need to monitor low differential pressure, such as across HVAC filters or between clean and less-controlled spaces. Monitoring helps detect filter clogging or maintain environmental integrity in critical areas.

Q: What types of gases can be measured with this gauge?

A: This gauge is designed to measure air and other compatible, non-corrosive gases, making it suitable for a wide range of industrial and laboratory applications.

Q: Where is this gauge typically used in industrial setups?

A: It is commonly installed in HVAC systems, clean rooms, laboratories, and any environment requiring precision air pressure monitoring, such as air velocity measurement points or filter assemblies.

Q: How does the precision-machined construction benefit users?

A: Precision-machined construction ensures consistent measurement accuracy, minimal drift over time, and reliable long-term service, ultimately reducing downtime and maintenance in critical applications.

Q: What standard accessories are included with this gauge?

A: Each unit comes with mounting screws, two 1/8 NPT pipe plugs, brass terminal nuts, a mounting bracket, and a detailed instruction manual for straightforward installation and use.
