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.

Engineered for versatility, this Magnehelic Gauge can be surface or flush mounted in various industrial settings, including filtering systems, fan and blower monitoring, and clean room pressure measurement. Its 100 mm analog dial is easy to read and housed behind an acrylic lens, making it suitable for both daily operations and critical monitoring tasks where prompt detection of pressure variations is essential.

FAQs of Dwyer USA Magnehelic Gauges 0 To 40 Inch WC:

Q: How is the Dwyer 2000-40 Magnehelic Gauge installed and what ports does it use?

A: The Dwyer 2000-40 Magnehelic Gauge can be mounted either on a surface or flushed into a panel using the provided standard mounting bracket. It utilizes two 1/8" NPT pressure portsone for high and one for low pressurewhich connect to your differential pressure source.

Q: What are the typical applications for this differential pressure gauge?

A: This Magnehelic Gauge is designed for use in filter monitoring, fan and blower pressure measurement, clean room pressure, duct static pressure, and measuring pressure drop across orifice plates. It is suitable for use in industrial environments where monitoring air and compatible gases is critical.

Q: When should the external zero adjustment screw be used?

A: The external zero adjustment screw should be used during installation or when recalibrating the gauge to ensure the pointer rests exactly at zero under no pressure. This helps maintain accurate readings throughout the gauges service life.

Q: Where can the Dwyer Magnehelic Gauge be utilized?

A: This gauge is commonly installed in HVAC systems, clean rooms, industrial process setups, filter housings, and ductwork. Its robust, powder-coated aluminium case makes it appropriate for use in demanding industrial settings across India.

Q: What is the process for reading the pressure measurement on this gauge?

A: Simply observe the analog dial, which displays differential pressure from 0 to 40 inches of water column (WC). The black anodized aluminum pointer indicates the current pressure value against the clearly printed scale on the white acrylic dial.

Q: How does using the Dwyer Magnehelic Gauge benefit industrial operations?

A: This gauge helps ensure optimal performance by providing reliable, real-time pressure monitoring. It aids in detecting filter blockages, maintaining clean room standards, and verifying system integrity, contributing to efficient operations and reduced maintenance costs.
