The industry standard in indicating low air or gas pressures of positive, negative, or differential pressures.

Large, easy-to-read 4" (102 mm) dial.

No manometer fluid to evaporate, freeze, or cause toxic or leveling problems.

INCLUDES

Two 1/8" NPT plugs, two 1/8" rubber tubing adapters, and three mounting adapters with screws

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.

Versatile Pressure Monitoring

This Magnehelic gauge is engineered for precision measurement of low differential pressures in gases, steam, and oil-crucial for applications like HVAC, clean rooms, and industrial processes. Its diaphragm sensor, along with both back and side connections, offers installation flexibility and reliable performance in various environments.

Easy Installation and Operation

With surface or flush mounting and straightforward 1/8 NPT connections, installation is quick and hassle-free. External zero adjustment ensures accurate readings, while included accessories-plugs, screws, and instructions-support a seamless setup. Its analog display is intuitive for users to read at a glance.

Industrial Durability and Safety

Constructed from die-cast aluminum with a powder-coated finish, this gauge is built to withstand demanding industrial settings. The overpressure blowout plug on the rear provides an extra layer of safety, and silicone rubber seals guarantee leak-resistant operation under maximum pressures up to 15 psi.

FAQ's of Dwyer USA Magnehelic Gauges 0 To 3.0 Inch WC:

Q: How do I install the Dwyer Magnehelic 2000 Series gauge?

A: The gauge can be installed using either surface or flush mounting, depending on your requirements. It features both side and back connections, compatible with 1/8 NPT threads. Mounting screws and plugs are included, and the detailed instruction sheet offers step-by-step guidance.

Q: What applications is this Magnehelic gauge suitable for?

A: It is ideal for HVAC systems, air and gas filter monitoring, damper and fan pressure indication, clean room pressure control, and other industrial scenarios requiring precise differential pressure measurement between 0 and 3.0 inch WC.

Q: When should I adjust the zero setting on the gauge?

A: You should adjust the external zero adjustment screw if the pointer does not rest at zero when no pressure is applied. This should be checked during initial installation, routine maintenance, or if the gauge experiences a substantial mechanical shock.

Q: What materials are used in the construction of the gauge?

A: The case is made of die-cast aluminum with a powder-coated finish. The cover and dial are acrylic, the pointer is aluminum, and all seals are silicone rubber, providing durability and resistance in industrial environments.

Q: How does the overpressure protection feature work?

A: The gauge has a blowout plug located on the rear that safely relieves excess pressure, protecting internal components and enhancing user safety in case of accidental overpressure situations.

Q: Where can this gauge be used with respect to environmental protection?

A: With an IP52 ingress protection rating, this gauge resists dust and dripping water. It's suitable for most indoor industrial environments, such as mechanical rooms or laboratory settings.

Q: What benefits does the analog display offer compared to digital models?

A: The analog dial provides real-time, at-a-glance pressure readings with no need for power supply or batteries, making it reliable and easy to integrate into existing industrial control systems.
