About Dwyer USA Model 2040 Magnehelic Gage Range 0-40 Inch WC

Dwyer USA Model 2040 Magnehelic Gage Range 0-40 Inch WC

Description

Dwyer 2040 Differential pressure gage, range 0-40" w.c. (inches of water), minor divisions 1.0.

Using Dwyers simple, frictionless Magnehelic Gage movement, it quickly indicates low air or non-corrosive gas pressures--either positive, negative (vacuum) or differential. The design resists shock, vibration and over-pressures. No manometer fluid to evaporate, freeze or cause toxic or leveling problems. Its inexpensive, too.

The Magnehelic Gage 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. It also checks gas-air ratio controls and automatic valves, and monitors blood and respiratory pressures in medical care equipment.

Note:May be used with Hydrogen. Order a Buna-N diaphragm. Pressures must be less than 35 psi.

Features

Bezel provides flange for flush mounting in panel.

Clear plastic face is highly resistant to breakage. Provides undistorted viewing of pointer and scale.

Precision litho-printed scale is accurate and easy to read.

Red tipped pointer of heat treated aluminum tubing is easy to see. It is rigidly mounted on the helix shaft.

Pointer stops of molded rubber prevent pointer over-travel without damage.

"Wishbone" assembly provides mounting for helix, helix bearings and pointer shaft.

Jeweled bearings are shock-resistant mounted; provide virtually friction-free motion for helix. Motion damped with high viscosity silicone fluid.

Zero adjustment screw is conveniently located in the plastic cover, and is accessible without removing the cover. O-ring seal provides pressure tightness.

Helix is precision made from an alloy of high magnetic permeability. Mounted in jeweled bearings, it turns freely, following the magnetic field to move the pointer across the scale.

Samarium Cobalt magnet mounted at one end of range spring rotates helix without mechanical linkages.

Calibrated range spring is flat spring steel. Small amplitude of motion assures consistency and long life. It reacts to pressure on diaphragm. Live length adjustable for calibration.

Silicone rubber diaphragm with integrally molded O-ring is supported by front and rear plates. It is locked and sealed in position with a sealing plate and retaining ring. Diaphragm motion is restricted to prevent damage due to overpressures.

Die cast aluminum case is precision made and iridite-dipped to withstand 168 hour salt spray corrosion test. Exterior finished in baked dark gray hammerloid. One case size is used for all standard pressure options, and for both surface and flush mounting.

Blowout plug of silicone rubber protects against overpressure on 15 psig rated models. Opens at approximately 25 psig.

O-ring seal for cover assures pressure integrity of case.

Industrial Versatility and Precision

The Dwyer Model 2040 Magnehelic Gage delivers reliable measurements for a broad array of industrial applications, including filter monitoring, clean room pressure, HVAC duct and fan pressure, and furnace draft. Designed for immediate response, its mechanical analog display ensures quick and precise readings of air and non-corrosive gas differentials, enhancing process control and maintenance efficiency.

Robust Construction for Demanding Environments

Built with a die-cast aluminum body and a powder-coated finish, the Magnehelic 2040 is engineered to withstand industrial rigors. Its clear acrylic lens and IP52 ingress protection defend against dust and occasional water, making it a robust tool for tough settings. The included mounting kits and flexible installation options cater to both panel and surface applications, streamlining setup.

FAQs of Dwyer USA Model 2040 Magnehelic Gage Range 0-40 Inch WC:

Q: How does the Model 2040 Magnehelic Gage operate?

A: The Model 2040 Magnehelic Gage uses a diaphragm differential pressure sensor to mechanically indicate pressure changes between two points. As air or non-corrosive gas flows across the sensing diaphragm, the resultant movement is transmitted to a dial pointer, providing immediate and accurate analog measurement.

Q: What steps should I follow to install and calibrate the Magnehelic Gage?

A: This gage is designed for vertical mounting and comes with mounting hardware, panel mounting screws, pressure fittings, and adaptors. For calibration, use the external zero adjustment screw. Detailed installation and adjustment procedures are included in the instruction manual provided with the unit.

Q: Where is the Dwyer Model 2040 most beneficially used?

A: Typical applications include HVAC systems for filter monitoring, clean room pressure management, monitoring duct static pressure, measuring fan and blower performance, assessing air velocity, and ensuring correct furnace draft. It is particularly valuable where immediate, accurate differential pressure readings are essential.

Q: What are the advantages of using a mechanical indication gauge like the Model 2040?

A: A mechanical gauge provides real-time readings with no power source required, ensuring continued operation even during power outages. Its analog dial display is straightforward to read, and the robust construction supports reliable performance in industrial environments.

Q: How can overpressure events be managed with this device?

A: The Model 2040 features protection up to its maximum rated pressure of 15 PSI (1.034 bar), safeguarding the sensor and internal components in unexpected overpressure situations. However, exceeding this limit repeatedly should be avoided to maintain long-term accuracy.

Q: What maintenance does the Magnehelic 2040 require for optimum performance?

A: Routine checks include verifying zero calibration, ensuring the gauge is free of dust and moisture, and inspecting pressure fittings for secure connections. The clear acrylic lens can be wiped clean, and detailed maintenance steps are outlined in the supplied manual.
