About Dwyer 2204 Magnehelic Differential Pressure Gauge 0-4 PSI

Dwyer 2204 Magnehelic Differential Pressure Gauge 0-4 PSI

Model: 2204 Differential Pressure Gage, Range 0-4 PSI, Minor Divisions .10.

Bezel provides Flange For Flush Mounting in Panel. Clear Plastic Face is Highly Resistant to Breakage. Provides Undistorted Viewing of Pointer and Scale.

Dwyer 2204 MAGNEHELIC, DIFFERENTIAL PRESSURE GAUGE, 0-4 PSI

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.

Versatile Differential Pressure Measurement

The Dwyer 2204 Magnehelic Gauge is engineered for accurate differential pressure monitoring, suitable for HVAC, clean rooms, filter monitoring, and general industrial uses. Its analog display and high-contrast white aluminum dial ensure clear visibility, while the 0-4 PSI range delivers precise readings for air and non-corrosive gases. The units durable construction and compact design provide effortless installation and long-term reliability in demanding environments.

Robust Industrial Grade Construction

Crafted with a die-cast aluminum case and clear acrylic cover, the Dwyer 2204 is built to withstand industrial conditions. The black finish resists wear, and the silicone rubber seal offers reliable performance across a temperature range of -7C to 60C. It includes a mounting bracket, NPT plugs, and adapters, allowing flexible installation on surfaces or panels for maximum application versatility.

FAQs of Dwyer 2204 Magnehelic Differential Pressure Gauge 0-4 PSI:

Q: How is the Dwyer 2204 Magnehelic Differential Pressure Gauge installed?

A: The gauge can be surface or flush mounted using the supplied mounting bracket, three adapters, and two 1/8" NPT plugs. Side and back connections (1/8" NPT female) facilitate straightforward integration into ductwork or equipment.

Q: What types of media can the Dwyer 2204 measure pressure for?

A: This gauge is designed to measure the pressure of air and non-corrosive gases only. It should not be used with corrosive or liquid substances, as it features a sensitive diaphragm sensor.

Q: When should I use the Dwyer 2204 for filter or duct monitoring?

A: Use this Magnehelic gauge when you require accurate, real-time pressure readings across HVAC filters, fans, or clean room barriers. It is especially useful to indicate filter condition or system pressure drops, ensuring timely maintenance and efficient operation.

Q: Where can the Dwyer 2204 Magnehelic Gauge be used?

A: This gauge is suitable for installation in industrial and commercial environments, including monitoring of clean rooms, HVAC systems, air ducts, and ventilation applications throughout India and worldwide.

Q: What is the process for maintaining and calibrating the Dwyer 2204?

A: Periodic inspection is recommended to ensure the integrity of connections and the acrylic cover. Cleaning the cover and dial with a non-abrasive cloth maintains visibility. Calibration should be performed according to industrial standards or factory recommendations to ensure measurement accuracy.

Q: What are the benefits of using a diaphragm-type analog gauge like the Dwyer 2204?

A: The diaphragm sensor provides accurate, stable readings with minimal drift, while the high-contrast analog dial allows quick assessment at a glance. Its robust mechanical design ensures reliability even in demanding industrial settings.
