About Dwyer 2203 Magnehelic Differential Pressure Gauge 0-3 PSI

Dwyer 2203 Magnehelic Differential Pressure Gauge 0-3 PSI

Model: 2203 Differential Pressure Gage, Range 0-3 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 2203 MAGNEHELIC, DIFFERENTIAL PRESSURE GAUGE, 0-3 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.

Precise and Reliable Differential Pressure Measurement

Engineered for industrial use, the Dwyer 2203 Magnehelic Gauge delivers accurate measurements of low differential pressures in HVAC systems, clean rooms, and filter monitoring. Its robust construction and instantaneous response time support continuous monitoring in tough environments, while the external adjustment feature enhances calibration convenience.

Flexible Installation and Easy Operation

The gauge comes equipped with side connections, a full-face easy-to-read acrylic scale, and offers surface, flush, or pipe mounting options. The included mounting brackets and screws, along with a clear instruction manual, make installation straightforward for installers and maintenance teams alike.

FAQs of Dwyer 2203 Magnehelic Differential Pressure Gauge 0-3 PSI:

Q: How do I calibrate the Dwyer 2203 Magnehelic Differential Pressure Gauge?

A: Calibration is performed through the external adjustment screw located on the front of the gauge. This feature allows for quick zeroing without disassembling the unit, ensuring ongoing accuracy even after installation.

Q: What types of media can the Dwyer 2203 Magnehelic measure?

A: This gauge is designed to measure air and compatible non-combustible gases only. It is not suitable for liquid or hazardous gas applications.

Q: When should the gauge be used in filter monitoring applications?

A: Use the Magnehelic 2203 to detect changes in pressure drop across filters. An increase in reading may indicate clogging, prompting timely filter maintenance or replacement to maintain optimal system performance.

Q: Where can the gauge be installed?

A: The Magnehelic 2203 supports surface mounting as standard, but flush and pipe mounting configurations are also available. Its compact 4-inch (101 mm) diameter fits a range of panel or wall installations.

Q: What makes the Dwyer 2203 Magnehelic suitable for clean room environments?

A: Its high accuracy, instantaneous response, and clean, analog display make it ideal for sensitive areas like clean rooms, where precise monitoring of air pressure differentials is essential.

Q: How does the gauge benefit HVAC systems?

A: By providing continuous and accurate pressure differential readings, the gauge helps ensure that ventilation, filtration, and airflow systems operate efficiently, reducing downtime and supporting environmental compliance.
