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.

Reliable Differential Pressure Monitoring

The Dwyer 2203 Magnehelic Differential Pressure Gauge provides immediate and precise readings, empowering users to efficiently monitor air and non-corrosive gases. Its 03 PSI scale is well-suited for critical applications such as HVAC filter monitoring and maintaining optimal fan pressure. The externally accessible zero adjustment enables swift recalibration, ensuring ongoing accuracy and ease of maintenance.

Engineered for Durability and Versatility

Encased in robust die-cast aluminum with a black matte finish and protected by a clear acrylic lens, the 2203 Magnehelic gauge is built for longevity. It supports both surface and flush mounting to suit various installation environments. The design includes NPT female ports, silicone seals, and a white aluminum dial for clear visibility, emphasizing adaptability and low maintenance needs.

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

Q: How is the Dwyer 2203 Magnehelic Pressure Gauge typically installed?

A: The gauge is designed for vertical mounting, which is preferred for optimal accuracy. It can be installed on a surface or flush-mounted using the included adapters and screws. The 1/8" NPT female connections allow easy integration with compatible pipework.

Q: What types of media can be measured with this pressure gauge?

A: This device is specifically engineered to measure low-pressure differentials of air or other non-corrosive, compatible gases. It should not be used with liquids or corrosive gases to ensure measurement integrity and product longevity.

Q: When should I use the zero adjustment screw on the gauge?

A: Use the external zero adjustment screw to recalibrate the pointer to zero before taking measurements, especially after installation, maintenance, or if the gauge has experienced any impact or temperature fluctuations. This ensures continued accurate readings.

Q: Where is the Magnehelic Differential Pressure Gauge commonly applied?

A: It finds frequent use in industrial and commercial environments, particularly for monitoring HVAC filter conditions, detecting leakages, and indicating fan or blower pressure. Its general-purpose enclosure makes it suitable for typical indoor facility settings, but not for hazardous locations.

Q: What are the main benefits of the Dwyer 2203 Magnehelic Gauge for industrial users?

A: Key advantages include immediate mechanical response, high accuracy (2% full scale), robust construction, clear analog display, and easy recalibration. Its versatility and industrial-grade design make it a reliable choice for continuous pressure monitoring applications.

Q: How quick is the response time of this gauge during pressure changes?

A: The Magnehelic gauge features immediate, real-time mechanical analog response, providing instant visual feedback when pressure differentials occur, which is crucial for real-time system monitoring and maintenance.
