About Dwyer 2202 Magnehelic Differential Pressure Gauge 0-2 PSI

Dwyer 2202 Magnehelic Differential Pressure Gauge 0-2 PSI

Model: 2202 -Differential Pressure Gage, Range 0-2 PSI, Minor Divisions .05.

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

Dwyer 2202 MAGNEHELIC, DIFFERENTIAL PRESSURE GAUGE, 0-2 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 Pressure Monitoring

Ensure your industrial systems are operating efficiently with the Dwyer 2202 Magnehelic Differential Pressure Gauge. Its high-accuracy analog display and durable construction make it ideal for monitoring filter conditions, fan performance, and duct pressures, helping to prevent system failures and minimize maintenance costs.

Built for Tough Environments

Engineered with a die-cast aluminum case, the gauge is IP54-rated to resist dust and splashes, making it suitable for challenging industrial conditions. The diaphragm-actuated sensor and silicone rubber seals provide reliable readings even in variable temperatures ranging from -7C to 60C.

Easy Installation and Versatility

Surface or flush mounting options, included accessories, and standard 1/8" NPT female connections offer hassle-free installation into new or existing setups. The external zero adjustment screw lets users calibrate on-site, ensuring ongoing accuracy with minimal downtime.

FAQs of Dwyer 2202 Magnehelic Differential Pressure Gauge 0-2 PSI:

Q: How do I install the Dwyer 2202 Magnehelic Differential Pressure Gauge?

A: Installation is straightforward using the provided mounting screws, rubber process connectors, and panel mount adapter. The gauge can be surface or flush mounted, with high and low pressure connections made via the 1/8" NPT female threads. Detailed instructions are included for both vertical and horizontal placements.

Q: What are the key applications for this pressure gauge?

A: Common uses include filter monitoring, fan pressure indication, duct static pressure measurement, and any application requiring low differential pressure measurement of air or compatible gases in industrial environments.

Q: When should I perform zero adjustment on the gauge?

A: Zero adjustment should be performed during installation or if you notice a drift from zero when both pressure ports are open to atmospheric pressure. The external screw type adjustment makes it easy to recalibrate without disassembling the unit.

Q: Where can this gauge be used safely?

A: It can be safely used in environments with an operating temperature between -7C and 60C (20F to 140F). The IP54 rating offers protection from dust and slow splashes, making it suitable for most industrial indoor applications.

Q: What is the benefit of the diaphragm actuated sensor in this gauge?

A: The diaphragm actuated sensor provides reliable and accurate measurements with a quick response time, ensuring that even small pressure changes are detected promptly. This enhances process control and equipment safety.

Q: How do I ensure accurate readings over time?

A: Regularly check zero calibration and use the external adjustment screw as needed. Avoid exposure to pressure above 15 PSI, and keep the gauge clean and free from dust for optimal performance.
