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.

All necessary mounting accessories and instructions are provided for hassle-free setup.

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 flush or surface mounted using the supplied panel mounting adapters and screws. It is designed for vertical orientation as standard, and connections for high and low pressure are 1/8 NPT female threads.

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

A: This gauge is suitable for measuring air and non-corrosive gases only. It is not intended for use with liquids or corrosive gases due to the materials of construction.

Q: When should I use the Dwyer 2204 Magnehelic Gauge in my facility?

A: This gauge is ideal for monitoring differential pressure in HVAC systems, filter status, clean room pressure, fan and blower performance, and room pressurization. Use it whenever precise, immediate pressure readings are required.

Q: Where can the gauge be mounted for best accuracy?

A: For the most accurate readings, mount the gauge vertically as recommended by the manufacturer. Ensure it is installed in a location protected from water and excessive dust, consistent with its IP52 enclosure rating.

Q: What is the benefit of the external zero adjustment screw?

A: The external adjustment screw allows users to quickly and easily recalibrate the zero point of the gauge without disassembly, ensuring ongoing accuracy throughout its use.

Q: How fast is the response time of this gauge?

A: The Dwyer 2204 has an immediate response time, typically less than 1 second, providing real-time differential pressure readings for prompt monitoring and control.
