About Dwyer 2000-300CM Magnehelic Differential Pressure Gauge

Dwyer 2000-300CM Magnehelic Differential Pressure Gauge

Model: 2000 Differential Pressure Gage, Range 0-300 CM W.C., Minor Divisions 10.0.

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

Dwyer 2000 MAGNEHELIC DIFFERENTIAL PRESSURE GAUGE 0-300 CM

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 over pressures.

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 Application and Mounting Options

This gauge features universal mounting possibilities, including standard vertical surface and flush mount, to fit diverse installation needs. With side or optional rear connections and included accessories, setup is straightforward. The gauge supports both instantaneous response and clear monitoring, making it ideal for both standard and specialized air handling systems.

FAQ's of Dwyer 2000-300CM Magnehelic Differential Pressure Gauge:

Q: How is the Dwyer 2000-300CM Magnehelic Gauge used in HVAC applications?

A: The Dwyer 2000-300CM is primarily used in HVAC systems to monitor air filter condition, detect duct pressure drops, and maintain clean room standards by measuring differential air pressure. By providing real-time, accurate readings, it helps ensure system efficiency and alerts operators to potential issues like clogged filters.

Q: What is the recommended process for zero adjustment on this gauge?

A: Zero adjustment is performed externally using the zero adjustment screw provided on the gauge's face. Before pressurizing the system, ensure the gauge is mounted vertically and the pressures are equalized. Then, rotate the screw until the pointer aligns with zero on the dial for optimal accuracy.

Q: Where can the gauge be mounted, and will mounting orientation affect performance?

A: The gauge is designed for vertical mounting as standard. It can be surface or flush mounted using included screws. Mounting the gauge in any orientation other than vertical can affect the accuracy of readings, so it is recommended to keep it level during installation.

Q: What type of media can this gauge measure pressure for?

A: This gauge is suitable for measuring the pressure of air and non-corrosive gases only. The die-cast aluminum case, silicone rubber seals, and acrylic cover are not compatible with corrosive or liquid substances.

Q: When should the gauge be checked for accuracy and recalibrated?

A: Regular accuracy checks and recalibration should be performed at intervals specified by your maintenance schedule, particularly in critical applications like clean rooms or HVAC filter monitoring. Periodic zero adjustments will help maintain measurement accuracy over time.

Q: What benefits does the instantaneous response feature provide?

A: The instantaneous response allows users to see real-time pressure changes, making it easier to detect sudden fluctuations, promptly troubleshoot system anomalies, and maintain optimal environmental control.

Q: Which accessories are included with the gauge for installation?

A: Each gauge comes with two 1/8 NPT plugs, two mounting screws, and an instruction sheet, providing everything needed for straightforward installation and setup.
