About Dwyer 2025D Magnehelic Differential Pressure Gauge

Dwyer 2025D Magnehelic Differential Pressure Gauge

Dwyer Instruments 2025D

Magnehelic Pressure Gauge 0-25 in H2O, 0-6.2 kPa

Dual scale. Bezel provides flange for flush mounting in panel. Clear plastic face is highly resistant to breakage. Provides undistorted viewing of pointer and scale.

Dwyer 2025D MAGNEHELIC, DIFFERENTIAL PRESSURE GAUGE, 0 - 25, 0-6.2 KPA

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

Engineered for critical monitoring, the Dwyer 2025D Magnehelic Gauge enables real-time differential pressure measurement in environments such as HVAC, process industries, and laboratories. Its robust die cast aluminum housing shields internal components from harsh conditions, while the polycarbonate window resists impact for long-term clarity and safety.

Versatile Mounting and Accessory Package

Installation is straightforward with options for surface or flush mounting. Accessories provided-such as NPT plugs, rubber tubing adapters, and mounting adapters with screws-streamline setup. The gauge suits both standard vertical and optional horizontal mounting, fitting seamlessly into diverse industrial configurations.

High Accuracy and Immediate Response

With a finely graduated analog dial offering 1 Pa resolution and 2% of full scale accuracy, the Magnehelic ensures precise control of critical processes. Its mechanical, diaphragm-actuated sensor delivers immediate feedback, allowing users to react swiftly to pressure fluctuations.

FAQ's of Dwyer 2025D Magnehelic Differential Pressure Gauge:

Q: How do I install the Dwyer 2025D Magnehelic Differential Pressure Gauge?

A: The gauge can be surface or flush mounted, using the included mounting adapters and screws. Make sure to connect the two 1/8" NPT female high and low pressure ports as per your application, ensuring the unit is vertically oriented for standard operation or horizontally if required.

Q: What types of media can the 2025D Magnehelic Gauge measure?

A: This gauge is engineered to measure differential pressures of steam, oil, and gas. Its sensor and materials are suitable for these non-corrosive fluids commonly used in industrial settings.

Q: When is it recommended to use the Dwyer 2025D gauge?

A: It is best used whenever accurate, immediate, and reliable measurement of low differential pressures (up to 500 Pa) is crucial-such as in monitoring filters, air flow, or clean room pressures in industrial, HVAC, or laboratory environments.

Q: Where should the Magnehelic 2025D be mounted for optimal performance?

A: For optimal accuracy, mount the gauge vertically as standard. However, horizontal mounting is optional if necessary for your setup, ensuring correct calibration for the chosen orientation.

Q: What benefits does the shatterproof polycarbonate window offer?

A: The polycarbonate window is impact-resistant and protects the display from damage, ensuring clarity over time and maintaining safety in industrial environments.

Q: How fast does the gauge respond to pressure changes?

A: As a mechanical gauge, the 2025D delivers immediate response to any fluctuation in pressure, allowing users to monitor system changes in real time.

Q: What accessories are included with the Dwyer 2025D Magnehelic Gauge?

A: Delivered ready for installation, the package includes two 1/8 NPT plugs, two 1/8 NPT pipe thread to rubber tubing adapters, and three mounting adapters with screws for seamless setup.
