About Dwyer 2000-250CM Magnehelic Differential Pressure Gauge

Dwyer 2000-250CM Magnehelic Differential Pressure Gauge

Model: 2000 Differential Pressure Gage, Range 0-250 CM W.C., Minor Divisions 5.0.

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 0-250 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.

Precision Monitoring for Industrial Applications

Engineered for demanding industrial scenarios, the Dwyer 2000-250CM Magnehelic Differential Pressure Gauge delivers consistent monitoring for a variety of fluids, including steam, oil, and gas. Its diaphragm sensor and analog display ensure straightforward readings, while robust construction and overpressure safety features make it suitable for rigorous use.

User-Friendly Installation and Adaptability

The gauge's dual port configuration and versatile mounting options allow for easy integration into new or existing systems. Its external zero adjustment screw facilitates in-situ recalibration, while the package includes all necessary hardware for installation. Clear, durable acrylic cover ensures visibility of readings even in harsh conditions.

FAQ's of Dwyer 2000-250CM Magnehelic Differential Pressure Gauge:

Q: How do I install the Dwyer 2000-250CM Magnehelic Differential Pressure Gauge?

A: The gauge can be mounted vertically using the included pipe mounting brackets and screws. Dual ports on the side and back enable flexible connection to your pressure sources. Detailed instructions are provided in the package to assist with both surface and flush mounting options.

Q: What types of media can this differential pressure gauge measure?

A: This model is suitable for measuring the differential pressure of steam, oil, and gas, making it ideal for a broad range of industrial applications.

Q: When should I use the external zero adjustment screw?

A: The external zero adjustment screw allows you to re-calibrate the gauge when you notice deviations in baseline pressure readings, ensuring continued accuracy without disassembly.

Q: Where can this gauge be installed safely?

A: It is designed for vertical installation in environments where temperatures range between -7C and 60C. The robust housing and blowout plug offer safety against overpressure, while the die-cast aluminum case ensures durability in industrial settings.

Q: What process does the gauge use to measure differential pressure?

A: Utilizing a diaphragm sensor, the gauge measures the difference in pressure between two points (connected to its dual NPT ports), which is then displayed accurately on the analog dial.

Q: How does the overpressure protection feature benefit operation?

A: A blowout plug on the back of the gauge provides immediate relief in case of accidental overpressure, protecting internal components and enhancing operator safety.

Q: What are the main benefits of choosing this gauge for industrial use?

A: It offers precise differential pressure readings (2% accuracy), robustness against demanding conditions, dual port flexibility, straightforward maintenance, and clear analog display-key components for reliable monitoring in critical industrial applications.
