About Dwyer 2000-80CM Magnehelic Differential Pressure Gauge

Dwyer 2000-80CM Magnehelic Differential Pressure Gauge

Model: 2000 Differential Pressure Gage, Range 0-80 CM W.C., Minor Divisions 2.0.

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 0-80 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 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 Measurement

The Dwyer 2000-80CM Magnehelic Gauge provides highly accurate monitoring of differential pressure, suitable for air and non-corrosive gases in demanding industrial environments. Its analog display with a clear acrylic window ensures quick visual checks, while immediate response time enables prompt readings for critical applications.

Built for Industrial Environments

Engineered for resilience, this gauge features a die-cast aluminum case with a matte or polished finish, silicone rubber seals, and an IP54-equivalent enclosure rating. These dimensions shield the device from dust and splashes, prolonging its lifespan and maintaining accuracy even in challenging conditions.

Flexible Installation and User-Friendly Features

With both rear or side 1/8 NPT threading and accessory mounting hardware included, this Magnehelic gauge supports surface or panel mounting. Vertical orientation is recommended for best precision, and an external screw allows straightforward zero calibration to ensure optimal performance throughout its service life.

FAQ's of Dwyer 2000-80CM Magnehelic Differential Pressure Gauge:

Q: How should the Dwyer 2000-80CM Magnehelic Differential Pressure Gauge be installed for optimal accuracy?

A: For the best measurement accuracy, install the gauge in a vertical position using the provided mounting screws, ensuring it is flush or panel-mounted as required. Both rear and side 1/8 NPT connections are available for flexible installation.

Q: What type of substances can this pressure gauge measure?

A: The 2000-80CM is designed to measure the differential pressure of air and other non-corrosive gases only. Using it with corrosive gases or liquids could damage internal components and compromise accuracy.

Q: When is zero adjustment necessary, and how is it performed?

A: Zero adjustment is typically needed during initial setup or periodically as part of routine maintenance. The gauge features an external screw, allowing you to easily calibrate the pointer back to zero when no differential pressure is present.

Q: Where can the Dwyer Magnehelic Gauge be used?

A: This gauge is ideal for industrial environments such as HVAC systems, cleanrooms, filter monitoring, and other facilities requiring precise air or gas pressure measurements. Its IP54-rated enclosure provides protection in dusty or moist conditions.

Q: What are the included accessories, and how do they assist the installation process?

A: The Dwyer 2000-80CM comes with two mounting screws, plastic static pressure tips, and durable rubber tubing. These accessories facilitate secure installation and ensure accurate, stable connections to the pressure sources.

Q: How does the immediate response time benefit industrial applications?

A: The immediate mechanical response enables operators to instantly monitor pressure changes, helping to promptly address fluctuations or potential system issues, which is critical in maintaining process stability and safety.

Q: What maintenance is required to keep this gauge functioning accurately?

A: Periodic zero adjustment, ensuring a clean lens, and confirming fitting tightness are usually sufficient. Regular inspections for leaks or damage to seals and tubing will help maintain long-term accuracy and gauge reliability.
