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 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.

Precise Differential Pressure Measurement

The Dwyer 2000-250CM Magnehelic Gauge is tailored for accurate detection of air and non-corrosive gas pressure differences. With diaphragm actuation and a scale range up to 250 mmWC, it offers reliable readings for critical applications such as HVAC filter monitoring and clean room pressure management, ensuring optimal system performance and safety.

Durable and Versatile Construction

This gauge is built with a die-cast aluminum body, acrylic cover, and a powder-coated/painted finish for durability. The device is suited for industrial environments, and its dual mounting configurationsurface or flushprovides flexibility for installation in a variety of system setups. Duplicate taps on both back and side further enhance its adaptability.

User-Friendly Operation and Compliance

Equipped with an analog display, clear dial markings, and supplied mounting accessories, the 2000-250CM is easy to install and use. Immediate mechanical response ensures accurate real-time monitoring. Its also RoHS compliant, meeting environmental and industrial standards for safe usage in India and beyond.

FAQs of Dwyer 2000-250CM Magnehelic Differential Pressure Gauge:

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

A: The gauge can be mounted either on the surface or flush with your control panel. Use the supplied mounting hardware and adapters. Connect the high and low pressure taps (1/8 NPT female) to compatible tubing or pipes using the included adapters for a secure fit.

Q: What types of media can be measured with this gauge?

A: The 2000-250CM is designed for air and non-corrosive gases only. Using this gauge with corrosive substances or liquids may damage the internal components and affect measurement accuracy.

Q: When should I use the Magnehelic Differential Pressure Gauge?

A: This gauge is ideal for situations requiring precise air or gas pressure measurement, such as monitoring air filter performance, measuring fan or blower pressure, maintaining clean room conditions, and monitoring duct static pressure.

Q: Where is the best place to mount this gauge in a system?

A: Mount the gauge in a location that enables easy access to both high and low pressure ports close to the area where pressure differential needs to be measured, such as across filters or in ductwork.

Q: What is the overpressure limit for the Dwyer 2000-250CM?

A: The gauge is designed to withstand pressures only up to its rated range of 0-250 mmWC. It can tolerate brief momentary overpressure, but continuous or severe overpressure must be avoided to prevent damage.

Q: How does the Magnehelic gauge provide instant readings?

A: The mechanical diaphragm-actuated design ensures an immediate response to pressure changes, allowing users to monitor variations in real time without electronic delays.

Q: What are the primary benefits of using this industrial-grade gauge?

A: Key benefits include high measurement accuracy (2% full scale), immediate mechanical response, versatile mounting, robust construction, RoHS compliance, and suitability for a range of industrial monitoring applications in Indian markets.
