About Dwyer 2000-500PA Magnehelic Differential Pressure Gauge

Dwyer 2000-500PA Magnehelic Differential Pressure Gauge

Dwyer 2000-500PA MAGNEHELIC, DIFFERENTIAL PRESSURE GAUGE, 0-500 PA

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.

FAQs of Dwyer 2000-500PA Magnehelic Differential Pressure Gauge:

Q: How do I install the Dwyer 2000-500PA Magnehelic Differential Pressure Gauge?

A: Installation is straightforwardmount the gauge vertically using the included flush or surface mounting accessories. Connect high and low-pressure lines via the 1/8" NPT ports, following the orientation guidelines to ensure accuracy. The gauge can be set up in HVAC ducts, cleanrooms, or any other compatible application.

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

A: This gauge is specifically designed to measure the differential pressure of air and non-corrosive gases. The use of proper media ensures accurate readings and maintains the longevity of the instrument.

Q: When should I perform zero adjustment on the Magnehelic Gauge?

A: Zero adjustment is recommended upon initial installation and periodically as part of routine maintenance. Use the external front adjustment screw while the pressure lines are open to atmospheric pressure for precise calibration.

Q: Where is this pressure gauge commonly used in industrial settings?

A: The Magnehelic Gauge is frequently used in cleanrooms, laboratories, filter monitoring stations, HVAC systems, and process industries across India. Its reliability and precision make it suitable for any environment requiring consistent differential pressure monitoring.

Q: What is the process for cleaning and maintaining the gauge?

A: Keep the lens and housing clean by gently wiping them with a soft, dry cloth. Avoid liquids or harsh chemicals. Periodically check the pressure connections for leaks or buildups. Make sure the device is within its specified temperature range and always protected from corrosive substances to ensure long-term accuracy.

Q: How does an analog needle gauge provide benefit over digital gauges in certain applications?

A: Analog needle gauges like the Dwyer Magnehelic offer instant, continuous visual readings without the need for power, making them ideal for quick assessments and environments where reliability and real-time visualization are crucial. Their mechanical simplicity also ensures lower maintenance needs.
