About Dwyer 2000-750PA Magnehelic Differential Pressure Gauge

Dwyer 2000-750PA Magnehelic Differential Pressure Gauge

Dwyer 2000-750PA MAGNEHELIC, DIFFERENTIAL PRESSURE GAUGE, 0/750PA

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.

Highly Accurate Differential Pressure Monitoring

Engineered for precision, the Dwyer 2000-750PA Magnehelic Differential Pressure Gauge provides 2% full-scale accuracy within a 0750 Pa range. Immediate response time and external zero adjustment allow for fine-tuned measurements and effortless recalibration. This makes it particularly suitable for maintaining optimal air and gas pressures in industrial processes and cleanroom environments.

Rugged Construction for Demanding Applications

Constructed from die-cast aluminum with a textured black finish and a mechanically gasketed design, this gauge stands up to tough industrial settings. Its IP55 ingress protection shields against dust and water jets, while an overpressure safety rating of 172 kPa (25 psi) assures operational durability. The 4-inch clear acrylic window ensures visibility and longevity.

FAQs of Dwyer 2000-750PA Magnehelic Differential Pressure Gauge:

Q: How do I install the Dwyer 2000-750PA Magnehelic Differential Pressure Gauge?

A: The gauge can be mounted either on the surface or flush using the supplied adapters and screws. Both back and bottom connection locations are available, and installation is straightforward with the included 1/8 NPT plugs, ensuring flexibility in various setups.

Q: What media can be measured with this pressure gauge?

A: This differential pressure gauge is specifically designed to measure air and non-corrosive gases, making it ideal for HVAC systems, filtration monitoring, and other similar applications.

Q: Where is the Dwyer 2000-750PA commonly used?

A: Typical applications include industrial settings such as cleanrooms, HVAC ducts, air handling units, and process control environments across manufacturing facilities in India.

Q: What are the benefits of the external zero adjustment screw?

A: The external zero adjustment screw allows for quick and simple recalibration without disassembly, ensuring ongoing measurement accuracy and saving time during maintenance.

Q: When does the gauge require recalibration and how is it done?

A: If you notice measurement drift or after extended use, recalibration can be performed using the external zero adjustment screw. This should be checked periodically as part of regular maintenance.

Q: What safety features does the gauge offer against overpressure?

A: The gauge can safely withstand accidental overpressure up to 172 kPa (25 psi) beyond its working range, ensuring protection against unforeseen pressure spikes.

Q: What is the process for maintaining the Magnehelic Gauge?

A: Maintenance involves periodically checking the gauge for leaks, ensuring connections are secure, cleaning the acrylic window for visibility, and using the external zero adjustment for recalibration as needed.
