About Dwyer Magnehelic Differential Pressure Gauge Model 2000-30KPA

Dwyer Magnehelic Differential Pressure Gauge Model 2000-30KPA

Dwyer 2000-30KPA MAGNEHELIC, DIFFERENTIAL PRESSURE GAUGE, 0/30KPA

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.

Industrial-Grade Precision

Engineered for reliability, the Dwyer Magnehelic Differential Pressure Gauge Model 2000-30KPA features an industrial-grade diaphragm sensor that delivers immediate mechanical response with minimal hysteresis. Its robust design ensures consistent accuracy, making it optimal for challenging environments that require precise differential pressure monitoring.

Durable and Versatile Design

Built with a die-cast aluminum case and finished in corrosion-resistant baked enamel, this gauge is resilient under demanding industrial conditions. It comes equipped with all necessary accessories for surface or panel mounting, and its vertical orientation ensures optimal performance. The side port configuration and clear analog display enhance usability and installation flexibility.

FAQs of Dwyer Magnehelic Differential Pressure Gauge Model 2000-30KPA:

Q: How is the Dwyer Magnehelic Model 2000-30KPA installed and mounted?

A: This gauge is designed for vertical mounting, either on a surface or panel, using the included mounting screws. The side ports accommodate a 1/8 NPT female thread, making it straightforward to connect with the provided static pressure tips and plastic tubing.

Q: What type of media can be measured using this pressure gauge?

A: The Model 2000-30KPA is suitable for measuring differential air pressure and non-corrosive gases only. It is not designed for use with liquids or aggressive chemical gases.

Q: Where can the Magnehelic 2000-30KPA be effectively used?

A: This model is ideal for industrial applications in India where monitoring air or compatible gas pressures is critical, such as HVAC systems, filter monitoring, or clean room environments.

Q: What are the benefits of its diaphragm differential pressure sensor design?

A: The diaphragm sensor provides immediate mechanical response and ensures negligible hysteresis, resulting in highly accurate and repeatable pressure readings, even in fluctuating conditions.

Q: How is zero adjustment performed on the gauge?

A: Zero adjustment can be easily executed using the external adjustment screw located on the gauge front. This simplifies calibration and maintenance without the need for disassembly.

Q: When should the gauge not be used?

A: Avoid using this Magnehelic gauge with corrosive gases, liquids, or in orientations other than vertical, as these may compromise accuracy, response time, or damage internal components.

Q: What is included with the Dwyer Magnehelic Model 2000-30KPA purchase?

A: Alongside the pressure gauge, you receive two static pressure tips, three mounting screws, and a length of plastic tubing to facilitate convenient and secure installation.
