About Dwyer 2000-125PA Magnehelic Differential Pressure Gauge

Dwyer 2000-125PA Magnehelic Differential Pressure Gauge

Dwyer 2000-125PA MAGNEHELIC, DIFFERENTIAL PRESSURE GAUGE, 0/125PA, VS

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.

What's included with the Dwyer 2000-125PA

Dwyer 2000-125PA Magnehelic Differential Pressure Gauge (0-125 Pa), Vertical Scale

Robust Construction and Design

Built with a die-cast aluminum case and finished with a durable black powder coating, the Dwyer 2000-125PA Magnehelic Gauge combines resilience and longevity. Its acrylic cover and silicone rubber seals further enhance reliability, while the precision-engineered dial and pointer ensure accurate visual readings for every application.

Precise and Versatile Measurement

Offering a fine 1 Pa resolution and a 0125 Pa scale range, this instrument achieves 2% accuracy of the full scale. Its diaphragm sensor accommodates a variety of industrial applications, such as clean room pressure management, filter monitoring, and fan or blower pressure checks, catering to both critical and routine needs.

Easy Installation and Operation

The gauge supports both surface and flush mounting on vertical panels and includes the necessary adapters, screws, and NPT fittings in the kit. Clear analog display, straightforward external zero adjustment, and compatibility with standard 1/8 NPT threads facilitate smooth setup and regular operation by engineers and facility managers.

FAQs of Dwyer 2000-125PA Magnehelic Differential Pressure Gauge:

Q: How do I install the Dwyer 2000-125PA Magnehelic Differential Pressure Gauge?

A: To install, mount the gauge vertically using either the surface or flush mounting adapters provided. Connect the input ports to your systems pressure source via the 1/8 NPT side fittings. Ensure all connections are secure and use the supplied accessories for proper setup.

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

A: The Dwyer 2000-125PA is designed for measuring air and non-corrosive gases only. It is not suitable for aggressive chemicals or corrosive media, as these could damage the internal components and seals.

Q: When should I use the external zero adjustment screw?

A: Use the external zero adjustment screw to recalibrate the gauge when the pointer is not resting at zero with equalized pressures, or before each use to ensure optimal accuracy, especially if the gauge has experienced handling or vibration.

Q: Where can this differential pressure gauge be applied?

A: This model is ideal for filter monitoring, monitoring static pressure in ducts, clean room pressure management, and measuring blower or fan pressure, primarily in industrial settings such as HVAC systems, pharmaceutical labs, and manufacturing environments.

Q: What is the process for reading pressure values on the gauge?

A: Once installed and connected, the red acrylic pointer will move in response to pressure differential. Read the value at the place where the pointer aligns with the white aluminum dial scale, which has clear markings from 0 to 125 Pa.

Q: What are the benefits of using this gauge in my application?

A: The Dwyer 2000-125PA offers precise and reliable pressure measurement with excellent build quality, ease of installation, and low maintenance. Its durable materials and clear analog display provide long-term value and accurate monitoring for critical systems.
