About Dwyer 2300-3KPA Magnehelic Differential Pressure Gauge
Dwyer 2300-3KPA Magnehelic Differential Pressure Gauge
Dwyer 2300-3KPA MAGNEHELIC, DIFFERENTIAL PRESSURE GAUGE, 1.5-0-1.5
- 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.

Accurate Differential Pressure MeasurementThe Dwyer 2300-3KPA Magnehelic Gauge is designed to deliver precise monitoring of low differential pressures in air and non-combustible gas systems. Its analog display enables clear, quick readings, and the 2% full-scale accuracy ensures dependable results in demanding industrial environments.
Robust Construction for Industrial UseBuilt with a die-cast aluminum housing and acrylic cover, this gauge withstands tough conditions. It is rated for 15 psi (103 kPa) overpressure and offers a vertical mounting style, making it suitable for various applications including HVAC, filter monitoring, and cleanroom control.
Convenient Installation and MaintenanceMounting is straightforward with surface or flush options as well as supplied brackets and adapters. The IP52-rated enclosure resists dust and moisture ingress, and the external zero adjustment screw provides effortless recalibration, supporting ongoing accuracy without disassembly.
FAQ's of Dwyer 2300-3KPA Magnehelic Differential Pressure Gauge:
Q: How do I install the Dwyer 2300-3KPA Magnehelic Differential Pressure Gauge?
A: The gauge is designed for vertical mounting and can be installed using the included brackets and screw pack. It features 1/8" NPT female connections and comes with pipe thread adapters for compatibility with standard fittings. Both surface and flush mounting options are supported to suit your application.
Q: What types of media can this differential pressure gauge measure?
A: The Dwyer 2300-3KPA gauge is intended for use with air and non-combustible gases only. It is not suitable for measuring the pressure of liquids, aggressive gases, or combustible materials.
Q: When should I use the external zero adjustment screw?
A: You should use the external zero adjustment screw whenever you need to recalibrate the gauge to ensure precise readings. This is often required after installation, periodic maintenance, or if the pointer drifts from zero under no pressure conditions.
Q: Where can the Dwyer 2300-3KPA be installed for optimal performance?
A: The gauge is best installed in an environment with operating temperatures ranging from -7C to 60C and where it is shielded from excessive dust and moisture. The IP52 rating provides some protection, but installing away from water spray or heavy particulates will help maintain accuracy and longevity.
Q: What process does the gauge use to measure differential pressure?
A: This model utilizes a precision jeweled bearing movement and a diaphragm-based sensor to detect pressure differences between its two input ports. The analog dial then displays the measured differential pressure within the 0-3 kPa range.
Q: How does the industrial-grade construction benefit users?
A: The robust die-cast aluminum housing and clear acrylic cover provide durability, shock resistance, and long service life. These features make the gauge suitable for demanding environments where consistent, reliable performance is critical.
