About Dwyer 2300-2.5KPA Magnehelic Differential Pressure Gauge
Dwyer 2300-2.5KPA Magnehelic Differential Pressure Gauge
Dwyer 2300-2.5KPA MAGNEHELIC, DIFFERENTIAL PRESSURE GAUGE, 1.25-0-1.25 kPa
- 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 2300-2.5KPA Magnehelic Differential Pressure Gauge:
Q: How is the Dwyer 2300-2.5KPA Magnehelic Differential Pressure Gauge installed?
A: The gauge is typically mounted vertically, using either surface or flush mount techniques. It features 1/8" NPT female connections on the side and back. All necessary accessories, such as static pressure tips, plugs, and mounting screws, are included to facilitate straightforward installation.
Q: What types of media can this gauge measure?
A: The Dwyer 2300-2.5KPA is suitable for monitoring the differential pressure of air and other compatible gases. It is not designed for use with liquids, corrosive gases, or hazardous media outside its specified compatibility.
Q: When is it necessary to adjust the zero point on the gauge?
A: Zero adjustment should be checked prior to initial operation or after relocation. The external adjustment screw allows quick calibration to ensure the pointer correctly reflects zero differential when both ports are open to atmospheric pressure, maintaining measurement accuracy.
Q: Where can this pressure gauge be effectively used?
A: It excels in industrial grade applications such as monitoring filter conditions, verifying duct or room pressures, assessing air velocity, and overseeing fan and blower outputs. Its robust construction and IP50 rating make it suitable for laboratories, cleanrooms, HVAC systems, and industrial plants.
Q: What maintenance process is recommended for optimal performance?
A: Routine maintenance involves periodic zero adjustment, checking for leaks or blockages in the pressure lines, and ensuring the polycarbonate window and dial remain clean for easy readability. Avoid applying excess overpressure as it may damage the sensing element.
Q: What are the key benefits of using this Magnehelic gauge over digital alternatives?
A: Its purely mechanical response delivers real-time pressure indication with immediate feedback, does not require power, and is less susceptible to electronic interference. The instruments durability and dependable accuracy make it ideal for continuous, long-term industrial monitoring.
