Dwyer 2215 MAGNEHELIC, DIFFERENTIAL PRESSURE GAUGE, 0-15 PSI

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.

Engineered for Industrial Reliability

With its durable die-cast aluminum construction and acrylic dial cover, the Dwyer 2215 is built to withstand demanding environments and frequent usage. The device meets NEMA Type 1 enclosure standards, ensuring excellent protection in industrial settings. Extensive calibration and field adjustability facilitate accurate readings and long-term performance.

Clear and Immediate Pressure Indication

The analog display provides immediate mechanical feedback for differential pressure readings, making it ideal for quick glance monitoring. Its full-view, clear acrylic window and precisely balanced aluminum pointer enhance visibility and reading accuracy even from a distance.

FAQs of Dwyer 2215 Magnehelic Differential Pressure Gauge 0-15 PSI:

Q: How is the Dwyer 2215 Magnehelic Differential Pressure Gauge installed?

A: The gauge can be mounted on a surface or flush-mounted using the supplied mounting screws. Side process connections (1/8 NPT threads) allow for easy hookup to air or non-combustible gas lines as required in your application.

Q: What applications can the Dwyer 2215 Magnehelic Gauge be used for?

A: This gauge is commonly used for monitoring filter status, measuring duct static pressure, fan and blower pressures, and assessing air velocity in HVAC and industrial systems. It measures the differential pressure of air and other non-combustible gases.

Q: When should I perform zero or field adjustment on this gauge?

A: Zero adjustment is recommended whenever recalibration is necessary, such as following installation, routine maintenance, or if the gauge has experienced any significant mechanical impact. Use the external adjustment screw for convenient calibration without disassembling the unit.

Q: Where can the Dwyer 2215 be used safely?

A: Thanks to its NEMA Type 1 enclosure and robust construction, the gauge is suitable for indoor industrial environments, such as HVAC control panels, air handling units, and cleanroom monitoring stations. Avoid installing it outdoors or in environments containing combustible gases.

Q: What is the process to read and interpret the gauge display?

A: Simply observe the analog display through the full-view acrylic window. The balanced aluminum pointer and clear scale provide an immediate, easy-to-read indication of differential pressure between two points in your system.

Q: What are the main benefits of using the Dwyer 2215 Magnehelic Gauge?

A: The gauge delivers quick, accurate, and reliable pressure readings, making system monitoring straightforward. Its rugged industrial design and field adjustability reduce maintenance downtime and support long-term dependability.
