About Dwyer 2050D Magnehelic Differential Pressure Gauge

Dwyer 2050D Magnehelic Differential Pressure Gauge

Dwyer Instruments 2050D

Magnehelic Pressure Gauge 0-50 in H2O, 0-12.4 kPa

 

Dual scale. Bezel provides flange for flush mounting in panel. Clear plastic face is highly resistant to breakage. Provides undistorted viewing of pointer and scale.

 

Dwyer 2050D MAGNEHELIC, DIFFERENTIAL PRESSURE GAUGE, 0 - 50, 0-12.4 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.

Precision Measurement for Industrial Applications

The Dwyer 2050D Magnehelic gauge delivers precise and reliable differential pressure readings, minimizing errors with its 2% full-scale accuracy. Its durable diaphragm sensor ensures longevity and consistent performance under rigorous conditions. Designed for air and non-corrosive gases, this device is well suited for HVAC systems, clean rooms, and filter monitoring. Its sturdy construction and IP54-rated front cover enhance reliability even in dusty or humid environments.


Robust Build for Demanding Environments

With its powder-coated, die-cast aluminum casing and polycarbonate cover, the Dwyer 2050D excels in industrial settings. The vertical mount orientation and machined assembly enable secure, straightforward installation. The gauge remains unfazed by overpressures up to 15 psi (1.03 bar) and operates effortlessly between -7 to +60C, offering dependable operation in a variety of ambient conditions. Its gray finish and clear, easy-to-read dial complete this professional tool.
