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.

What's included with the Dwyer 2050D

Dwyer 2050D Magnehelic Differential Pressure Gauge (0-50"w.c. & 0-12.4 kPa)

Precision Engineered for Industrial Applications

Designed for measuring differential pressure in steam, oil, or gas systems, the Dwyer 2050D delivers reliable readings with a 2% full-scale accuracy. Its analog display and fine gradations offer precise, at-a-glance monitoring required in demanding industrial environments. The device features a robust die-cast aluminum case, a silicone rubber seal, and a clear acrylic lens for long-lasting use even in harsh conditions.


Versatile Mounting and Easy Installation

The gauge supports both surface and flush mounting orientations, with side-located connections for straightforward plumbing. It comes with two 1/8 NPT plugs, two mounting screws, and an instruction sheet, streamlining setup for new installations or replacements. The external adjustment screw allows for on-site zeroing, ensuring accurate calibration without disassembly.


Safety Features and Global Compliance

Select models are equipped with a relief valve to protect from overpressure surges, providing an added layer of safety for operators. The gauge meets international RoHS and CE standards upon request, appealing to exporters and manufacturers looking for compliant, world-class instruments. Its rugged construction and textured grey finish stand up to industrial demands.
