Dwyer Magnehelic Differential Pressure Gauge Model 2000-20KPA

Dwyer 2000-20KPA MAGNEHELIC, DIFFERENTIAL PRESSURE GAUGE, 0/20KPA

• 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.

Reliable Pressure Monitoring for Critical Environments

Ideal for HVAC, clean room, and filter monitoring applications, the Dwyer Magnehelic Model 2000-20KPA ensures precise differential pressure readings. Its injection-molded housing and die-cast aluminum build guarantee durability in industrial settings, while its clearly marked dial allows for easy monitoring, boosting workplace safety and compliance. Mounting flexibility gives users seamless integration in diverse environments.


Effortless Installation and Adjustment

This model is equipped with side and back pressure taps, accommodating standard 1/8 NPT female threads. An external adjustment screw provides simple zero calibration without disassembly. The package includes two mounting brackets, screws, and an instruction manual, allowing for quick, straightforward installation whether flush or surface mounting is preferred.


Performance and Safety Built In

Engineered for reliability, the 2000-20KPA model operates safely with a maximum working pressure of 100 kPa and resists overpressure up to 103 kPa. Its core diaphragm sensor delivers rapid, accurate readings, with an IP52-protected front face to withstand routine industrial environments. The silicone rubber seal ensures leak-free performance when measuring air or compatible gases.
