About Dwyer 2004D Magnehelic Differential Pressure Gauge

Dwyer 2004D Magnehelic Differential Pressure Gauge

Select the Magnehelic gage for high accuracy--guaranteed within 2% of full scale--and for the wide choice of 81 models available to suit your needs precisely. Using Dwyer's simple, frictionless Magnehelic gage movement, it quickly indicates low air or non-corrosive gas pressures--either positive, negative (vacuum) or differential. The design resists shock, vibration and over-pressures. No manometer fluid to evaporate, freeze or cause toxic or leveling problems. It's inexpensive, too. The Magnehelic gage is the industry standard to measure fan and blower pressures, filter resistance, air velocity, furnace draft, pressure drop across orifice plates, liquid levels with bubbler systems and pressures in fluid amplifier or fluidic systems. It also checks gas-air ratio controls and automatic valves, and monitors blood and respiratory pressures in medical care equipment.

Product Highlights

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

Overpressure Protection

Blowout plug is comprised of a rubber plug on the rear which functions as a relief valve by unseating and venting the gage interior when over pressure reaches approximately 25 PSIg (1.7 bar). To provide a free path for pressure relief, there are four spacer pads which maintain 0.023" clearance when gage is surface mounted. Do not obstruct the gap created by these pads. The blowout plug is not used on models above 180" of water pressure, medium or high pressure models, or on gages which require an elastomer other than silicone for the diaphragm. The blowout plug should not be used as a system overpressure control. High supply pressures may still cause the gage to fail due to over pressurization, resulting in property damage or serious injury. Good engineering practices should be utilized to prevent your system from exceeding the ratings or any component.

O-ring seal for cover assures pressure integrity of case. Samarium Cobalt magnet mounted at one end of range spring rotates helix without mechanical linkages.

Precise Differential Pressure Measurement

Designed for critical environments such as HVAC systems, clean rooms, and process applications, the Dwyer 2004D Magnehelic Gauge offers accurate and immediate differential pressure readings. Its diaphragm sensor type ensures reliable measurements of air and non-corrosive gases, supporting applications where sensitive pressure monitoring is essential.

Built for Industrial Demands

Manufactured with a robust die-cast aluminum case and sealed with durable silicone rubber, the gauge is engineered to withstand harsh environments. Its clear acrylic lens and precision-molded parts ensure clarity and long-term calibration stability, while the IP52 enclosure rating guarantees protection against dust and limited water ingress.

Flexible Installation and Easy Maintenance

The Dwyer 2004D can be mounted on any flat surface or panel using the included bracket and mounting accessories. With external screw zero adjustment, a calibration screw, and user-friendly design, regular maintenance and recalibration are straightforward, ensuring optimal performance with minimal downtime.

FAQs of Dwyer 2004D Magnehelic Differential Pressure Gauge:

Q: How do I connect the Dwyer 2004D Magnehelic Gauge to my application?

A: The gauge features two 1/8" NPT female ports (high and low) for pressure connections. Attach tubing from the monitored locationsone to the high port and the other to the low portusing compatible fittings, ensuring airtight seals for accurate measurement.

Q: What types of media can the Dwyer 2004D Magnehelic Differential Pressure Gauge measure?

A: This gauge is designed specifically for measuring differential pressures of air and non-corrosive gases. It is not suitable for liquids or corrosive gas applications due to its mechanical diaphragm and material construction.

Q: When is recalibration of the Dwyer 2004D necessary, and how is it performed?

A: Periodic recalibration is recommended based on usage frequency and regulatory requirements. Zero adjustment and recalibration can be carried out using the external screw and calibration screw, following guidelines provided in the instruction manual.

Q: Where can the Dwyer 2004D be installed?

A: This model is suitable for both surface and flush mounting, making it versatile for control panels, HVAC ducting, clean rooms, and process control stations. The supplied mounting bracket and accessories enable secure, easy installation.

Q: What is the benefit of using a mechanical diaphragm sensor in the Dwyer 2004D?

A: A mechanical diaphragm sensor delivers immediate response without electronic lag, ensuring precise analog readings. This design is reliable, resistant to vibration, and effective in demanding industrial environments.

Q: How accurate is the Dwyer 2004D, and what is its display range?

A: The gauge offers an accuracy of 2% of full scale, with a measurement range of 04 inch water column (w.c.), making it ideal for monitoring subtle pressure variations in sensitive applications.
