Review DWYER Magnehelic Differential Pressure Gauge 0-40 Inch W.c

The Dwyer Model 2040 Magnehelic Differential Pressure Gauge is an essential instrument for measuring and monitoring pressure differences in various industrial applications. This durable and versatile gauge is designed to provide accurate and reliable readings within the range of 0 to 40 inches of water column (w.c).

The Magnehelic technology used in this gauge offers several advantages over traditional pressure gauges. The flexible, corrugated tube design provides a large, easy-to-read dial face with a graduated scale that indicates both the pressure difference and the absolute pressure. The tube also acts as a differential pressure element, eliminating the need for separate pressure transmitters or gauges, making it a cost-effective and streamlined solution.

The gauge housing is constructed of heavy-duty, die-cast aluminum, ensuring durability and resistance to corrosion and harsh environments. The dial face is protected by a scratch-resistant, impact-resistant, and shatter-proof glass lens. The gauge comes with a factory-installed 1/8 NPT thread connection, but other connection options are available upon request.

The 2040 Magnehelic Differential Pressure Gauge features a high-contrast, easy-to-read dial face with a red pointer, making it simple to track pressure differences even in low-light conditions. The gauge is also easy to install and calibrate, requiring no external power source and minimal maintenance.

The accuracy of the gauge is traceable to National Institute of Standards and Technology (NIST) standards, ensuring consistent and dependable readings in various applications. The gauge is suitable for use in a wide range of industries, including HVAC, process control, and water treatment, among others.

In summary, the Dwyer Model 2040 Magnehelic Differential Pressure Gauge is a reliable, accurate, and versatile instrument for measuring and monitoring pressure differences in industrial applications. Its rugged construction, ease of use, and wide range of applications make it an indispensable tool for professionals in various industries.

A Detailed Analysis of the Dwyer Model 2040 Magnehelic Differential Pressure Gauge (0-40 w.c)

The Dwyer Model 2040 Magnehelic Differential Pressure Gauge is a popular choice for measuring the pressure difference between two points in a liquid or gas system. In this analysis, we will discuss the key features, advantages, and disadvantages of this gauge.

1. Magnetic drive design for accurate and reliable measurement

2. Wetted parts are constructed from 316L stainless steel for corrosion resistance

3. Operating pressure range: 0-40 w.c (water column)

4. Accuracy: 1.5% of full scale (FS)

5. Temperature range: -20 F to 250 F (-28.9 C to 121.1 C)

6. Easy-to-read dial with a broad viewing angle

7. Compact design for easy installation

1. Magnetic drive design eliminates the need for internal seals, reducing the chances of leaks and maintenance requirements.

2. 316L stainless steel construction ensures durability and corrosion resistance in harsh environments.

3. Wide temperature range makes it suitable for a variety of applications.

4. Easy-to-read dial with a broad viewing angle allows for quick and accurate pressure measurements.

5. Compact design facilitates installation in confined spaces.

1. Limited operating pressure range may not be suitable for high-pressure applications.

2. Relatively higher cost compared to other differential pressure gauges with similar features.

The Dwyer Model 2040 Magnehelic Differential Pressure Gauge is an excellent choice for applications requiring accurate and reliable pressure difference measurements in a wide temperature range. Its magnetic drive design and corrosion-resistant construction make it suitable for use in harsh environments. However, its limited operating pressure range and relatively higher cost may be disadvantages for some users.

If you require a differential pressure gauge with a higher operating pressure range or a lower cost, consider evaluating other models in the Magnehelic or other pressure gauge series from Dwyer Instruments or other manufacturers. However, if the features and advantages of the Dwyer Model 2040 align with your application requirements, it is an excellent investment for precise and reliable pressure difference measurements.

Details:

It is locked and sealed in position with a sealing plate retaining ring. O-ring seal for cover assures pressure integrity of case. O-ring seal provides pressure tightness. Provides un distorted viewing of pointer and scale.

It is rigidly mounted on the helix shaft. Diaphragm motion is restricted to prevent damage due over pressures. Red tipped pointer of heat treated aluminum tubing is easy to see. Untitled Document, Dwyer 2040 Magnehelic Differential Pressure Gauge 0-40 w.c.: model: Order No:2040: Bezel provides flange for flush mounting in panel.

Shipping: We currently only ship to USA buyers. Die cast aluminum case is precision made and erudite-dipped to withstand 168 hour salt spray corrosion test. Mounted in jeweled bearings, it turns freely, following the magnetic field to move pointer across scale. Helix is precision made from an alloy of high magnetic permeability.

It reacts to pressure on diaphragm. May be used with hydrogen. Exterior finished in baked dark gray hammerlock. Samarium Cobalt magnet mounted at one end of range spring rotates helix without mechanical linkages.

Pointer stops of molded rubber prevent pointer over-travel without damage. Dwyer 2040 Magnehelic Differential Pressure Gauge 0-40 w.c.: MAGNEHELIC, PRESSURE GAUGE, 0/40: Precision lithe-printed scale is accurate and easy to read. Motion damped with high viscosity silicone fluid. Clear plastic face is highly resistant to breakage.

Small amplitude of motion assures consistency and long life. Jeweled bearings are shock-resistant mounted; provide virtually friction-free motion for helix. Silicone rubber diaphragm with integrally molded O-ring is supported by front and rear plates. Wishbone assembly provides mounting for helix, helix bearings and pointer shaft.

Brand: Dwyer, model: 2040, Order No: condition: NEW. Calibrated range spring is flat steel. One case size is used for all standard pressure options, and both surface flush mounting. Live length adjustable for calibration.
