Product Description

Product Description

 Dwyer differential pressure gauges 

The Dwyer 2000 series Magnehelica differential pressure gauges operate based on the Magnehelic electromagnetic connection principle. This principle is centered around a simple and frictionless movement mechanism, which is crucial for its reliable performance. When there exists a pressure difference between the two measurement points, this pressure differential causes a diaphragm to deflect. The diaphragm, a key component in the pressure - sensing mechanism, is designed to be highly sensitive to even the slightest pressure variations.
As the diaphragm deflects, it initiates a chain of events. The deflection is then translated into the movement of a magnetic element. This magnetic element is strategically placed within the gauge and is designed to interact with a magnetically - coupled pointer on the scale. The interaction between the magnetic element and the pointer results in the pointer moving along the scale, thereby indicating the differential pressure value on the gauge. This design not only ensures accurate readings but also provides excellent vibration resistance. The frictionless movement of the components reduces wear and tear, contributing to the long - term stability and durability of the gauge. Over a long period of operation, the gauge can maintain its performance without significant degradation, making it suitable for continuous use in various industrial environments.

1. Product Features

1.1 Accuracy
Accuracy is a critical aspect of any differential pressure gauge, and the Dwyer 2000 series does not disappoint. The standard models of the 2000 series offer an accuracy of within 2% of full scale. This level of accuracy is sufficient for a wide range of applications, ensuring that users can rely on the gauge to provide precise pressure measurements. However, for those applications that demand even higher precision, Dwyer offers the - HA high - accuracy Magnehelic gage option. This special variant of the 2000 series provides an outstanding accuracy of within 1% of full scale.
1.2 Range
One of the most remarkable features of the Dwyer 2000 series is its extensive range options. With as many as 81 different ranges available, it can meet the diverse needs of various applications. Whether it is measuring very low differential pressures, such as those found in cleanroom environments or air - handling systems with sensitive filters, or relatively higher differential pressures in industrial processes like fluid amplifiers or hydraulic systems, the 2000 series has a suitable range.
1.3 Mechanical Design
The mechanical design of the 2000 series is centered around Dwyer's simple and wear - free Magnehelica moving parts. These parts are engineered to quickly and accurately indicate the low - pressure, positive pressure, negative pressure (vacuum), or differential pressure of air or non - corrosive gases. The gauge's ability to handle different types of pressure conditions makes it highly versatile.
The design is also highly resistant to shock and vibration, which is crucial in industrial settings where equipment is often subject to mechanical disturbances. In factories, for instance, there may be vibrations from large machinery, and in HVAC systems installed in buildings with moving parts like elevators or industrial equipment nearby, the 2000 series differential pressure gauge can maintain its accuracy and proper functioning despite these vibrations. Additionally, it has a remarkable over - pressure resistance capacity. In case of sudden pressure surges, which can occur in some industrial processes due to equipment malfunctions or operational errors, the gauge is designed to withstand these over - pressures without getting damaged.

2. Comparison with Competitors

2.1 Accuracy Comparison
When compared to many of its competitors in the differential pressure gauge market, the Dwyer 2000 series holds its own in terms of accuracy. While some competing products may offer similar accuracy levels in their standard models, the availability of the - HA high - accuracy option in the 2000 series, with its 1% full - scale accuracy and additional features like the mirrored scale and calibration certificate, gives it an edge in applications where extremely high precision is required. Some competitors may not offer such a high - accuracy variant or may charge a significantly higher price for similar accuracy levels.
2.2 Range Flexibility
The extensive range of 81 different options in the Dwyer 2000 series is far more comprehensive than what many competitors offer. Some competing differential pressure gauges may have a limited number of pre - set ranges, which may not be sufficient to cover the wide variety of applications and pressure requirements. This lack of range flexibility can force users to either compromise on accuracy by choosing a gauge with a range that is not an exact fit for their application or invest in multiple gauges to cover different pressure ranges. The 2000 series, with its wide range options, allows users to select a gauge that precisely matches their specific pressure measurement needs, providing a more cost - effective and accurate solution.
2.3 Mechanical Design Durability
In terms of mechanical design and durability, the Dwyer 2000 series' simple and wear - free Magnehelica moving parts, along with its shock, vibration, and over - pressure resistance, give it an advantage over many competitors. Some competing gauges may have more complex mechanical designs that are more prone to wear and tear, leading to reduced accuracy and shorter lifespan. Additionally, the issues associated with liquid - filled gauges, such as evaporation, freezing, and leveling requirements, which are absent in the 2000 series, are common problems in some competing products. This makes the 2000 series a more reliable choice for long - term use in harsh industrial environments and applications where equipment durability is crucial.
