A Magnehelic Differential Pressure Gauge is a specific type of differential pressure gauge manufactured by Dwyer Instruments, Inc. It is a popular and widely used instrument for measuring and monitoring low-pressure differences in various applications. The name "Magnehelic" is a combination of "magnetic" and "differential," signifying the gauge's magnetic design and its ability to measure differential pressure.

Here are some key features and information about Magnehelic Differential Pressure Gauges:

1. Operation: Magnehelic gauges operate on a diaphragm principle. They consist of a flexible diaphragm that responds to changes in pressure difference across the two points being measured. The diaphragm's movement is converted into a mechanical rotation, which is then displayed on a circular dial with a pointer.

2. Measurement Range: These gauges are designed to measure low-pressure differences typically in the range of inches of water column (inH2O) or pascals (Pa). They are known for their high sensitivity and accuracy in measuring very small pressure variations.

3. Applications:

   • Cleanrooms and HVAC Systems: Magnehelic gauges are commonly used in cleanrooms and HVAC systems to monitor and control air pressure differentials to prevent contamination.

   • Filter Monitoring: They are used to monitor air filter conditions, ensuring that filters are not clogged and are functioning properly.

   • Fume Hoods and Laboratories: In laboratory settings, these gauges help maintain the proper airflow and pressure differences in fume hoods and other controlled environments.

   • Industrial Processes: Magnehelic gauges find applications in various industrial processes where precise pressure control or monitoring is required.

4. Accuracy: Magnehelic gauges are known for their high accuracy and reliability. They are designed to provide precise and repeatable pressure readings.

5. Installation: These gauges are relatively easy to install and can be mounted on walls, panels, or instrument enclosures using mounting brackets. They require a source of clean, dry, and regulated air for optimal performance.

6. Units of Measurement: Magnehelic gauges are available with various units of measurement, such as inches of water column (inH2O), pascals (Pa), millimeters of mercury (mmHg), and more, depending on the specific model and application requirements.

7. Maintenance: Regular maintenance, including calibration checks, is essential to ensure the gauge's continued accuracy and performance.

8. Additional Features: Some Magnehelic gauges come with additional features like adjustable setpoints, alarm contacts, and digital displays for more advanced monitoring and control applications.

Magnehelic Differential Pressure Gauges are well-regarded for their durability and performance in a wide range of industries and applications where precise pressure measurement and control are crucial. They are a popular choice for professionals in HVAC, cleanroom management, and industrial settings.
