Collection: Magnehelic Gauges

2 products

Magnehelic gauges are a specific type of differential pressure gauge that are known for their quality and durability. These Magnehelic gauges bring accuracy, durability, and ease of use to applications. While they are most commonly used to measure low to medium pressure differentials, they can also be used to monitor airflow and measure filter resistance. Learn more about Magnehelic pressure gauges below to determine whether they are the right solution to your project.

The Design of Magnehelic Pressure Gauges

Magnehelic is the merging of two words – “magnetic” and “helicoid.” Magnetic operation and helicoid scales are the backbone of Magnehelic pressure gauges, due to the following:

  • Magnetic operation – Magnehelic pressure gauges indicate pressure using a simple magnetic mechanism. The gauge holds a diagram that responds to changes in pressure by moving. Then, a magnetized pointer rotates over a circular scale to display a pressure reading.
  • Helicoid scale – The scale is helicoid-shaped, which is a spiral pattern. This allows the pressure readings to increase uniformly as you move around the scale. Our Magnehelic gauge is best utilized for measuring 0-10 PSI. 

These features work together to make Magnehelic pressure gauges appropriate for use in conjunction with industrial filters. This means they can be used for more accurate filter monitoring pressure differential measurement, pressure difference monitoring, maintenance and replacement measures, filter efficiency, energy efficiency, quality control, and more. 

Other Applications for Magnehelic Pressure Gauges

While differential pressure gauges can be used in a wide range of applications, Magnehelic pressure gauges are more specialized. 

Examples of applications for Magnehelic pressure gauges include use in:

  • HVAC systems
  • Clean rooms
  • Laboratories
  • Filter monitoring
  • Blower vacuum monitoring
  • Fan pressure
  • Duct or room pressure
  • And more!
