The Making of a Market Leader – The Magnehelic® Differential Pressure Gage
The name of the Magnehelic® Differential Pressure Gage was derived from the terms Magnet and the Helix. The Magnehelic® Gage is a simple yet elegant solution, which solved a problem faced by customers who wanted to measure low differential pressure. Historically the industry measured differential
pressure with a liquid filled manometer. The manometer worked on the principle that the difference in air pressure is measured as a function of gravity and liquid density. The challenge, however, was that the liquid in the manometer evaporates over time. This means that individuals would need to regularly add more liquid and re-calibrate the device.
