Understanding ODM Magnehelic Differential Pressure Gauges

Differential pressure gauges are essential instruments widely used in various industrial applications to measure the pressure difference between two points. Among them, the ODM Magnehelic differential pressure gauge stands out for its accuracy, reliability, and ease of use. This article will explore the features, working principles, applications, and benefits of using ODM Magnehelic gauges.

What is a Magnehelic Gauge?

Magnehelic gauges are devices designed to measure low differential pressures, typically in inches of water column. They are characterized by their unique design, featuring a dual-scale dial that allows for both positive and negative pressure readings. The term Magnehelic refers to the gauge's operation, which utilizes a magnetic sensing element combined with an analog or digital scale for precise measurement.

Working Principle

The ODM Magnehelic gauge operates based on the principles of magnetism and mechanical movement. At the heart of the gauge is a small diaphragm, which flexes in response to pressure changes. When a pressure difference is applied across the diaphragm, it causes the attached magnetic pivot to move. This movement is then translated into a rotational motion, which drives a pointer across the calibrated scale on the dial.

One of the key advantages of the Magnehelic design is its ability to provide accurate readings even in fluctuating conditions. The gauge is inherently non-intrusive, meaning it does not obstruct the flow of gas or liquid being measured, making it well-suited for various applications.
