Magnehelic pressure gauges were developed to address which of the following?

Magnehelic pressure gauges were specifically designed to overcome the disadvantages associated with traditional manometers. Unlike manometers, which can be limited in their measurement capabilities due to factors such as fluid properties, siphoning issues, and the need for clear visibility of the measurement column, Magnehelic gauges utilize a different operational principle that allows for more versatility in various applications. They use a mechanical diaphragm and a magnetic sensing method to provide accurate pressure readings without the need for liquid, making them more reliable in a range of environments. This makes them particularly advantageous in situations where changes in pressure need to be monitored accurately and consistently without the complications that can arise from manometer use.

The focus of Magnehelic gauges on resolving the inherent challenges of manometers is what sets them apart and underscores the correctness of the response regarding their intended purpose.
