The Magnehelic® gage is the industry standard to measure fan and blower pressures, filter resistance, air velocity, furnace draft, pressure drop across orifice plates, liquid levels with …

In 1953, J. DwyerOmega invented the Magnehelic® differential pressure gage, a diaphragm based solution where differential pressure is applied to either side of the silicone diaphragm.

5 days ago · A Magnehelic strain gauge is a mechanical tool designed to degree the distinction in strain among points, called differential strain. The name “Magnehelic” comes from the ideas of …

It operates using a diaphragm that responds to pressure differences between two ports. This movement is transferred magnetically to a pointer on the gauge face, hence the name …
