I think this page is misleading and inaccurate, but I am not enough of an expert to rewrite it. Firstly, Magnahelic appears to be a common misspelling of Magnehelic [1], which is a trademark owned by Dwyer instruments used to refer to their range of differential low pressure gauges. Secondly, they are used for many different applications, not ...
Ideal test indicator pushed. Prior to modern geared dial mechanisms, test indicators using a single lever or systems of levers were common. The range and precision of these devices were generally inferior to modern dial type units, with a range of 10/1000 inch to 30/1000 inch, and precision of 1/1000 inch being typical.
In physics, a gauge principle specifies a procedure for obtaining an interaction term from a free Lagrangian which is symmetric with respect to a continuous symmetry—the results of localizing (or gauging) the global symmetry group must be accompanied by the inclusion of additional fields (such as the electromagnetic field), with appropriate kinetic and interaction terms in the action, in ...
Track gauge conversion is the changing of one railway track gauge (the distance between the running rails) to another. In general, requirements depend on whether the conversion is from a wider gauge to a narrower gauge or vice versa, on how the rail vehicles can be modified to accommodate a track gauge conversion, and on whether the gauge conversion is manual or automated.
Standard National Oceanic and Atmospheric Administration rain gauge. A rain gauge (also known as udometer, pluviometer, ombrometer, and hyetometer) is an instrument used by meteorologists and hydrologists to gather and measure the amount of liquid precipitation in a predefined area, over a set period of time.
