How Pressure Gauges Work?

Answer

Most gauges are constructed with bourdon tubes to measure vacuum and pressure. The bourdon tube flexes when pressure is applied, since it naturally wants to straighten out but cannot because it is linked to a geared movement.  The linear movement is changed as it tries to flex, to a rotational one by means of small gears.  The gears in-turn cause the pointer to indicate the measured pressure, in which gauges like this are designed for clean, non-clogging liquids and gases.
