Instead an organization named the Association for Intercollegiate Athletics for Women (AIAW) governed women's collegiate sports in the United States. By 1982, however, all divisions of the NCAA offered national championship events for women's athletics and most members of the AIAW joined the NCAA.
Mechanical pressure gauges are connected directly to the process fluid being measured (i.e. oil). As the process fluid pressure changes the pressure on the bourdon tube also changes which in turn moves the pointer on the gauge. Mechanical temperature gauges also utilize a bourdon tube. They have a sealed capillary tube and bulb assembly that is filled with temperature sensitive liquid that produces a proportional vapor pressure on the bourdon tube.
Gauges using C-shaped Bourdon tubes as the elastic chamber - the type shown in Figure 1 - are by far the most common. Pressurized fluid enters the stem at the bottom (which is sometimes center-back-mounted instead) and passes into the Bourdon tube. The tube has a flattened cross section and is sealed at its tip.
