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.
These Bourdon vacuum pressure measurement gauges are low cost being quick and easy to use. However, they are very low accuracy gauges. Each tick mark in the vacuum is around 100 Torr. These Bourdon vacuum pressure measurement dial gauges are 3 inches high and have 1/4 inch NPT Male. They are made of corrosive resistant stainless steel.
