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.
The system should be recovered, vacuumed (min 20 minutes) and charged. The gauges readings will depend on the ambient temperature. With the A/C turned OFF-On a cold day the pressure will be low, on a hot day the pressure will be high.The table below shows the comparison between temperature and pressure for R134a. If the red gauge is too low and the blue gauge is too high. 2  Possible fault â the compressor has lost its tolerances therefore it cannot build up enough pressure on the discharge side (red gauge) and cannot create enough suction on the inlet side (blue gauge).
