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.
Dwyer Series A3000 PhotohelicÂ® Pressure Switch/Gauge. PhotohelicÂ® Switch/Gages function as versatile, highly repeatable pressure switches combined with a precise pressure gage employing the time-proven Magnehelic Â® gage design. The PhotohelicÂ® gage measures and controls positive, negative or differential pressures of air and compatible gases. Standard models are rated to 25 psig (1.7 bar) with options to 35 (2.4) or 80 (5.5 bar) psig. Single pressure 36000S models measure to 6000 psig (413 bar) with a 9000 psig (620 bar) rating.
