Like any system, to properly manage compressed air equipment some measurements have to be taken. Typically, some sort of data logging equipment is installed to measure various pressures, amps or power, flow, and sometimes temperatures and dewpoints. Placing this equipment on a system is like putting an electrocardiograph machine on a human heart, the heartbeat of the compressed air system in a plant can be analyzed to determine if everything is normal or if there is a problem, all without interrupting the system.

This story begins in Coburg, Germany in the year 1919. Coburg was first mentioned in a monastic document dated 1056, but to speed forward almost nine centuries, Coburg would join the Upper Franconia Region of Bavaria in 1920 where it remains today. Back here in 1919, the United States passed the 19th Amendment allowing women the right to vote and Pancho Villa was attacking Juarez, Mexico. So it was in 1919 that in Coburg a gentleman named Carl Kaeser Senior would open a small workshop producing parts for the early automotive industry, along with gear wheels and special machines for the glass industry.

High accuracy of multiple measured parameters is critical for the development of a trusted compressed air system baseline audit. The same is true for follow-on performance validation after system improvements have been implemented. The use of data acquisition systems using Modbus-interfaced transducers can aid auditors in achieving a thorough and highly accurate system performance assessment.

It was early summer, the air compressors were above the production floor on a mezzanine, and temperatures were heating up both outdoors and indoors. The compressed air system was comprised of three 500-horsepower centrifugal air compressors, and one 350-horsepower variable speed drive oil-free rotary screw air compressor.
