Webinar Description: 
In this webinar, we’ll take a look at six specific case studies for condition monitoring of rotary screw compressors. HD condition monitoring technologies have made this quite easy and reliable.

• Many rotating parts with different RPMs in the same machine makes it difficult to identify the origins of the measured signal and keep track of the signals of interest.
• Signals from rotating part is “interfered” by the signals generated from the compression of the air
• Fast variation of RPM during data acquisition can occur. Due to resonances, measured signals may not be” linear” to RPM variations
• Load variation during measurements is common
• It can be difficult to attach a transducer in a suitable way for picking up high frequency signals.
• Frequency controlled motors can generate a wide variety of signal patterns that can be challenging to interpret.
