Top 10 Reasons Why a Strobe Light is an Analyst’s Best Friend: #3 – Frequency Confirmation

For the next two reasons, you’ll need the super duper extra special strobe light that communicates with your data collector and does phase. Requiring a sensor, the analyzer actually triggers the strobe light using the vibration signal, thereby freezing whichever component is the source. This is particularly effective on belt drives, where three separate rotational speeds exist.

Understanding spectrum analysis means understanding that the frequencies displayed are calculated with a margin of error. By using the measured signal to trigger the strobe to flash, it will flash at a rate that 100% freezes the component generating that signal, removing ALL doubt as to the source. So why would anyone rely on an assumption when you can remove all doubt by executing a simple test? I don’t know but I do know that I once found, only because of this test, a fault at a frequency that was 1 cpm different than 1x. It was, in fact, the only thing that stopped what would have been a $30,000 mistake.
