Using Bluetooth speakers that are rated for the hazardous area location in which the rotating equipment operates, Mark shows how the vibration signals can be sent to the speakers. The signals can be filtered to remove ranges to frequencies to listen for specific problems.
Mark highlights how this works by firmly pressing on the rotor kit to induce a fault. He shows how this sounds by listening to the collected data through the Bluetooth speaker.
He next shows how to acquire the data that includes the fault condition. The CSI 2140 analyzer immediately displays the fault condition as an alarm at the frequency of twice the motor turning speed. Along a typical maintenance route there may be dozens and dozens of pieces of equipment for which to collect data. Mark shows how notes can be added to the alarm conditions as they are uncovered. In this case of the fault caused by him pressing on the rotor kit, he adds a note to the alarm of a possible misalignment issue.
The last thing he demonstrates in the video is comparing the recent analysis with the past times the analysis has been performed. This comparison helps show significant changes that have occurred warranting further investigation and repair.
