The vibration data also tells us the speed of the screen. Notice in the top right hand corner of this spectrum we see the RPM = 998. This is accomplished through the fact that for each complete rotation of the shaft the screen makes one complete cycle up and down. Therefore by measuring the number of cycles per minute, we know the number of shaftWeb
