Every good condition monitoring process should make use of vibration analysis as one of its key testing methods. Indeed, the overall point of the condition monitoring system is to reliably look for errors in the functioning of the machinery. Traditionally, professionals in the condition monitoring sector have always used vibration evaluation to detect problems in the machinery. Many condition monitoring engineers also utilize acoustic emission tests in order to obtain further information about the functioning of the machinery: this involves analyzing the energy produced when the machine encounters different amounts of stress and impact.
