It's easy for people to want to know something by attending to the object. When a machine is operating, engineers have difficulty knowing its status because they cannot see the inside. Engineers used to overhaul a machine to detect defects such as scratches and burns left in any part of the machine, but this solution will definitely impact maintenance costs because overhauling a machine requires time, labor and money. Maintenance costs are classified into internal costs such as labor, materials and instruments and external costs such as outsourcing (Al-Najjar and Alysouf, 2001). An alternative method is introduced to reduce maintenance costs, which is a method based on vibration maintenance. Like doctors, they know the illness of patients thanks to the symptoms, engineers also know the state of a machine thanks to its symptom which is vibration. Therefore, vibration-based maintenance is an effective solution to know the condition of a machine. A vibration analyzer is a device that can show the intensity of machine vibration and the characteristics of the problem, so that engineers can predict the condition of a machine. Comp...
