Vibration, misalignment, or moving machinery which is not properly balanced can be deadly to a system. These things can cause leaks, and excessive wear bringing the life of any system to an early demise. All these problems have a common warning signal: increased ultrasonic energy. This ultrasonic energy is generated from the friction associated with these problems, and can be detected with AccuTrak® instruments. With experience, you will know what readings are good, and which are bad for the most common types of equipment you work on.
