Although the Predictive Maintenance technologies themselves can get quite complicated, the basic concept of PdM is simple enough.
Most industrial equipment does not suddenly breakdown and stop working. The truth is equipment breaks down gradually, over a period of weeks or months. Furthermore, it gives off numerous warning signals along the way.
These early warning signs, such as slight changes in temperature, vibration or sound, can be detected by PdM technologies. As a result, PdM gives you time to plan, schedule, and make repairs before the equipment fails.
