Although the Predictive Maintenance (PdM) 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.
The bottom line, when it comes to maintenance, is that time is money. The difference in repair costs between the time a PdM specialist can detect an equipment problem until the time an operator notices it can be huge.
In fact, one study showed that the cost of PdM-driven, proactive maintenance is half as much as emergency, breakdown maintenance. No other maintenance strategy gives you more time for advanced planning and scheduling than PdM. That is why PdM should be your number one source of planned maintenance. Also, studies have proven that a well-planned repair job typically takes only half as much time as an unplanned job. Planned work is always more efficient and less costly than unplanned work.
