Modern Predictive Maintenance (PdM) has come a long way in recent years, with ease of use and installation both having increased significantly, while cost has similarly decreased. Conventional PdM was an expensive and time-consuming technology and, because of this, it was reserved for only the most critical facilities. The problem with this is that less costly equipment, though seemingly peripheral, can be just as essential to continuing operations, and it is instead relegated to a preventive maintenance (PM) schedule.
