4 PREDICTIVE MAINTENANCE (PDM) SOFTWARE METHODS THAT REDUCE MACHINE DOWNTIME Maintenance managers say PDM is 4x more effective at reducing downtime than reactive maintenance. Predictive maintenance methods, such as streaming real-time data into a CMMS, reduce the chances of machine downtime over other methods. To reduce downtime with predictive maintenance, use these common methods: 1 INFRARED THERMOGRAPHY To detect excessive heat in components like bearings or circuitry 2 VIBRATION ANALYSIS To detect misalignments in rotating components 3 ULTRASOUND MONITORING To detect inaudible leaks or friction 4 LUBRICATION TESTING To detect metal particles in oil, indicating grinding Sources: http://www.plantengineering.com/fileadmin/content_files/pe/ CFE_Media_Plant_Engineering_2014_Maintenance_Study.pdf
