Noncontact IR thermometers in modern maintenance

摘要

Thermography and IR pyrometers are currently widely accepted as tools in the preventive and predictive maintenance (PPM) of electrical equipment. This paper shows practical case studies of the combined use of IR cameras and IR pyrometers in the maintenance cycle. The results show that the proper use of both types of equipment can improve the overall efficiency of the maintenance cycle measured as the ratio of the number of defects correctly repaired and the total number of defects detected during inspection. With today's modern equipment the results can be further improved provided the input and output from the two instrument types can be synchronized.
