Thermal imaging and predictive maintenance: what the future has in store

Advancement in infrared detector technology has made significant progress. Whilst there is still good reason to use single element detectors to achieve the high spatial resolution required for remote kiln shell line scanning, infrared focal plane array based thermal imaging systems bring new benefits to thermal imaging used within the cement plant. Lower costs and easier to use equipment with simple to use software open up many opportunities for plants to perform their own predictive and preventive maintenance. This provides more flexibility and faster return on capital as they can conveniently utilise the equipment for preventive and diagnostic use instead of being wholly dependent on third parties or consultants. Focal plane array based infrared cameras are now being brought into new roles within the entire plant including inside the kiln itself, where they can bring both imaging and measurement benefits that improve process control, operational efficiency and energy costs.
