Hydraulic systems are an integral part of many mobile and fixed machines. Because hydraulic components generate heat during normal operation, they are excellent subjects for thermal imaging. Quite often, failures in hydraulic systems are accompanied by a change in operating temperature. When hydraulic components are visually accessible, thermal imaging and non-contact thermometry can provide valuable data for system diagnostics. This paper will discuss the theory and operation of hydraulic systems, common system failures, and the proper application of thermal imaging for hydraulic system diagnostics.
