An infrared camera is one of the best tools for performing regular reliability tests on a hydraulic system. It is also invaluable when troubleshooting heat, speed and pressure issues. In any hydraulic system, some lines will be at, above and below the oil temperature in the reservoir. The key is to know which lines should be cool, warm and hot. If checks are made when the system is operating normally, a reference can be established. By regularly conducting the following tests, a faulty component can be found, many times before it shuts down the machine.
