A data acquisition system which monitors the condition parameters of machinery (vibration, temperature, etc.), in order to identify changes which can be indicative of a developing fault. The use of condition monitoring allows maintenance to be scheduled, or other actions to be taken to prevent failure and avoid its consequences. Condition monitoring (CM) enables conditions that would shorten normal equipment lifespan can be addressed before they develop into a major failure. Normally used on rotating equipment and other machinery (wind turbines, pumps, electric motors, internal combustion engines, presses).
