Abstract
A monitor attaches to a mount proximate a machine to determine the health operating history and operating status of the machine. The monitor is preferably self-contained, having its own internal power source, electronics, and sensor suite. If desired, the monitor may be powered by an external power source. One or more internal sensors disposed in the monitor are provided to sense machine operating parameters such as temperature, flux, and vibration. External sensors tethered to the monitor may be positioned at varying points on and/or in the machine. Monitor electronics process sensor outputs to determine machine operating parameters such as machine speed and load. Monitor electronics are also operable to transform time domain data generated by the sensors to frequency domain data. A communications port enables a peripheral device, such as a notebook computer or a computer network, to communicate with the monitor and download stored data. Downloaded data can be further analyzed and statistically compared with trend data at a base computer to further ascertain the health and condition of the machine.
