Abstract
A monitor attaches to a mount proximate a machine to determine the health and operating status of the machine. The monitor is preferably self-contained, having its own internal power source, electronics, and sensor suite. One or more sensors are provided to sense machine operating characteristics such as temperature, flux, and vibration. Sensor outputs are processed and analyzed by monitor electronics to determine various operating parameters, including machine speed and load, which are stored in memory. Other parameters which can be calculated and stored include cumulative time of machine operation for different categories of loads, cumulative time of machine operation over a predetermined maximum temperature, and total number of machine starts. 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 portable data collector, to communicate with the monitor and download stored data. Downloaded data can be further analyzed and statistically compared to trend data at a base computer to further ascertain the health and condition of the machin…
