A monitor attaches to a machine or 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, and to determine when an anomalous machine operating condition is present. Monitor electronics are operable to transform time domain data generated by the sensors to frequency domain data for storage and/or analysis. 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 machine.

[ What is claimed is:] [1.]1. A monitor for being placed in sensory contact with a machine for monitoring the operation of the machine and producing an operation history, said monitor comprising:a structural enclosure;an engagement surface formed on said enclosure;a fastener for attaching said engagement surface to a mount proximate said machine so that said engagement surface is in sensory contact with the machine;a power supply for supplying electrical power to the monitor;a sensor disposed in said enclosure for sensing an operating parameter of the machine and producing sensor signals representative of the operating parameter that was sensed;a signal processor disposed in said enclosure for receiving, processing, and analyzing said sensor signals to produce sensor data corresponding to the operating status of the machine, and producing an alarm signal when the analysis of said sensor signals indicates the existence of an anomalous machine condition;an indicator for receiving alarm signals and producing a humanly perceivable indication of an anomalous machine condition when an alarm signal is received; andmemory for storing sensor data, said stored sensor data corresponding to the operation history of the machine.
