Abstract:
A monitor that attaches to a mount proximate an electric motor which drives a piece of driven equipment, said monitor for monitoring operation of the motor or the driven equipment, or both, and producing an operation history which includes one or more machine operating parameters, said monitor comprising:a structural enclosure;an engagement surface formed on said enclosure;a fastener for attaching said engagement surface to the mount;a power supply for supplying electrical power to the monitor;at least one internal sensor disposed in said structural enclosure for sensing one or more internally sensed operating parameters of the motor and producing internal sensor signals corresponding to the one or more internally sensed operating parameters;at least one external sensor disposed external to said structural enclosure for sensing one or more externally sensed operating parameters of the motor or the driven equipment, or both, and producing external sensor signals corresponding to the one or more externally sensed operating parameters;a signal processor disposed in said enclosure for receiving and processing internal and external sensor signals to produce data corresponding to the sensed operating parameters;memory disposed in said enclosure for storing data corresponding to the sensed operating parameters; anda communications port for communicating with a peripheral device.
