Abstract: Apparatus featuring a signal processor or signal processing module configured to: receive signaling containing information about a sampled leakage magnetic flux sensed from a motor, a motor load profile containing a learned leakage magnetic flux sensed from the motor and stored during a learning stage, and a user selectable band of tolerance related to the motor load profile to trigger an alarm condition for the motor; and determine corresponding signaling containing information about whether to trigger the alarm condition for the motor if the sampled leakage magnetic flux is outside the user selectable band of tolerance of the motor load profile, based upon the signaling received. The leakage magnetic flux may be sensed by, and/or received from, a motor flux leakage sensor arranged on an external surface of a frame of the motor.

Abstract: The present invention provides a new and unique method and apparatus for monitoring a device, such as a pump. The device may also include a fan, compressor, turbine or other rotating or reciprocating piece of machinery. In one embodiment, the method features sensing in a first device both a start-up vibration at a start-up time after the first device is affixed to a second device to be monitored and a subsequent vibration level at a subsequent time after the start-up time, and providing both a start-up vibration level signal containing information about the start-up vibration level of the second device, and a subsequent vibration level signal containing information about the subsequent vibration level of the second device; and monitoring in the first device the condition of operation of the second device based on a comparison of the start-up vibration level signal in relation to the subsequent vibration level signal.
