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. The apparatus may take the form of one or more modules and/or chipset for performing the steps and functionality of the aforementioned method.
