Abstract
An integral magnet vibration sensor apparatus optimizes sensor response in a non-permanently attachable package. In a preferred embodiment of the invention, the apparatus includes a housing having a magnet, a vibration sensor, and a conditioning circuit disposed within the housing. The magnet enables the apparatus to be magnetically attached to a machine. The vibration sensor senses machine vibration when the apparatus is attached to the machine, and the conditioning circuit optimizes the frequency response of the vibration sensor in a preferred embodiment by reducing the gain of the sensor output at resonance.
