Patent ID: 8154417

Claim:
A condition monitoring apparatus for securing onto and monitoring a device comprising: a signal processor configured to sample an X-axis start up vibration level input signal and a Y-axis start up vibration level input signal at the start up of the device being monitored; sample an X-axis subsequent vibration level input signal and a Y-axis subsequent vibration level input signal at a subsequent time after the startup of the device being monitored; sample a temperature sensor input signal at the subsequent time after the startup of the device being monitored; and monitor the device based at least partly on the following: (i) making an X-axis comparison between the X-axis start up vibration level input signal and the X-axis subsequent vibration level input signal; (ii) making a Y-axis comparison between the Y-axis start up vibration level input signal and the Y-axis subsequent vibration level input signal; (iii) making a temperature comparison between the temperature sensor input signal and a temperature threshold value signal; (iv) annunciating a high vibration or temperature indication for a high vibration or temperature condition associated with the device if either the X-axis comparison, the Y-axis comparison or the temperature comparison exceeds a respective threshold value associated with the device for at least two successive samples, or annunciating a normal indication.
