摘要： A crystal self-test circuit is used to self-test either an acoustic emission crystal or a vibration crystal installed onto one of a bearing, a bearing housing, and a machine. A crystal self-test circuit includes a multiplexer IC, which toggles between a pulse injection configuration and a signal collection configuration. In the pulse injection configuration, the multiplexer IC provides signal communication between a crystal self-test input and the sensing emission crystal. In the signal collection configuration, the multiplexer IC provides signal communication between the sensing emission crystal and a signal analyzer. In operation, the multiplexer IC applies a waveform (preferably a square wave) to the sensing emission crystal over a predetermined time period. The multiplexer IC then toggles to collect the output waveform from the sensing emission crystal and forwards the output waveform to the signal analyzer. The output signal can be amplified by a signal amplifier.

摘要： In vibration based mechanical diagnostics, algorithms may extract some feature of a component which may be used as a statistic of the components' health. A measured condition indicator (CI) corresponding to the analysis of the components' health may be a function of transmission error (TE). Because there exists a relationship between TE and the CI for a component that is faulted, the CI is correlated with power transmitted. In drive train components, power may be proportional to measured torque. In terms of diagnostics or trending of a component, it is desirable to reduce the scatter in the measured CI and account for this torque. The relationship between measured CI and torque may be captured over time. An increase in the correlation of torque with the CI would indicate an increase of TE which indicates the propagation of a fault.
