ABSTRACT:
A transducer selecting system for use in a noisy environment can operate in a vibration monitoring system using a data processor. Narrow band signals representing transducer information at selected frequencies of interest are subtracted from broad band signals representing information and background noise. The magnitude of the background noise components of each transducer is used to select from among duplicative transducers or to signal potentially unreliable information.
