Abstract
A monitoring device for detecting acoustic vibrations in monitored objects has a plurality of several structure-borne sound sensors which are connected to a remote central electronic analyzing system. The individual structure-borne sound sensors are each acoustically coupled with a self-testing unit, which can be activated from the central electronic analyzing system. Activation of the self-testing units is performed by modulation of an operating voltage supplied to structure-borne sound sensors, without additional electric connections to the electronic analysis system.
