ABSTRACT:
In an industial installation which is inaccessible during operation, acoustic-emission testing of each measurement line is performed by means of at least one transducer and a preamplifier which is connected to an acoustic signal processing unit by means of a signal transmission line and a supply line. A potentiometer circuit placed on the supply line produces a variation in the supply voltage and remotely operates a relay for switching the measurement line to testing means comprising a local pulse generator connected between the transducer and the preamplifier.
