Abstract
A production mold with piezo-transducers and associated signal processing amplifiers located inside it are housed in a tightly sealed, electrically shielded unit. The piezo-transducers are linked by a stranded conductor only insulated, which is cut to length in situ and led inside the shielded unit to a high-insulating terminal of the amplifier. There is no longer any need to use shielded cables between the piezo-transducer and amplifier.
