ABSTRACT:
An instrument comprising a generator feeding an electromagnetoacoustic transducer whose signals are applied to recording system.
The transducer has at least one inductance coil; arranged between the latter and an article being tested is a member with a current-conducting surface making up a closed loop, one portion thereof is inductively connected to the coil, where as the other portion is arranged close to the surface of the article being tested. Said member is made of a durable material in order to protect the coil from mechanical damage.
