Abstract
The electromechanical acoustic emission detector of this invention comprises a plurality of sensor elements secured in an areal array on a base plate. The spacing and arrangement of the sensor elements are such that the transducer is 'tuned' to acoustic emission waves that travel along the surface of the vessel to which the transducer is attached. Because of the non-linear character of the array the transducer detects waves arriving from different directions with substantially equal sensitivity.
