3.4.2

 

Sensor operation 

The acoustic emission sensor works on the piezoelectric principle. The acoustic emission is 

injected into the sensor via the sensor base (mounting surface) and inside it is converted into 

an electrical voltage by a piezoceramic element. This is amplified in the sensor and 

transmitted via the cable. 
The sensor frequency range lies in the ultrasonic range (>20 kHz). The sensor is non-

directional, i.e. the angle at which the sound wave is incident on the sensor base is not 

important.
