Abstract

PURPOSE: To enable to automatically discriminate the cause to AE production whether it is based on the development of defect or on the plastic deformation of material, by providing the pressure unit, AE sensor, count means and AE-type discrimination circuit.
CONSTITUTION: On the surface of the pressure vessel V pressed in a plurality of cycles with the pressure unit 1, AE sensors 2aW2d are fitted, and the detection output is fed to the AE signal discrimination circuit 4. The circuit 4 feeds the AE signal to the counters 6aW6d calculating the frequency nS of AE production and the position set circuit 5. The output of the counters 6aW6d is given to the comparators 8aW8d taking the said nS as the reference value of variable setting and the display unit 9. The comparators 8aW8d produces an output when the reference value nS is equal to the production rate n calculated actually, and each output is given to the display control circuits 10aW10b. The AE-type discrimination circuit 13 receives the pressure signal when the AE production rate n is nS with repetitive pressure cycle, from the display control circuits 10aW10b, to activate alarm and display the relation of any AE sensor.
