Abstract

PURPOSE:To perform position display without space, by monitor display through the retrieval of the AE wave generating position by counting the AE wave reaching time difference between the acoustic emitter (AE) sensors with counter. CONSTITUTION:When cracks are produced to the point P of the construction 11, the AE impulse from the point P propagates the construction 11, it is detected with the AE sensors S1... and the reception sequence discrimination circuit 15 determines the sequence of AE wave reception, and the count of the clock pulse of the counters 161, 162... corresponding to the sensors S1, S2... is started with the sequence signal R1 corresponding to the reception signal from sensor S1 corresponding to the first reception sequence. This count continues until the sequence signal outputted by the circuit 15 of the reception of the sensors S2..., and the count value of the counters 161, 162... is fed to the position retrieval unit 18 to the sensors S2... as the time difference reaching of AE waves by taking the sensor S1 as the reference. Accordingly, the unit 18 can determine the position of the AE wave producing point P without space and display it on the AE monitor.
