ABSTRACT:
A self-contained probe for testing of buried pipe by analyzing acoustic emissions produced under increasing stress which comprises an elongated tubular body with a hardened metallic point at one end which is placed against the pipe. The body of the probe also contains an acoustic transducer, a preamplifier, and an integral power supply. The probe receives acoustic emissions from the pipe under test, transforms acoustic signals into electrical voltages, preamplifies those voltages, and transmits them to associated facilities for computer analysis.
