Abstract

A highly flexible ultrasonic testing system, especially well suited for testing railroad rail in track from a testing car. It includes two pulse sources (12) and (22), one (12) generating trigger pulses at a rate proportional to car speed, the other (22) generating pulses at a constant rate. A plurality of ultrasonic transducers (82v), (82h), (82w), (82w<1>) and (82z) are actuated in response to the trigger pulses. The information from the transducers is operated upon by circuit elements which are responsive to the generated pulses and include data storage capability. These elements may be altered by means of a microprocessor (16). With this system, defect indications are stored and classified and caused to activate suitable alarm indications.
