Probe appts. for non-destructive workpiece testing

摘要

The arrangement performs testing with ultrasonic waves using several adjacent probes, each with a transmission coil and a reception coil (22,24) and mounted on a magnetic concentrator (26). A setting material attached to the concentrator carries a protective plate. The wires of the transmission and reception coils are embedded in an adhesive (40) with large elastic damping and are attached to each other and to the magnetic field concentrator using the same adhesive. The adhesive can be a 2 component epoxy resin type.
