Vorrichtung zum Messen von Unregelmäßigkeiten in Behälterinnenwänden mit Ultraschall

摘要

The device proposed includes ultrasonic emitters (2), an exciter for exciting the emitters to emit ultrasonic energy, the emitters (2) being disposed in groups in such a way that the ultrasonic energy emitted by each group is focused on one part of the inside wall of the container, and a detector for detecting the ultrasonic energy reflected from the inside wall of the container. The capability of such a device to detect defects is increased by virtue of the fact that the ultrasonic emitters (2) are disposed along a concave surface (4) in the device.
