ABSTRACT:
A device for quality testing hot test objects, comprises at least one coolant-cooled rotatable body, and at least one transducer (for example a surface transducer coil) eccentrically mounted in or on the body to move along an endless path in close proximity to a surface of the test object. The transducer is conncted directly or indirectly to an associated sensing circuit. A device according to the invention is characterized in that the flow of coolant is adapted to take place via an inlet channel and an outlet channel, both of which are disposed close to the axis of rotation of the body, and at least one further channel extending between the inlet and outlet channel to convey coolant at least close to the transducer(s).
