METHOD FOR ULTRASONIC MEASUREMENT OF WALL THICKNESS OF HOLLOW VALVES

A method for measuring a wall thickness in hollow valves may include determining a wall thickness in a region of a valve stem using at least one ultrasonic sensor, wherein the one ultrasonic sensor may be oriented with respect to a surface on the valve stem in such a manner that an emitted ultrasoun...

Beschreibung
Zusammenfassung:	A method for measuring a wall thickness in hollow valves may include determining a wall thickness in a region of a valve stem using at least one ultrasonic sensor, wherein the one ultrasonic sensor may be oriented with respect to a surface on the valve stem in such a manner that an emitted ultrasound may be introduced into the surface in a perpendicular manner. The method may additionally or alternatively include determining a wall thickness in a region of a chamfer using the at least one ultrasonic sensor, wherein the at least one ultrasonic sensor may be positioned at a location on the chamfer at which an inner tangent in a cavity runs parallel to an outer tangent on the chamfer, and wherein the ultrasonic sensor is oriented with respect to the tangents in such a manner that an emitted ultrasound is introduced into the surface in a perpendicular manner.
