Abstract: A high-temperature pressure sensor element for power units includes a substrate, in which an interior space is developed, a deformable membrane, which separates the interior space from the exterior space in order to deform when the exterior pressure changes, and a strain measuring element, which is arranged on the membrane, for measuring the deformation of the membrane. The substrate, the membrane, and the strain measuring element are manufactured from the same high-temperature-stable material, such as an alloy. By way of example a nickel base alloy may be used. A component for a power unit, such as a turbine blade for an airplane or rocket engine, includes an integrated high-temperature pressure sensor element of this type.

Abstract: An electron beam is used to generate x-ray radiation in a workpiece, which radiation emerges on the workpiece back at sufficiently thin points of the workpiece and is detected by means of an x-ray radiation detector. Based on the x-ray radiation intensity and the momentary beaming-in position of the electron beam, the surface structure on both sides as well as the local material thickness can be determined. Based on such values, workpieces and/or workpiece treating systems can be adjusted, and vertical material removal in a material-removing workpiece treating system can be controlled.
