"High Temperature Pressure Sensor Element, Particularly For Measuring Pressures Inside Jet Engines, Method For The Production Thereof And Component For Jet Engines";
Patent: DE, No. Wo 2007/101426 A 1; submitted: 03-01-2007, granted: 09-13-2007.

The invention relates to a high temperature pressure sensor element (10; 20), in particular for jet engines, comprising
-..... a substrate (11) with an inner region (12) configured therein, a defomable membrane (13) which separates the inner region (12) from
t"-- the outer region and deforms during operation in the event of a change of pressure, and a strain gauge element (14a, 14b, 14c) g disposed on the membrane (13) for measuring the deformation of said membrane (13). The substrate (11), the membrane (13) and
M the strain gauge element (14a, 14b, 14c) are all made ofthe samehigh temperature stable material, particularly an alloy, such as a
0 nickel-based alloy. A component for ajet engine, such as for example a turbine blade for an aircraft or a rocket engine, comprises
such an integrated high temperature pressure sensor element (10; 20).
