CPC classification number: G01L9/125 , G01L9/0072 , G01L9/12
Abstract: A pressure sensor comprises an operating circuit and a pressure-measuring cell comprising a counter body, a measurement membrane, which is arranged on the counter body and can be deformed by a pressure to be measured, and a capacitive transducer, which has at least one membrane electrode arranged on the measurement membrane and at least one counter-body electrode arranged on the counter body. The capacitance between the membrane electrode and the counter-body electrode depends on a pressure-dependent deformation of the measurement membrane, wherein at least the membrane electrode has a temperature-dependent impedance. The operating circuit is designed to sense at least one capacitance between the at least one counter-body electrode and the at least one membrane electrode and to provide a pressure measurement value on the basis of at least one capacitance and to determine the impedance of the membrane electrode—particularly, the ohmic portion of the impedance of the membrane electrode.

Abstract: A sintered body comprises a first region which comprises a first material having a first effective coefficient of thermal expansion α1, a second region which comprises a second material having a second effective coefficient of thermal expansion α2, a transition region between the first region and the second region in which the effective coefficient of thermal expansion changes from the first effective coefficient of thermal expansion to the second effective coefficient of thermal expansion. The transition region has a sequence of layers with a mixture of at least the first material and the second material, with the mixing ratio of the layers varying in order to achieve a stepwise, in particular monotonic, change in the coefficient of thermal expansion.
