摘要

The pressure sensor (10) has a housing portion having transfer element that is translationally movable relative to the housing portion. The transfer element is configured to transfer the pressure prevailing in the combustion chamber to the detection electronics (18) of the pressure sensor. The seal element for sealing of the transfer element against the housing portion, is partly provided with catalytic coating.
