Abstract

The invention relates to a pressure gauge for measuring the pressure in a combustion chamber of an engine, comprising a housing, a tappet, which is movable in the housing in an axial direction under the action of combustion chamber pressure, a sensor for detecting an axial displacement of the tappet, and a force transmitter, in order to transmit a force loading the tappet to the sensor. In accordance with the invention, the force transmitter has at least one damping section for damping flexural vibrations, at which its flexural rigidity is reduced.
