The invention relates to a pressure-measuring plug for a combustion engine comprising a plug body with a body tip section facing in use the combustion chamber and comprising a passage, a ring-shaped sensing structure comprising an outer section, an inner section and an annular diaphragm, the plug body being attached to the outer section, a circular membrane comprising an outer part coupled to the outer section and an inner part coupled to the inner section, the membrane provides a sealing protecting the annular diaphragm against the harsh environment in a combustion chamber; and, a plug chamber formed by the circular membrane and the body tip section wherein the passage of the body tip section provides an open connection between the plug chamber and the combustion chamber. The passage is part of a channel structure which functions as a soot filter.
