Abstract
A pressure sensor that is mounted on an intake tube of an internal combustion engine which prevents icing of the pressure connection. The pressure sensor of the invention has a stublike pressure connection, which extends from an inner wall of an intake tube to approximately the middle of the intake tube or beyond the middle, and as a result the risk of icing of the pressure sensor is considerably reduced. A pressure sensor is intended especially for mixture-compressing internal combustion engines with externally supplied ignition.
