摘要：
A device for detecting mass particles in air flows guided in a pipe, in particular of seeds to be distributed in a seed drill. A sensor element is disposed on the pipe. The sensor element is a piezoelectric element. An impact surface is disposed on the side of the piezoelectric element facing the interior of the pipe. A damping body is arranged on the side of the piezoelectric element facing away from the interior of the pipe. A rigid base body is disposed on the side of the piezoelectric element facing away from the interior of the pipe.
