Abstract
An electromotor is mounted on a support and has a shaft extending into the silo or the like. The shaft, which is rotated by the electromotor, carries a blade which contacts the material in the silo when the material rises to a predetermined level. This prevents the blade and shaft from further rotating, and results in the generation of a signal. A free-wheeling device connects the shaft with the motor so that the shaft and motor are coupled for joint rotation in only one direction, but not in the opposite direction.
