Abstract: The present disclosure relates to a vibratory conveyor for transporting bulk material, wherein the vibratory conveyor comprises: a feed hopper with a hopper outlet formed at the lower end of the feed hopper, a conveying trough, and a vibration drive for driving the conveying trough with a vibration amplitude and a vibration frequency, wherein a discharge gap with a gap height is formed between the hopper outlet and the conveying trough. It is provided that the hopper comprises a hopper body and a slider that is vertically adjustable on the hopper body, wherein the hopper outlet is formed on the slider and the slider is vertically adjustable upwards from a lower stop relative to the hopper body, thereby enlarging the discharge gap.

Abstract: The invention relates to a THz sensor (2) for measuring an object to be measured (6), in particular, a pipe, the THz sensor (2) comprising: a THz transceiver (10) for emitting and receiving THz radiation, a lens (14) for bundling the THz radiation emitted by the THz transceiver (10) and emitting a THz transmission beam (8) along the optical axis (A) and for receiving a THz reflection beam (15), a support device (11), on which the lens (14) and/or the THz transceiver (10) is accommodated or fastened. Hereby, it is provided that a THz radiation-influencing compensation formation for modifying and/or reducing incident THz radiation is provided in a compensation area between the lens and the support device (11).
