A detection device for detecting a diameter and/or composition of a welding wire and/or welding electrode for a welding device, includes an oscillating circuit, which has a coil through which the welding wire and/or welding electrode can be passed. The device further include an evaluation unit connected to the oscillating circuit for determining at least one first oscillating circuit parameter which is characteristic of an attenuation of an oscillation signal occurring in the oscillating circuit, and at least one second oscillating circuit parameter which is characteristic of a signal frequency f of the oscillation signal occurring in the oscillating circuit. The evaluation unit detects the diameter and/or composition of the welding wire passed through the coil of the oscillating circuit and/or of the welding electrode using the determined oscillating circuit parameters.

Detection device (1) for detecting a diameter and/or composition of a welding wire (5) and/or welding electrode (5) for a welding device, the detection device (1) having: an oscillating circuit (2), which has a coil (2A) through which the welding wire (5) and/or welding electrode (5) can be passed; and an evaluation unit (3) connected to the oscillating circuit (2) for determining at least one first oscillating circuit parameter (SKP1) which is characteristic of an attenuation of an oscillation signal occurring in the oscillating circuit (2) and at least one second oscillating circuit parameter (SKP2) which is characteristic of a signal frequency f of the oscillation signal occurring in the oscillating circuit (2), the evaluation unit (3) detecting the diameter and/or composition of the welding wire (5) passed through the coil (2A) of the oscillating circuit (2) and/or of the welding electrode (5) by means of the determined oscillating circuit parameter (SKP1, SKP2).

A sensor for measuring a thickness of a layer of a grain/residue mixture as the layer is transported through a cleaning arrangement of a combine harvester. The sensor is mounted on a support surface of a grain pan or a sieve of the cleaning arrangement and comprises a tower-shaped support structure with sensor elements attached to the structure and forming a vertical stack of sensor elements, so that a number of sensor elements is submerged in the layer and a number of sensor elements extends above the layer. The sensor elements are configured to measure an electrical property that changes as a function of immediate surroundings of the sensor elements. The sensor elements are configured to be read out independently from each other.
