|1. (WO2017168237) COMBINATION SENSOR|
|Applicants:||SCHLEUNIGER HOLDING AG
The invention relates to an assembly for automatically detecting elongate objects (W), such as cables, wires, or profiled elements, without contact. Said assembly is constructed from at least one inductive measuring system (E) and at least one first optical measuring system (D) for the object (W) in a housing (2). The inductive measuring system (E) is designed as an eddy current sensor for determining an electromagnetic characteristic of the object (W), having the half coils (E1a, E1b), which wind around the object (W) and the interior of which forms an inductive cylindrical measurement volume (Ev). Together with a capacitor (E2), the half coils (E1a, E1b) form a parallel oscillating circuit (E6), which is connected to an electronic evaluating circuit (E5). The first optical measuring system (D) is designed to determine the outside diameter (Wdo) of the object (W), for which purpose an optical disk-shaped measurement volume (DCPv) is formed between the two half coils (E1a, E1b). Optionally, the assembly is also designed to additionally determine the color in the measurement volume (CDPv) by means of at least one second optical measuring system (C) and to possibly determine the position of the object (W) within the measurement volume (DCPv) by means of a further third, virtual measuring system (P).
