| 摘要 |
The invention relates to a device (100) for detecting the rotational angle of the position of a plurality of adjustable guide vanes (11) of a gas turbine (10), comprising at least three rotational angle sensors (1, 2, 3) at different locations of the gas turbine (10), wherein the rotational angle sensors are designed to measure the rotational angle (D1, D2, D3) of guide vanes at the respective locations, and comprising an analyzing unit (20) which is designed to calculate at least three rotational angle changes (Δ12, Δ23, Δ13) between each set of two different rotational angle sensors (1, 2, 3) and to provide the at least three rotational angle changes (Δ12, Δ23, Δ13). |
