An angle measuring device serves for capturing a turning position of a rotatable shut-off body (2) of a shut-off valve (3) for a duct (4) flowed through by a fluid. The shut-off body is connected to a rotary drive (5) via a shaft. A number of permanent magnets (7, 8, 9, 10) are arranged on the shaft (6). At least one magnetic field sensor (11) is assigned to the shut-off valve (6) in order to capture magnetic field vectors (12) or components of magnetic field vectors, which especially extend radially with respect to the shaft (6). Such an angle measuring device under respective conditions in the production of mineral oil/natural gas enables a respective turning position of the shut-off body with the required precision and resolution and with simple construction and low costs. |
