FIELD: instrumentation.SUBSTANCE: invention relates to a device for the determination of angular position of a compressor guide blade which is set in the compressor, rotates around its longitudinal axis and for which a smooth measuring surface rotating synchronously with it is provided. The angular position of the compressor guide blade rotating around its longitudinal axis is defined by the device in semiautomatic way. For this purpose the device comprises at least one fixing unit for temporary fixation of the device on the compressor in the specified position, and a measuring unit including an angular measuring device fitted by a rotating plate able of rotation around the rotation axis at which a perpendicular protruding measuring lever extending parallel to the rotation axis is provided and meant for flat application of its free smooth end to the measuring surface.EFFECT: invention is aimed at the provision of possibility for reliable, simple and also almost error-free registration of angular positions at simultaneous insensibility of a device to damages.10 cl, 4 dwg |
