VORRICHTUNG ZUR BESTIMMUNG DER WINKELLAGE EINER DREHBAREN VERDICHTERLEITSCHAUFEL

摘要

The device (35) has a measuring surface attached to a compressor guide vane. A retaining device (41) is provided for attachment of the device at a compressor. A measuring and evaluation unit (38) comprises two laser distance sensors (37) for respectively detecting distances of the measuring surface that is unscrewable from a reference position. The angular position of the measuring surface related to its reference position is determined based on the detected distances by the measuring and evaluation unit.
