ULTRASOUND TRANSFORMER OF ANGULAR DISPLACEMENTS Russian patent published in 2007 - IPC G01B17/00 

FIELD: the invention is used in automated technical systems in quality of an element of feedback according to angular position of the object.

SUBSTANCE: the transformer has circular acoustics lines with different radiuses, an acoustics absorber, a reflecting load, two constant magnets with a driving element, two signal electro-acoustics transformers, a former of impulses, an amplifier of recording, two amplifiers of reading, a coding and calculating block. On each acoustics line a constant magnet having a kinematical connection with the controlled object through the driving element is installed between the displacements stops. The signal electro-acoustics transformers are rigidly fastened from one side of the absorber, from the other side - the reflecting load. The output of the amplifier is switched on to the circular acoustics lines.

EFFECT: increases accuracy and resolution.
