RASTER TRANSFORMER DISPLACEMENT TRANSDUCER INTO CODE Russian patent published in 2008 - IPC G01D5/20 

FIELD: physics.

SUBSTANCE: invention is related to instrument making and may be used for measurement of linear and angular displacement. According to invention, raster transformer displacement transducer into code contains serially connected amplitude-logical device, decoder of position code and reverse counter, as well as current source, which is connected with excitation winding of raster transformer displacement detector and inlet of poll pulse shaper, the outlet of which is connected to inlet of amplitude-logical device synchronisation. Invention peculiarity consists in the fact that raster transformer displacement transducer into code is equipped with circuit of voltages control and scaling transducers, inlets of which are connected to windings of detector reading, and outlets - parallel to inlets of voltages control circuit and amplitude logical device, at that outlets of voltages control circuit are connected with control inlets of scaling transducers. Owing to this fact differential nonlinearity of displacement transduction into code may be reduced.

EFFECT: reduction of differential nonlinearity of displacement transduction into code.
