DIGITAL DISPLACEMENT TRANSDUCER Russian patent published in 2008 - IPC G08C19/00 G01D5/20 H03M1/30 

FIELD: physics, measurement.

SUBSTANCE: digital displacement transducer relates to the field of automation and information equipment and is intended for the measurement of linear and angular displacement using scanning transformer transducers. The digital displacement transducer contains the following components connected in series: amplitude logical device (5), position code decoder (6), and reversible counters (7), as well as power supply (1) connected to the excitation winding of scanning transformer displacement transducer (2) and the input of interrogation pulse generator (5), the output of which is connected to the synchronisation input of amplitude logical device (5), voltage summator (4) is introduced to it, with the inputs connected to the two adjacent sense windings of scanning transformer transducer (2) and the output connected to the additional input of amplitude logical device (5).

EFFECT: increase in displacement measurement accuracy.
