GEAR MEASURING ANGULAR DISPLACEMENT Russian patent published in 2002 - IPC

FIELD: measurement technology, measurement of angular displacement of various objects, for example, working elements of machines, mechanisms. SUBSTANCE: angle-data transmitter of gear comprises four ring sections and screen with raster window. Conductive sensitive element with angular size of 180 degrees is placed in groove of each section. Each sensitive element is coupled to one of four inductance coils by means of coupling loop. Each of two conversion channels of gear includes differentiating transformer, time selector, amplitude detector, two rectifiers, source of reference voltage, subtracter, analog-to-digital converter and data recorder. Gear also incorporates control unit, three comparators, multiplexer, code converter, parity control circuit and registers of numbers of zone and result. Invention excludes any error in determination of number of zone and possibility of appearance of code combination across address input of multiplexer not determined by truth table thanks to adherence to rule of code formation across input of code converter. EFFECT: widened application field. 8 dwg
