PRIMARY CONVERTER FOR MEASURING DIAMETERS OF PARTS AND HOLES Russian patent published in 1999 - IPC

FIELD: measurement technology, automation of technological processes in mechanical engineering. SUBSTANCE: primary converter to measure diameters of parts and holes has sensitive element in the form of section of cylindrical deceleration system which is placed in electron circuit converting delay tine to informative signal. Cylindrical deceleration system presents two-wire line which one conductor is made in the form of cylindrical spiral and the other conductor has form of cylinder with through slits , two as minimum, arranged in symmetry along generating lines. EFFECT: high sensitivity of converter while measuring diameters of parts and holes. 3 cl, 7 dwg
