ANALOG-TO-CODE CONVERTER WITH INDUCTION DETECTOR Russian patent published in 1996 - IPC

FIELD: instruments. SUBSTANCE: device may be used for conversion of output voltage of inductive detectors to code. Said inductive detectors responses to physical parameters such as movement, pressure, moment, and so on. Device has inductive detector, generator of information signal, generator of sine-shaped signal, frequency synthesizer and analog-to-digital converter. Integration interval generator and design of generator of information signal are introduced to accomplish the goal of invention. Integration interval generator has pulse counter, read-only memory unit and register, which are connected in series. Generator of information signal is designed as transformer, which provides alternating current bridge together with output elements of inductive detector. This results in possibility to suppress third harmonic and harmonics that are its multiple. Fifth harmonic is reduced by factor of six, seventh one - by factor of 8.5. This results in increased linearity of conversion response of device. EFFECT: increased precision. 4 dwg
