MONITORING ANALOG-DIGITAL CONVERTER Russian patent published in 1995 - IPC

FIELD: automatics. SUBSTANCE: invention is intended for use in automated systems of control over technological processes. Proposed converter has operational amplifier with signal conversion, integrator, first comparator which separate input is coupled to common wire, inverter, reversible counter which separate input is connected directly to output of specified comparator and digital-to-analog converter connected in series. It also has full-wave rectifier and second comparator which output is linked to controlling input of integrator and which second input is coupled to source of reference voltage connected in series between output of integrator and separate input of reversible counter. In this case input of proposed converter is formed by potential input wire of digital-to-analog converter and potential input wire of specified operational amplifier with signal conversion. EFFECT: increased resolving power, improved vibration stability, diminished weight and dimensions. 2 dwg
