FIELD: devices for remote convertion of resistance changes of relative pickups; may be used to characterize two data in bridge circuits with three-wire communication line. SUBSTANCE: converter comprises resistive temperature pickup, resistive pressure pickup, four uncontrolled keys (diodes compensation and balancing resistors, differential amplifier and two-polar commutated current source. EFFECT: increased operational reliability. 1 dwg
