FIELD: measuring technology. SUBSTANCE: device measuring linear displacement and deformation of object incorporates three distance transmitters connected to instrument converters. First and second transmitters are installed differentially relative to controlled object and one another. Third transmitter is mounted differentially with regard to first transmitter and asymmetrically with reference to second transmitter by value of size of controlled object in direction of straight line coinciding with sensitivity axes of first and second transmitters. Device also has information processing unit that includes two subtractors, one adder, three multipliers, two dividers and storage. EFFECT: expanded functional capabilities, increased measurement accuracy and simplified design of device. 1 dwg
