FIELD: measurement technology. SUBSTANCE: device has five identical displacement sensors three of which are differentially asymmetrically mounted on common platform 6 such that two of them, first and second ones, are differentially connected and the third one is differentially mounted with respect to the second one and displaced by a predetermined distance relative to the first one. Two other sensors, the fourth and fifth ones, are fixed independently with respect to each other and to the common platform and spaced from its surface by the same distance. The device furthermore has five identical measuring transducers, three adding units, four subtracting units, three multiplying units, four dividing units, memory unit and doubling unit. EFFECT: enhanced accuracy due to reduced error caused by varying distance between opposite sensors. 1 dwg
