INDUCTIVE METER OF TUBULAR CHANNEL CURVE Russian patent published in 2015 - IPC G01B7/14 

FIELD: measurement equipment.

SUBSTANCE: invention relates to measurement equipment and may be used to measure curvatures of tubular channels, preferably, in nuclear power engineering. Substance: inductive meter of tubular channel curvature comprises inductive clearance sensors connected with a measurement system. Inductive sensors of movements are made in the form of magnetic conductors (5) with exciting (7) and measuring (6) windings fixed on holders, installed on the meter body, and closing magnetic elements (8), fixed on the meter body opposite to opened magnetic conductors. Exciting (7) and measuring (6) windings are installed on magnetic conductors (5) coaxially. Winding wires of these windings and their outlets (10) are made from a cable with mineral insulation in a metal tight shell. Exciting windings (7) are connected to a generator of stable DC current. Measuring windings (6) via amplifiers are connected to inlets of synchronous detectors controlled from the stable DC current generator.

EFFECT: expansion of functional capabilities of a meter.
