Measuring transducer for non-destructive testing of reinforcement bars in the reinforced concrete structures

摘要

measuring transducer for non-destructive test of reinforcing bar in the construction żelbetowych, containing source arousing vibration and vibration recording elements, characterized by that,that is an unit vibration and vibration measurement system.an oscillation unit consists of a rotating disc (1) with attached to its circumference at least two cylindrical permanent magnets (2), mounted on the axle (4) by means of bearings (3),combined by the serpentine belt (8) driven. all these elements are attached to the plates wsporczej (5) equipped in the base (6).vibration measuring system consists of akcelerometru (9), the conditioning of the analogue to digital converter, and a control unit.drive (7) constitutes a crank or electric motor or pneumatic or hydraulic.method of non-destructive test of reinforcing bar in the construction żelbetowych of assessment frequency characteristics wzbudzanych in structures vibrationis characterized by the fact that vibrations are using variable magnetic field resulting from the movement torque permanent magnets.
