Contactless device for measuring and monitoring mechanical deformation of a solid body

Abstract

The invention relates to measurement technology, in particular to extensometry, and can be used for contactless measurement and monitoring of mechanical deformations of solid bodies.The device, according to the invention, comprises a segment of glass-insulated microwire as a sensitive wire (2), made of a ferromagnetic alloy with an amorphous structure, having a bistable behavior upon remagnetization, and a temperature sensor (3), made with the possibility of being mounted on a solid body (1). The device also comprises excitation and detection coils (4) of the sensitive wire (2) and a block for processing electromagnetic pulses (5) induced in the sensitive wire (2) upon remagnetization and the temperature values of the solid body (1), at the same time the block (5) is made on the basis of non-volatile memory, equipped with a memory configuration port (6), to which are connected a code converter and a normalization operator.
