DISPLACEMENT SENSOR WITH HIGH RESOLUTION Russian patent published in 2024 - IPC G01B7/00 G01B7/02 

FIELD: measuring equipment.

SUBSTANCE: high-resolution displacement sensor comprises a housing made in the form of a cylinder and an inductive coil placed inside it, with a core made of a cylindrical ferromagnetic bushing equal in height to the inductive coil, closed from below by a lid, according to the invention, a non-magnetic probe is rigidly fixed inside the ferromagnetic bushing, pressed by a spacer spring, installed in the support sockets rigidly fixed on the rod and the cover, the inductive coil is connected to the oscillatory circuit of the amplifier and the signal transmitter connected to the antenna and power supply with a switch located in the top cover of the case, the transmitted signal is received by the receiver, then amplified by the amplifier, then transmitted to the decoder, analogue-to-digital converter and computer for information processing.

EFFECT: possibility of transmitting data over a radio channel, reducing interference of the measured signal, increased sensitivity and reliability of the sensor due to a simple measuring tool of a ferrite core and an inductive coil.
