INDUCTIVE DISPLACEMENT SENSOR Russian patent published in 2020 - IPC G01B7/14 

FIELD: measurement.

SUBSTANCE: invention relates to measurement equipment and can be used for measurement of linear and angular movements of objects. Inductive displacement sensor consists of a housing in which a magnetic coil and information coils are connected to an alternating current source, a preamplifier unit, wherein magnetic coil is rigidly fixed in housing, on the right and left of it through plastic partitions coaxially with it are fixed information coils, inside which there are two equal rods, separated by spring, one internal is fixed rigidly in the partition, the other is movable in the sliding bearing and the flange with the lock, to which the probe is attached to the thread, additionally in the housing there is a block-diagram of the amplifier of signals from information coils connected to the output connector fixed on the flange with the lock.

EFFECT: technical result is reduction of noise (background) and high sensitivity of sensor.
