FIELD: measuring equipment.
SUBSTANCE: invention relates to measuring equipment using optical fibre. Fencing with a mobile element with a sensor pusher placed thereon, constituting an end fibre optic sensor (EFOS), comprises a body with a pusher ensuring a change in the position of the rings of the optical fibres of the sensing part, and a sensing part made of a splitter, the outputs whereof are closed with each other by an optical fibre coiled into a ring and together form a closed loop. Said ring is connected with the pusher and the body by means of rods passed inside the corresponding heat-shrinking tube together with the ring.
EFFECT: invention structurally simplifies the sensor and ensures continuous diagnostics of the operability thereof and the optical line leading thereto.
