FIELD: physics.
SUBSTANCE: optical fibre bearing element contains a group of optical transducers arranged thereon. Such bearing element may be represented by a tick-walled capillary tube or have another shape. The bearing element has a sealed hollow shell with a lateral wall. The lateral wall is profiled within one preset section so that to form a thin-walled part whereto the optical transducer is affixed. When the thin-walled part is bent under differential pressure thereon the differential pressure is perceived by the optical transducer. The bearing element may also have a slot in the lateral wall designed for accommodation of optical fibre. An optical temperature transducer may be additionally introduced within the optical pressure transducer proximity.
EFFECT: greater distance of optical fibres extension and possibility of placement inside oil and gas wells.
