LEAK DETECTOR Russian patent published in 2015 - IPC G01M3/04 

FIELD: measurement equipment.

SUBSTANCE: this invention relates to detection of leaks, in particular, to detection of fluid medium leaks in a hose. The proposed group of inventions comprises a sensitive device, which detects the leak, for a hose section, a hose section and a system of leak detection. At the same time the sensitive device detecting the leak for the hose section comprises a sensor, comprising optic fibre and arranged to react to presence of fluid medium, a protective sleeve, where the specified sensor is enclosed, and which is arranged for expansion and compression, when the hose section expands and compresses accordingly, and a tension facility that connects the first end of the sensor with the protective sleeve, made for application of the traction force to the sensor in the protective sleeve.

EFFECT: elimination of probability of water penetration and leaks of fluid medium transported in a hose, and also in provision of faster detection of any leaks and detection of location and type of leak.
