DEVICE FOR MEASURING PARAMETERS OF NUCLEAR REACTOR PROCESS CHANNELS Russian patent published in 2003 - IPC

FIELD: measurement technology for nuclear reactors. SUBSTANCE: device used for measuring parameters of process channels in type RBMK nuclear reactors has case mounting drive, metering probe, and communicating link accommodating electric communicating circuit; one end of communicating link is secured on probe shank and other one is brought out to case; electric communicating link is connected to control unit. Communicating link is made in the form of multiple flexible communication link or metal chain whose links have two relative degrees of freedom for turning in two vertical planes and are easily falling into case by gravity. Electric communication circuit is enclosed in flexible sealed shell and disposed inside metal chain. Communicating link is passed through guide roller of drive. EFFECT: enhanced resistance of communicating link to mechanical damage and wear; simplified design. 5 cl, 3 dwg
