"Strain" information and measurement system provides reliable continuous condition monitoring of the polar crane track beams and support consoles; measuring, processing and outputting information about the magnitude of stress-strain state in the support structures; recording the relative strain of support structures during the polar crane operation and evaluating the maximum strain.
PDI are used in measuring systems designed to monitor the current values of relative strain of the polar crane track beams and support consoles during operation of the NPP power unit.
PDI structurally consists of string strain gages (maximum number - 6 pcs.), a secondary measuring transducer and cables connecting strain gages and the secondary measuring transducer.
String strain gages are rigidly mounted in critical cross-sections on the beams and support consoles of the polar crane track at the NPP power unit.
