The thermal imaging system includes at least one infrared (IR) fiber optic cable where a sensing end of the fiber optic cable is positioned in close proximity to a location where a crack in the structural element may occur. Infrared emissions generated as a result of crack growth are collected by the IR fiber cable and transmitted by the cable to an infrared monitoring device. The amount of heat that is detected provides an indication of whether the crack is growing, and if so, at what rate."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"IR sensor/system for detection of heating associated with crack propagation during operation of rotating equipment","description":"A thermal imaging system that detects the growth of cracks in a structural element, where the system has particular application for detecting the growth of cracks and similar defects in a turbine blad","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-9670793","license":"CC-BY-4.0-like","license_terms":"AI-generated analysis on this page (summary, layman_explanation, technical_analysis, business_analysis, faqs) may be reused with attribution and a visible link back to the canonical URL above.
