What’s new in thermal imaging

R-124 Compressor Unit

Detecting Gas Leakage from a Refrigeration Plant CompressorFLIR Systems reports how its GF304 optical gas imaging camera has been used to detect Freon R-124 gas leaks from a refrigeration plant compressor without interrupting or shutting down operations.

Most modern refrigerants are organofluorine compounds, and while they are not ozone-depleting, some blends contain Volatile Organic Compounds (VOCs).  Freon™ R-124 is a widely used hydrochlorofluorocarbon (HCFC) based refrigerant used in centrifugal chillers employed in food production, pharmaceutical storage and air conditioning.

Refrigerant gases such as Freon R-124 are highly toxic, environmentally harmful, and heavily regulated. By detecting R-124 gas leaks early, the plant operators avoided the need for costly refrigerant replenishment, loss due to spoiled product and limited any environmental impact. Moreover, the high sensitivity, handheld FLIR GF304 enabled inspectors to pinpoint and visualize the exact source of these invisible refrigerant gas leaks faster and more reliably than with using fixed sniffer detectors as well confirming effective repairs once complete.

Solving High-Speed Automotive Testing Challenges

High speed thermal image of automotive tire braking

FLIR Systems has published a white paper that discusses how new Infrared (IR) camera technologies are providing engineers and technicians with the tools they need to address the difficulties of high-speed automotive testing.

Product research and development on internal combustion engines, brake rotors and tires, and high- speed airbags are discussed as just a few of the areas that could truly benefit from high speed, high sensitivity thermal characterization testing. Measuring temperature on objects that are moving fast is challenging. Traditional forms of temperature measurement such as thermocouples are not practical for systems in motion. Non-contact forms of temperature measurement such as spot pyrometers lack the fast response rates necessary to take accurate readings on fast moving objects or to thermally characterize a high-speed target accurately. In addition, infrared cameras with uncooled detectors are also unable to measure temperature accurately at extreme high speeds.

Without the appropriate tools for adequate thermal measurement and testing, automotive design engineers can lose time and efficiency, and risk missing defects that lead to dangerous products and expensive recalls.

The authors of the white paper discuss how in order to visualize and take accurate temperature readings on extremely fast-moving targets, you need a cooled thermal camera with a short exposure time and fast frame rate. This white paper explores thermal and quantum detector types, a camera’s ability to synchronize and trigger to external events, the importance of high sensitivity and the advantages of Longwave Infrared (LWIR) measurements.

The white paper concludes that next generation LWIR camera technologies may offer automotive engineers a solution. These cameras incorporate 640 x 512-pixel high resolution detectors that can capture images at a rate of 1000 frames per second. In addition, using Strained Layer Superlattice (SLS) detectors, these cameras offer wide temperature ranges with a combination of great uniformity and quantum efficiency beyond that of traditional MCT and QWIP detector materials. These new technologies, plus the ability to synchronize and trigger remotely, give engineers and technicians the tools they need to address the difficulties of high-speed automotive testing.

Thermal Cameras Provide Unique Insight into Material Properties

 

Composite inspection

FLIR Systems reports how its FLIR A6700 series thermal cameras with Lock-In, Transient, and Pulse capabilities can perform advanced inspections such as Non-Destructive Testing (NDT) or stress mapping, resolving temperature differences as low as 1 mK.

NDT is widely used to evaluate the properties of a material, component, or system without causing damage. FLIR A6700sc series cameras can detect internal defects through target excitation and the observation of thermal differences on a target’s surface. Thermal imaging is a valuable tool for detecting defects and points of failure in composites, solar cells, bridges, and electronics. It is also a great tool for thermal mapping of stress when performing materials testing.

Thermal non-destructive testing using a FLIR A6750 SLS longwave infrared thermal camera can detect internal defects through target excitation and the observation of thermal differences on a target surface. This camera is also proven to be a valuable tool for detecting voids, delamination, and water inclusion in composites.
