  2. Tracer-gas leak testing - Wikipedia

    en.wikipedia.org/wiki/Tracer-gas_leak_testing

    As well as airbags, the air conditioning system, fuel system, and exhaust system require testing for leaks. Pacemakers and catheters have to be tested for efficacy and longevity. On planes, tracer-gas leak testing is used to quickly and safely locate fuel leaks, [3] as well as to check oxygen distribution devices and cabin pressurization systems.

  3. Helium mass spectrometer - Wikipedia

    en.wikipedia.org/wiki/Helium_mass_spectrometer

    The vacuum chamber is connected to a vacuum pumping system and a leak detector. Once the vacuum has reached the mass spectrometer operating pressure, any helium leakage will be measured. This test method applies to a lot of components that will operate under pressure: airbag canisters, evaporators, condensers, high-voltage SF 6 filled switchgear.

  4. Dye penetrant inspection - Wikipedia

    en.wikipedia.org/wiki/Dye_penetrant_inspection

    Disadvantages include the detection of only surface flaws, skin irritation, and the inspection should be on a smooth clean surface where excessive penetrant can be removed prior to being developed. Conducting the test on rough surfaces, such as "as-welded" welds, will make it difficult to remove any excessive penetrant and could result in false ...

  5. Leak detection - Wikipedia

    en.wikipedia.org/wiki/Leak_detection

    Optimal detection distance varies and is influenced by camera lens size, resolution, field of view, thermal detection range and sensitivity, leak size, and other factors. The system's layers of filters and immunity to environmental elements, such as snow, ice, rain, fog and glare, contribute to false alarms reduction. The video monitoring ...

  6. Fluorescent penetrant inspection - Wikipedia

    en.wikipedia.org/wiki/Fluorescent_penetrant...

    Fluorescent penetrant inspection (FPI) is a type of dye penetrant inspection in which a fluorescent dye is applied to the surface of a non-porous material in order to detect defects that may compromise the integrity or quality of the part in question. FPI is noted for its low cost and simple process, and is used widely in a variety of industries.

  7. Vacuum filler - Wikipedia

    en.wikipedia.org/wiki/Vacuum_filler

    The key element of a vacuum filler is the vacuum filling principle. The filling product is fed into the feed system mechanically via a hopper with actively driven feeding auger, as well as via vertical “vacuum suction”. Pre-evacuated cells of a vane cell feed system move underneath the hopper. The pressure difference relative to the ambient ...

  8. Chemical Agent Detector Paper - Wikipedia

    en.wikipedia.org/wiki/Chemical_Agent_Detector_Paper

    The M256/M256A1 Chemical Detection Kits include not only M8 Detector Paper for detecting the presence of toxins, but also enzyme-based "tickets" for identifying which agent is present. The M18 kit includes M8 sheets, "tickets", and test tubes loaded with colorimetric reagents for measuring the concentration of toxins.

  9. Agitated Nutsche Filter - Wikipedia

    en.wikipedia.org/wiki/Agitated_Nutsche_Filter

    Agitated Nutsche filter (ANF) is a filtration technique used in applications such as dye, paint, and pharmaceutical production [1] and waste water treatment. [2] Safety requirements and environmental concerns due to solvent evaporation led to the development of this type of filter wherein filtration under vacuum or pressure can be carried out ...
