2. Magnetic chip detector - Wikipedia

   en.wikipedia.org/wiki/Magnetic_chip_detector

   A magnetic chip detector is an electronic instrument that attracts ferromagnetic particles (mostly iron chips). It is mainly used in aircraft engine oil and helicopter gearbox chip detection systems. Chip detectors can provide an early warning of an impending engine failure and thus greatly reduce the cost of an engine overhaul.

3. Eastern Air Lines Flight 855 - Wikipedia

   Each chip detector had two O-rings, which served as oil seals. The replacement chip detectors were not fitted with O-rings, a fact which was not noticed by the mechanic who fitted them. After the chip detectors were fitted, each engine was motored for 10 seconds to check for oil leaks. None were found.

4. Leak detection - Wikipedia

   en.wikipedia.org/wiki/Leak_detection

   The primary purpose of leak detection systems (LDS) is to help pipeline controllers to detect and localize leaks. LDS provide alarms and display other related data to the pipeline controllers to assist decision-making. Pipeline leak detection systems can also enhance productivity and system reliability thanks to reduced downtime and inspection ...

5. Dye penetrant inspection - Wikipedia

   en.wikipedia.org/wiki/Dye_penetrant_inspection

   The oil and whiting method used an oil solvent for cleaning followed by the application of a whiting or chalk coating, which absorbed oil from the cracks revealing their locations. Soon a dye was added to the liquid. By the 1940s, the fluorescent or visible dye was added to the oil used to penetrate test objects.

6. Fluorescein - Wikipedia

   en.wikipedia.org/wiki/Fluorescein

   In 1966, environmentalists forced a change to a vegetable-based dye to protect local wildlife. [27] Fluorescein dye solutions, typically 15% active, are commonly used as an aid to leak detection during hydrostatic testing of subsea oil and gas pipelines and other subsea infrastructure. Leaks can be detected by divers or ROVs carrying an ...

7. Tracer-gas leak testing - Wikipedia

   en.wikipedia.org/wiki/Tracer-gas_leak_testing

   A tracer-gas leak testing method is a nondestructive testing method that detects gas leaks.A variety of methods with different sensitivities exist. Tracer-gas leak testing is used in the petrochemical industry, the automotive industry, the construction industry [1] and in the manufacture of semiconductors, among other uses.

9. Fault detection and isolation - Wikipedia

   en.wikipedia.org/wiki/Fault_detection_and_isolation

   Fault detection, isolation, and recovery (FDIR) is a subfield of control engineering which concerns itself with monitoring a system, identifying when a fault has occurred, and pinpointing the type of fault and its location. Two approaches can be distinguished: A direct pattern recognition of sensor readings that indicate a fault and an analysis ...
