  2. INFICON - Wikipedia

    en.wikipedia.org/wiki/INFICON

    Inficon was founded in Syracuse, New York by a group of scientists and engineers from General Electric (GE) and Syracuse University (SU), who developed a halogen leak detector in December 1969. [5] [6] [7] In January 1976, Inficon was acquired by Leybold-Heraeus GmbH a vacuum technology company. Due to this acquisition, Inficon became known as ...

  3. Gas detector - Wikipedia

    en.wikipedia.org/wiki/Gas_detector

    A gas detector can sound an alarm to operators in the area where the leak is occurring, giving them the opportunity to leave. This type of device is important because there are many gases that can be harmful to organic life, such as humans or animals. Gas detectors can be used to detect combustible, flammable and toxic gases, and oxygen depletion.

  4. 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.

  5. Leak detection - Wikipedia

    en.wikipedia.org/wiki/Leak_detection

    When a leak is determined to be valid based on set parameters, an alarm notification with leak video is generated and sent to a monitoring station. 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.

  6. 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.

  7. Geiger–Müller tube - Wikipedia

    en.wikipedia.org/wiki/Geiger–Müller_tube

    The halogen tube discharge takes advantage of a metastable state of the inert gas atom to more-readily ionize a halogen molecule than an organic vapor, enabling the tube to operate at much lower voltages, typically 400–600 volts instead of 900–1200 volts. While halogen-quenched tubes have greater plateau voltage slopes compared to organic ...

  8. Infrared open-path detector - Wikipedia

    en.wikipedia.org/wiki/Infrared_open-path_detector

    An open path detector usually costs more than a single point detector, so there is little incentive for applications that play to a point detector's strengths: where the point detector can be placed at the known location of the highest gas concentration, and a relatively slow response is acceptable. The open path detector excels in outdoor ...

  9. Residual gas analyzer - Wikipedia

    en.wikipedia.org/wiki/Residual_gas_analyzer

    RGAs would also be used as sensitive in-situ leak detectors commonly using helium, isopropyl alcohol or other tracer molecules. With vacuum systems pumped down to lower than 10 − 5 {\displaystyle 10^{-5}} Torr—checking of the integrity of the vacuum seals and the quality of the vacuum—air leaks, virtual leaks and other contaminants at low ...
