  2. Weld purging - Wikipedia

    en.wikipedia.org/wiki/Weld_purging

    After filling the base area, be it the bottom of a pipe or tank, it will continue to displace air, which rises upwards. The displaced air is purged out of a release hole at the top. If process monitoring is desired, an oxygen sensor can be used - ideally placed near the release hole, to ensure the weld container is appropriately purged.

  3. Oxygen sensor - Wikipedia

    en.wikipedia.org/wiki/Oxygen_sensor

    The type of oxygen sensor used in most underwater diving applications is the electro-galvanic oxygen sensor, a type of fuel cell, which is sometimes called an oxygen analyser or ppO 2 meter. They are used to measure the oxygen concentration of breathing gas mixes such as nitrox and trimix . [ 9 ]

    This test does not only validate the cell. If the sensor does not display the expected value, it is possible that the oxygen sensor, the pressure sensor (depth), or the gas mixture F O 2, or any combination of these may be faulty. As all three of these possible faults could be life-threatening, the test is quite powerful.

    It can be measured with a dissolved oxygen probe such as an oxygen sensor or an optode in liquid media, usually water. [1] The standard unit of oxygen saturation is percent (%). Oxygen saturation can be measured regionally and noninvasively. Arterial oxygen saturation (SaO 2) is commonly measured using pulse oximetry.

  9. Nitrogen oxide sensor - Wikipedia

    en.wikipedia.org/wiki/Nitrogen_oxide_sensor

    The majority of NO x sensors developed have been made out of ceramic type metal oxides, with the most common being yttria-stabilized zirconia (YSZ), which is currently used in the decades-old oxygen sensor. The YSZ is compacted into a dense ceramic and conducts oxygen ions (O 2−) at the high temperatures of a tailpipe such at 400 °C and above.
