  2. Bubble sensor - Wikipedia

    en.wikipedia.org/wiki/Bubble_sensor

    Liquids have a higher dielectric constant than gas; when an air bubble is in a fluid-filled tube the capacitance is reduced and the output voltage rises. [3] The size of the bubble is inversely related to the measured capacitance. Table 1 shows an example of the characteristics of a particular capacitive sensor being researched. [4]

  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. Leak detection - Wikipedia

    en.wikipedia.org/wiki/Leak_detection

    Chris Cassidy works with an ultrasonic leak detector on the International Space Station. Escaping liquids create an acoustic signal as they pass through a hole in the pipe. Acoustic sensors affixed to the outside of the pipeline can create a baseline acoustic "fingerprint" of the line from the internal noise of the pipeline in its undamaged state.

  7. Gas detector - Wikipedia

    en.wikipedia.org/wiki/Gas_detector

    The ultrasonic gas leak detector then produces an alarm when there is an ultrasonic deviation from the normal condition of background noise. Ultrasonic gas leak detectors cannot measure gas concentration, but the device is able to determine the leak rate of an escaping gas because the ultrasonic sound level depends on the gas pressure and size ...

    en.wikipedia.org/wiki/Ultrasonic_transducer

    A curvilinear array ultrasonic transducer for use in medical ultrasonography Inside construction of a Philips C5-2 128 element curved array ultrasound sensor. Ultrasonic transducers and ultrasonic sensors are devices that generate or sense ultrasound energy. They can be divided into three broad categories: transmitters, receivers and transceivers.
