  2. Oxygen sensor - Wikipedia

    en.wikipedia.org/wiki/Oxygen_sensor

    Oxygen sensor. An oxygen sensor (or lambda sensor, where lambda refers to air–fuel equivalence ratio, usually denoted by λ) or probe or sond, is an electronic device that measures the proportion of oxygen (O 2) in the gas or liquid being analyzed. It was developed by Robert Bosch GmbH during the late 1960s under the supervision of Günter ...

  3. Pulse oximetry - Wikipedia

    en.wikipedia.org/wiki/Pulse_oximetry

    Pulse oximetry. A pulse oximeter. Pulse oximetry is a noninvasive method for monitoring blood oxygen saturation. Peripheral oxygen saturation (Sp O2) readings are typically within 2% accuracy (within 4% accuracy in 95% of cases) of the more accurate (and invasive) reading of arterial oxygen saturation (Sa O2) from arterial blood gas analysis.

  4. Clark electrode - Wikipedia

    en.wikipedia.org/wiki/Clark_electrode

    Clark electrode. A schematic representation of Clark's 1962 invention, the Oxygen Electrode. The Clark electrode [1] [2] is an electrode that measures ambient oxygen partial pressure in a liquid using a catalytic platinum surface according to the net reaction: [3] O 2 + 4 e − + 4 H + → 2 H 2 O. It improves on a bare platinum electrode by ...

    Owlet, a baby monitoring device manufacturer, has received a nod from the FDA for its latest pulse-oximeter device BabySat. The approval comes after the FDA previously took the technology off ...

  6. OBD-II PIDs - Wikipedia

    en.wikipedia.org/wiki/OBD-II_PIDs

    It provides information about track in-use performance for catalyst banks, oxygen sensor banks, evaporative leak detection systems, EGR systems and secondary air system. The numerator for each component or system tracks the number of times that all conditions necessary for a specific monitor to detect a malfunction have been encountered.

  7. Blood gas tension - Wikipedia

    en.wikipedia.org/wiki/Blood_gas_tension

    Blood gas tension refers to the partial pressure of gases in blood. [1] There are several significant purposes for measuring gas tension. [2] The most common gas tensions measured are oxygen tension (P x O 2 ), carbon dioxide tension (P x CO 2) and carbon monoxide tension (P x CO). [3] The subscript x in each symbol represents the source of the ...

  8. Mass flow sensor - Wikipedia

    en.wikipedia.org/wiki/Mass_flow_sensor

    Mass flow sensor. A mass (air) flow sensor ( MAF) is a sensor used to determine the mass flow rate of air entering a fuel-injected internal combustion engine . The air mass information is necessary for the engine control unit (ECU) to balance and deliver the correct fuel mass to the engine. Air changes its density with temperature and pressure.

  9. Potentiometric sensor - Wikipedia

    en.wikipedia.org/wiki/Potentiometric_sensor

    Potentiometric sensor. A potentiometric sensor is a type of chemical sensor that may be used to determine the analytical concentration of some components of the analyte gas or solution. These sensors measure the electrical potential of an electrode when no current is present.
