Some articles on oxygen sensors, sensors, oxygen, oxygen sensor, sensor:

Oxygen Sensor - Automotive Applications
... Automotive oxygen sensors, colloquially known as O2 sensors, make modern electronic fuel injection and emission control possible ... Since oxygen sensors are located in the exhaust stream, they do not directly measure the air or the fuel entering the engine ... But when information from oxygen sensors is coupled with information from other sources, it can be used to indirectly determine the air-to-fuel ratio ...
Oxygen Sensor - Scientific Applications
... In soil respiration studies oxygen sensors can be used in conjunction with carbon dioxide sensors to help improve the characterization of soil respiration ... Typically, soil oxygen sensors use a galvanic cell to produce a current flow that is proportional to the oxygen concentration being measured ... These sensors are buried at various depths to monitor oxygen depletion over time, which is then used to predict soil respiration rates ...
Oxygen Sensor
... An oxygen sensor, (or lambda sensor), is an electronic device that measures the proportion of oxygen (O2) in the gas or liquid being analyzed ... The planar-style sensor entered the market in 1998 (also pioneered by Bosch) and significantly reduced the mass of the ceramic sensing element as well as incorporating the heater within the ceramic structure ... This resulted in a sensor that started sooner and responded faster ...

Famous quotes containing the word oxygen:

    All the oxygen of the world was in them.
    All the feet of the babies of the world were in them.
    All the crotches of the angels of the world were in them.
    All the morning kisses of Philadelphia were in them.
    Anne Sexton (1928–1974)
