we report the development of different types of oxygen sensors based on yittria-stabilized zirconia (ysz) as a solid electrolyte. the conventional oxygen sensor is a concentration cell with two porous pt electrodes, one of which is exposed to air as a constant (reference) oxygen concentration and the other is exposed to automobile exhaust gas of variable oxygen concentration, depending on the a...

great effect of three way catalytic convertor (twc) performance on oxygen sensor output voltage has made the sensor (located after catalyst) as the main signal in almost all today’s twc monitoring algorithms. in this paper output voltage of nonlinear oxygen sensor is estimated using a nonlinear autoregressive with exogenous inputs (narx) model. the estimation uses ecu calculated exhaust gas flo...

background: the objective of this study was to determine the heart rate and oxygen consumption of the elderly whilst frying. methodology: in 2010, a total of 31 subjects (11 males and 20 females) from sg. merab, selangor were participated in this study. they were aged between 60 to 83 years with a mean age of 67.06 years. they were asked to perform five minutes frying task and data were measure...

For the determination of dissolved oxygen, working principle of the fiber optic oxygen sensor is studied. The sensor system calibration method and temperature compensation measures and their maintenance methods are analyzed. The dissolved oxygen sensors current widely using oxygen electrode and optical fiber oxygen sensor are compared. Optical fiber probe sensor is used in the current system, t...
