The fabrication and operation of a new thick film type of limiting current oxygen sensor is demonstrated that utilizes yttria (8% mol) stabilized zirconia (YSZ) as oxygen ion conducting solid electrolytes and dense La0.8Sr0.2CoO3(LSC) as diffusion barrier. The oxygen sensor shows a near linear response between 0 to 10.5% O2in argon at 1023K. The advantages of the sensor are simple construction, low cost and potential long term stability.
