Abstract

Potentiometric oxygen sensor fabricated with yttria partially stabilized zirconia and Bi/Bi2O3 reference electrode were tested in oxygen saturated lead bismuth eutectic (LBE) and oxygen saturated Tin (Sn), respectively, in order to estimate the accuracy of the oxygen sensor prior to applying them to R&D work for MYRRHA. The accuracy of these sensors was estimated in temperature range of 673-733K by measuring the electromotive force (emf) of 8 sensors. The standard deviation on the measured emf data was about 0.79mV in the case of oxygen saturated LBE and was about 1.25mV in the case of oxygen saturated Sn. These values result in a standard deviation of 4% on the oxygen concentration in LBE which is calculated from the measured emf.
