Oxygen sensor for float production lines
article
The development of a special oxygen sensor for the continuous measurement of equilibrium oxygen pressure and oxygen content in the float bath of a float-glass production line was discussed. The measuring principle is based on an electrochemical cell where the core of the sensor consist of a metal-metal oxide mix in a fully-yttria-stabilized zirconia cell. It was found that the oxygen content does not exceed the maximum solubility at the cold end of ~10 ppm along the entire length of the bath, despite the high oxygen solubilities. The sensor recorded a sudden oxygen increase as a result of the water release in the tin bath. It was observed that the released water oxidized the tin bath and furnace atmosphere rapidly. It was estimated that the tin dripping time span could have been decreased from 30 to ~23 h, which would have decreased production loss considerably.
