Popis: Oxygen Concentration Monitoring is an important requirement in fighter aircrafts. This paper reports the results of performance evaluation of an indigenous Zirconia Oxygen Sensor, which meets the requirements of a fighter aircraft environment. The Oxygen Sensor uses a solid state electrolyte, Zirconia stabilized with 8mol% Yttria, in the form of a Nernst Cell, which when heated above 600°C, develops an emf proportional to the ratio of partial pressures of Oxygen across its two electrodes. The reference gas used is air (21% O 2 ). The sensor performs satisfactorily in a wide range of environments faced in the fighter aircraft, such as altitudes upto 50K feet, the extreme temperatures of −40C to 65C, arrestor-hook shock, etc. These results are presented here.
