Dear BOSCH,
We are interested in using your oxygen sensors in the SOC steam electrolysis process in order to monitor the partial pressure of oxygen in the range of %O2 : 10-24 to 10-12 %.
We have good experience using zirconia based oxygen sensors at 700C in a hydrogen/steam atmosphere. We have used home made zirconia based oxygen sensors and also commercial ones from e.g. www.econox.com. I think that these are referred to as planar zirconia sensors or narrowband sensors.
Can you help us picking a BOSCH sensor of the planar zirconia sensors/narrowband sensors that gives a DC voltage signal between 0 – 1.2 V and has a thermocouple for measuring the temperature of the cell. In that way we can calculate the pO2 knowing the voltage (E) and the temperature (T) according to the Nernst equation for an oxygen concentration cell with air as a reference gas.
E=RT/nF * ln(pO2/0.21)
We hope that you can help us.
