YSZ oxygen sensor
YSZ oxygen sensor
(OP)
Are there any possible alternatives to these zirconia oxygen sensors. We've used them before, and work in many applications but in our nitriding furnace they don't seem to work and I can not figure out why.
Max conditions are 600 deg C, 10-3atm. I read a form on eng tips that mentioned possible causes for the sensors not working, and a common theme was thermal shocks. I do not believe that is a big issue with us.
cheers

I have a lot of expierence with these instruments on coal fired furnaces.

The N2 pressure is around 10-3atm.
JEB66, in the past ysz sensors are used that showed no signs of oxygen content, then the part would be checked and show that oxygen was present.
This may simply be that the oxygen content is so low that it doesn't register, but I have no previous experience with ysz so I don't know for sure.

Do you know why ysz sensors don't work in these environments?

I think that you would be better off with a different system for this application.
