Are there any oxygen sensors that measure up to 50%?.
As I understand, there are sensors that measure only in range 0-30%.
Is it possible to increase the threshold of sensitivity of the sensor?

Is it possible to increase the threshold of sensitivity of the sensor?
I don't think its possible. Perhaps you can tweak the reading sensitivity, but since the sensor are mostly analog, it's not possible. And maybe that also the reason the 2 sensors I've mentioned above have several series based on their measuring threshold.
The Bosh LSU 4.X sensor(s) are what I think you are looking for. Here are some related links:
