<p>The oxygen measuring cell (10) has a measuring chamber (22) with a gas inlet and a gas discharge opening. A dumbbell-shaped rotary part with two nitrogen-filled hollow bodies is arranged in the measuring chamber, where a mirror (56) is arranged at the rotary part. A device is provided for producing an uneven magnetic field in the area of the rotary part. A light emitter produces a ray of light that is transmitted on the mirror. Another device measures gas temperature in the measuring chamber. An independent claim is also included for a gas temperature determining method.</p> |
