Abstract
A magnetomechanical gas analyzer such a paramagnetic oxygen analyzer which has a dumbbell which is rotatably suspended in the region of action of an inhomogeneous magnetic field and around which a gas to be measured flows. The dumbbell is connected, fixed in rotation, to a mirror for deflecting a light beam. In order to damp in the analyzer all kinds of oscillations which have a negative effect on stability in the balance point, and to increase the detectability and the speed of the measurement, there are least two electrically conductive surface segments which are essentially perpendicular to one another are arranged for eddy-current damping on the dumbbell or in the mechanical gearing on the dumbbell and in the region of action of the inhomogeneous magnetic field. One of the surface segments may be the mirror.
