Sensor Design
When sample gas containing oxygen flows into the magneto-mechanical sensor,
the O
2
molecules are drawn toward the strong point of the magnetic field. This
causes the N
2
filled spheres to deflect even more so that the suspended dumbbell
body pivots on the platinum wire. The more O
2
present the further the dumbbell
body is deflected from its neutral position.
The position of the dumbbell is detected by a pair of photocells that receive a
light beam reflected from a mirror attached to the center of the dumbbell body.
As the dumbbell body pivots, the angle of the reflected light beam on the
photocells changes. The resulting potential difference creates a current.
