The paramagnetic susceptibility of oxygen is
significantly greater than that of other common
gases, and for this reason the molecules of
oxygen are attracted much more strongly by a
magnetic field than the molecules of other
gases. Most other gases are repelled by the
magnetic field.
Three different configurations to match your needs.
NEMA 4X / IP66 waterproof and weatherproof
19 in. rack mount
Panel or bench mount
UL and CUL approved Ex-proof
Combustion Analysis
Now you can match sensor to
application for the best possible
reliability and performance.
All Systech Illinois sensors are easily
calibrated to ambient air.
For ISO purposes and in specific
applications, traceable calibration
gases can be used to meet the most
demanding quality assurance

The principle of measurement (Faraday’s
method) is based on a sensor in which a
dumbbell comprising two nitrogen-filled
spheres is arranged in rotational symmetry
within a magnetic field. If the sample gas
contains oxygen it is drawn into the magnetic
field. The nitrogen inside the glass spheres
has the opposite magnetic polarization and is
forced out of the field, causing the dumb-bell to
The degree of rotation is directly proportional
to the oxygen concentration. A mirror reflects a
beam of light onto a pair of photocells. When
the dumb-bell starts to rotate, a potential
difference is generated at the photocells. The
resulting current is amplified and conducted
around the dumbbell through windings. The
current flow generates an electromagnetic
counter moment which causes the dumb-bell
to return to its original position.
The current needed to maintain the dumb-bell
in its null position is directly proportional to the
oxygen concentration.
