Abstract
An oxygen sensor utilizes the paramagnetic property of oxygen to determing the relative concentration of oxygen in a test gas. The test gas is supplied to the core of an electromagnet or the gap of a permanent magnet. A known magnetic flux density for the electromagnet or permanent magnet are utilized in conjunction with a Hall effect sensor to determine a change in flux which is primarily due to the oxygen component of the test gas.
