Description

SMART-OXM Paramagnetic Oxygen Analyzer uses high-stability paramagnetic oxygen technology to achieve high-precision and high-repeatability oxygen measurement. Optional in 98%~100% high purity oxygen mesure range.

Principle

Oxygen is a paramagnetic substance and the volume magnetic susceptibility of other gases is much smaller than that of oxygen (except NO). The oxygen sensor is a pair of quartz glass dumbbell balls filled with nitrogen. The dumbbell balls are wrapped with platinum wires to form an electric feedback loop. The dumbbell balls are suspended in a magnetic field. When oxygen molecules are around the dumbbell balls, the oxygen molecules migrate under the action of the magnetic field, pushing the dumbbell sphere to deflect. The higher the oxygen concentration, the greater the deflection angle. This deflection will generate an electrical signal, which will be amplified by the amplifier and then form a loop through the feedback circuit. Under the action of the magnetic field, the dumbbell will be pushed back to the main equilibrium position. The current in this loop is proportional to the oxygen content. The oxygen content in the sample can be obtained by measuring the current value.
