PARAMAGNETIC
AN INNOVATIVE SOLUTION FOR PERCENTAGE OXYGEN
Our groundbreaking magnetodynamic Paramagnetic technology provides fast , accurate and sensitive measurements of percentage levels of oxygen ( O 2 ).
The Paramagnetic cell consists of two nitrogen-filled glass spheres , mounted within a magnetic field , on a rotating suspension , with a centrallyplaced mirror . Light shines on the mirror and is reflected onto a pair of photocells .
O 2 is naturally Paramagnetic , so is attracted to the magnetic field , displacing the glass spheres and causing suspension rotation which is detected by the photocells . Current is applied through a feedback coil present in the magnetic field to provide sufficient torque to return the suspension to its original position . The magnitude of this current is directly proportional to the O 2 present in the sample gas mixture .
Unlike electrochemical sensing technologies , a Paramagnetic cell never needs changing and its performance never deteriorates over time , reducing ongoing maintenance requirements and delivering a long operational life .
