Servomex’s groundbreaking, patented Magnetodynamic Paramagnetic technology provides fast, accurate and sensitive measurement of percentage levels of oxygen.
Two nitrogen-filled glass spheres are mounted within a magnetic field, on a rotating suspension, with a centrally-placed mirror. Light shines on the mirror and is reflected onto a pair of photocells. As oxygen is attracted into the magnetic field, it displaces the glass spheres, causing suspension rotation which is detected by the photocells.
This generates a signal to a feedback system, which passes a current through a wire mounted on the suspension, creating a motor effect. This current is directly proportional to the concentration of oxygen within the gas mixture.
Unlike electrochemical technologies, a Paramagnetic cell never needs changing and offers a performance that never deteriorates - meaning reduced ongoing maintenance and a long operational life.
