Our Oxygen Sensing Technologies
Galvanic Electrochemical Sensors
These sensors operate on the principle of a galvanic cell, where the chemical reaction between the oxygen and a consumable anode produces an electric current proportional to the oxygen concentration. Renowned for their simplicity and reliability, galvanic electrochemical sensors are ideal for portable applications, gas generation and clean gas applications.
Luminescence Optical Oxygen Sensors
Utilizing the quenching effect of oxygen on luminescent dyes, these sensors provide highly accurate and stable oxygen measurements. The optical nature of these sensors ensures a quick measurement response and excellent performance in environments with varying temperatures and pressures. They are particularly suited for biomedical applications, environmental monitoring, and industrial clean gas applications .
Based on the paramagnetic properties of oxygen molecules, these sensors measure the magnetic susceptibility of the gas sample. This technology offers rapid response times and exceptional precision, making it ideal for continuous monitoring in industrial processes and laboratory settings.
Thermo-Paramagnetic Oxygen Sensors
Combining thermal and paramagnetic principles, these sensors measure the cooling effect of oxygen on a heated element within a magnetic field. The thermo-paramagnetic approach enhances sensitivity and stability, making these sensors suitable for demanding environments such as chemical processing, inerting, gas generation, pharma and biogas applications.
Employing a zirconium dioxide (ZrO2) ceramic element, these sensors operate at elevated temperatures to measure oxygen levels through the generation of a voltage based on the difference in oxygen concentration across the ceramic membrane. Zirconia sensors are highly robust and accurate, making them perfect for applications in additive manuafacturing, combustion optimization, and flue gas monitoring.
