Measuring principle
Optical oxygen measurement
Application
Process control in enzyme production, control of culture growth, biotechnology, food industry, general process applications
Installation
Standard process connection Pg 13.5 Installation in standard pH assemblies possible
Characteristic
Hygienic, optical sensor for stable oxygen measurement over multiple sterilization cycles Measurement possible in still water
Measuring range
0.004 to 30 mg/l 0.05 to 330 %SAT 0.1 to 700 hPa
Measuring principle
Oxygen-sensitive molecules (marker) are integrated in an optical active layer (fluorescence layer). The fluorescence layer surface is in contact with the medium. The sensor optics are directed at the back of the fluorescence layer. The sensor optics transmit green light pulses to the fluorescence layer. The markers respond (fluoresce) with red light pulses. The duration and intensity of the response signals depend directly on the oxygen contents or partial pressure.
