Optical O2 measurement in commercial installations
In the context of modernisation measures carried out in recent years at C. & A. Veltins GmbH & Co. KG brewery in Meschede-Grevenstein, Centec GmbH delivered sensors, operating on the basis of optical O2 measurement, that were installed in the filtration and filling process areas. Membrane-free, very accurate and especially low-maintenance technology is at the centre of innovative features of the instruments. At the beginning of 2010, a hand-held version, Oxytrans M, became available as a portable laboratory instrument; this operates on the same measurement principle. The compact instrument is impressive in terms of speed, high accuracy and ease of operation in a plant environment. This contribution describes the measurement principle, uses and advantages of the new systems.
