Experts in dissolved oxygen measurement

A solution for every industry The dissolved oxygen sensor range from Endress+Hauser covers many applications, from controlling the aeration of activated sludge basins in wastewater treatment and residual oxygen measurement in power station boiler feedwater, to controlling fermentation in biotechnology and food processes and assessing color and taste in the production of red wine. Established and new sensor technologies There are two different types of sensory measuring technology: the well-known and tried-and-tested amperometry in which oxygen concentrations are converted to electric currents, and the optical method of fluorescence quenching. In the latter method, the fluorescing light of an oxygen-sensitive molecule is used to determine the concentration. The signals are then further processed in the transmitter to obtain the desired reading. Flexible measuring point concept Channels, pipes, tanks ... no problem. The flexible measuring point concept covers all configurations. Oxygen sensors from Endress+Hauser are designed for use in channels and basins as well as for installation in pipes and tanks. The wide range of assemblies available means that the sensor can be securely positioned where it is needed.

These assemblies include the CYA112 immersion assembly, the COA250 flow assembly and the COA451 retractable assembly. This strategy of flexibility is completed by the Liquiline platform which offers an extremely user-friendly and transparent operating concept. Superb product quality Sensor production is highly automated. Testing is also performed on a fully automated test stand. Here, the zero point, slope and constancy of the sensors are checked and the results are documented. This guarantees the consistently high product quality. Benefits • A wide range for all applications • Technologies for different measuring requirements • Flexible installation • High-quality products guaranteed
