Optical sensor for dissolved oxygen

June 2020 Sensors & Transducers

With its state-of-the art optical fluorescence quenching technology and digital signal processing functionality, the Jumo digiLine 0-DO S10 ensures long-term stability when measuring oxygen and temperature. Possible application areas include fish farming, sewage treatment and other sectors of water and wastewater engineering.

The sensor housing is made from tough PVC so that this Jumo digiLine can be used in both fresh and salt water. Using the innovative, user-friendly connection concept from the digiLine bus system, the device can easily and quickly be connected to the digiLine master via ‘plug and play.’ In addition, the system enables more efficient and faster cabling of plants where several parameters need to be measured simultaneously at various locations.

The device also comes with a state-of-the-art sensor management system. This system acquires and logs relevant operating data over the sensor’s entire lifecycle to optimise processes and procedures. This includes the acquisition of operating hours as well as functions designed to enable predictive maintenance such as timely notifications when calibration work is required or a sensor cap needs to be replaced.

An RS-485 Modbus RTU interface and an analog output (4-20 mA) enables easy integration into the system with field devices and process control systems. The sensor’s measuring range is 0-209 mg/l and can be used in a temperature range between -5°C and 50°C.
