2.2 Device description
The sensor is designed to continuously measure dissolved oxygen levels in liquids. It is effective
in saving energy costs associated with aeration systems in an activated sludge process. In
addition, accurate measuring of dissolved oxygen allows for better control of
nitrification/denitrification.
This manual details installation procedures and operational features of the sensor. Menu
navigation and technical data for the MAC 080 converter can be found in the MAC 080 manual.
2.2.1 Design
The sensor is manufactured with 316SS (SS2343) stainless steel. Built-in flushing nozzles allow
for the most accurate readings with little maintenance. The electronics is protected in the
rugged casing, ensuring its reliability in very demanding environments.
The sensor has a fixed, shielded 10 m / 33 ft cable used for signal transmission between the
sensor and the MAC 080 converter. The cable sheath is made of Hytrel and is highly resistant to
aggressive materials and fluids.
