YSI IQ SensorNet FDO® Optical Dissolved Oxygen Sensor The FDO is an optical, luminescent based DO sensor for the IQ SensorNet system. During the biological nutrient removal process at wastewater treatment plants, continuous and precise measurement of dissolved oxygen concentration is of vital importance for optimal performance and trouble-free operation. Efficiency and energy demand is mainly determined by the performance of the aeration control system. The FDO is a reliable, proven, long-term solution for continuous DO data that can help optimize your process and lower energy costs. • Intelligent Sensor Cap The sensor cap is individually factory calibrated. Calibration data is stored on a chip that is embedded in the sensor cap. No need to enter calibration coefficients. When a new cap is installed, the coefficients are recognized and sent directly to the controller terminal eliminating the need to manually enter information. Parameters: Dissolved Oxygen (optical) Temperature • Equal Path Reference System The optical measurement and reference paths are identically designed. This allows for identical aging of the components which enables accurate compensation and eliminates calibrations. That’s correct, there is no calibration required. • Green Light Technology Softer, low-intensity excitation light increases the lifetime of the cap. This translates into a two year warranty on the standard cap. The FDO’s lower energy green light excitation technology extends the sensor cap lifetime.
