Product DescriptionDissolved Oxygen Sensor for Wastewater TreatmentWhat's this product? The On-line dissolved oxygen analyzer system comprises a master controller and a fluorescence-based DO sensor. The sensor outputs RS-485 digital signals with stronger anti-interference ability. The mainframe provides multiple interface options including Analog outputs, Digital outputs and Discrete outputs.Operation principle The blue light emitted by the LED irradiates the fluorescent coating on the inner surface of the sensor cap, exciting the fluorophores which sub sequently emit red light through radiative decay. A photodiode array detects either the fluorescence intensity (FI) or measures the fluorescence lifetime (τ) corresponding to the return of fluorophores to their ground state. The higher the concentration of oxygen, the weaker the red light emitted by the sensor, and the shorter the time required for the phase fluorescent material to return to the ground state.Features1. Integrated design with EMI-resistant capabilities;2. Industrial-grade online oxygen sensing electrode for long-term stable operation3. Built-in temperature sensor with real-time compensation4. Supports salinity and barometric pressure compensation;5. Stainless steel housing, IP68 waterproof rating, suitable for diverse operating conditions6.
