Principle Overview The oil-in-water sensor uses the characteristic that oil substances will produce fluorescence under ultraviolet light, and measures the fluorescence intensity to infer the concentration of oil substances. Specifically, the sensor uses ultraviolet light as the excitation light source to irradiate the water sample to be tested. After the oil substance absorbs ultraviolet light, it will stimulate fluorescence, and the fluorescence signal is received by the photo detector and converted into an electrical signal. By measuring the strength of the electrical signal, the concentration of oil substances in the water sample can be inferred.
Workflow Ultraviolet light irradiation: The ultraviolet light source inside the sensor emits ultraviolet light and irradiates it into the water sample to be tested.
Fluorescence generation: After the oil substance in the water sample absorbs ultraviolet light, it will stimulate fluorescence.
Fluorescence detection: The photo detector in the sensor measures the intensity of this fluorescence.
Signal conversion: The signal processing circuit converts the output of the photo detector into an electrical signal proportional to the amount of oil in the water. Data analysis: By analyzing the strength of the electrical signal, the concentration of oil substances in the water sample can be obtained.
Features and applications The oil in water sensor has high sensitivity and can detect soluble and falsifiable oils. It is suitable for a variety of water quality monitoring scenarios, such as oil field monitoring, industrial circulating water, condensate water, wastewater treatment, surface water stations, etc. In addition, it can also monitor the content of crude oil (benzene and benzene homologous) in water sources such as reservoirs and water plants in real time online, play an early warning role, and protect the safety of water sources.
Practical application The oil in water sensor has a wide range of functions in practical applications, including but not limited to the following aspects: Monitoring the water quality of water sources: ensuring the safety of drinking water, and timely discovering pollution sources and ensuring water supply safety by continuously monitoring oil substances in water sources. Monitoring sewage treatment plant emissions: ensuring that the discharge water quality of sewage treatment plants meets the emission standards to avoid secondary pollution to the environment. Monitoring rivers, lakes and other water bodies: assessing the pollution status and providing a basis for pollution control. Early warning and emergency response: It has real-time monitoring and early warning functions, and can issue an alarm in time when abnormal conditions are found, providing valuable time for emergency response and reducing losses caused by pollution. Scientific research: Through the monitoring data of this sensor, we can deeply understand the distribution, migration and transformation of oil substances in water bodies, and provide a scientific basis for environmental protection and governance.
In summary, the oil in water sensor monitors the oil content in water bodies through ultraviolet fluorescence method, has high sensitivity and broad application prospects, and is an indispensable and important tool in modern environmental monitoring and industrial production.
