Online turbidity sensor Achieves Precision Water Quality Monitoring via Optical Scattering Technology

Online turbidity sensor utilizes the 90° scattered light method to detect particle concentration in water, optimizing data through temperature compensation algorithms. It features high precision and low power consumption, supports customizable measurement ranges and standard communication outputs, and is suitable for online water quality monitoring across various industries.

Online turbidity sensor is a core optical detection device in the field of water quality monitoring. It primarily employs the 90° angle scattered light method to measure turbidity. By continuously illuminating the liquid with a light source and capturing the intensity of light scattered by suspended particles, it accurately converts the data into particle concentration and turbidity values using linear processing. It serves as a key device for routine monitoring in diverse water treatment scenarios.

To ensure measurement accuracy in complex environments, Online turbidity sensor incorporates an automatic temperature compensation algorithm. This effectively mitigates the impact of ambient temperature fluctuations on optical data, maintaining measurement precision within ±1% and temperature detection accuracy within ±0.3°C. Its high resolution of 0.1 NTU allows for the precise detection of subtle changes in water turbidity. The device offers flexible measurement ranges: a default of 0–1000 NTU, with customizable options of 0–40 NTU and 0–3000 NTU to meet specific water quality monitoring requirements.

Designed for continuous industrial operation, Online turbidity sensor operates on a wide DC 12V–24V power supply with a power consumption of only 0.2W, ensuring energy efficiency and operational stability. It utilizes the RS-485 (Modbus/RTU) standard for industrial communication, providing stable data transmission and strong compatibility for direct integration with centralized water quality monitoring systems. Featuring an immersion-style design, the device comes with standard 3/4 NPT mounting threads and a 5-meter cable; the installation process is straightforward, making it suitable for monitoring water in various tanks and pipelines. The Online turbidity sensor features an ABS housing and an IP68 protection rating, enabling stable operation in standard aqueous environments at temperatures of 0–50°C and pressures up to 0.2 MPa; it also boasts a storage temperature range of -5°C to +65°C, demonstrating exceptional environmental adaptability. The device supports a two-point calibration mode, allowing for periodic calibration and ensuring data stability during long-term use. Currently, it is widely utilized in sectors such as municipal water supply, drinking water treatment, wastewater treatment, integrated purification, and pulp and paper manufacturing, providing continuous, accurate data to support water quality compliance and control.
