    Overview

    Online turbidity sensor is based on the principle of light scattering and employs an infrared LED light source and fiber optic transmission path design, exhibiting excellent resistance to external light interference. SUCH turbidity sensor has a built-in temperature compensation module, enabling long-term stable online monitoring in environments ranging from 0~50℃. It supports RS485 (MODBUS/RTU) communication, has an IP68 protection rating, and can be used continuously at water depths up to 20 meters, making it suitable for conventional water turbidity monitoring scenarios.

    Feature

    • Digital sensor with direct RS485 output, supporting MODBUS/RTU communication.
    • Based on the light scattering principle with a built-in temperature sensor for automatic temperature compensation.
    • Fiber-optic optical path design provides strong resistance to ambient light interference.
    • Infrared LED light source with additional optical filtering for enhanced anti-interference performance and high measurement stability.
    • Sensor surface treated with anti-corrosion passivation for reliable operation in various water environments.
    • Low-power design with internal circuitry optimized for strong electromagnetic interference resistance.

    FAQ
    ❯

    The sensor uses the light scattering principle with an infrared LED light source to measure turbidity accurately and reliably.

    ❯

    The sensor should be fully immersed in the water to be measured, avoiding air bubbles, sediment accumulation, or strong water flow directly impacting the probe.

    ❯

    Temperature may influence optical measurements, but the built-in temperature sensor provides automatic temperature compensation to ensure stable readings.

    online turbidity sensor works well for continuous monitoring
    I installed this sensor for a water treatment monitoring system and it has been running reliably. The online turbidity sensor was easy to connect with our RS485 system, and the Modbus communication worked without much trouble. The readings became stable after calibration, and the automatic temperature compensation is helpful when water conditions change. A practical solution for long-term turbidity monitoring.
