Product Description

Turbidity Sensor for Wastewater Treatment

What's this product?   

      The turbidity analyzer consists of a control unit and a turbidity sensor. The sensor outputs RS485 signals with strong anti-interference capability, while the control unit provides multiple output interfaces including analog, digital, and switch signals.

Operation principle.

      The turbidity sensor operates in compliance with the ISO7027 international standard. An LED light source emits infrared radiation through an emission fiber, illuminating suspended particles in the aqueous medium to induce scattering phenomena. The scattered light is transmitted via a receiving fiber to a photodetector, where photoelectric conversion, signal processing,and 

algorithmic computation collectively derive the sample's turbidity value.

Features

1. Integrated design with anti-electromagnetic interference capability;

2. Utilizes high-brightness infrared LED as light source to eliminate the impact of sample color;

3. Employs unique optical and electronic filtering technologies to eliminate ambient light interference;

4. Stainless steel housing with IP68 waterproof rating, suitable for diverse working conditions;

5. RS485 signal transmission with standard Modbus protocol, facilitating system integration and network configuration
