Product Overview

The SUP-ADU3500 Pressure-Compensated Turbidity Sensor is designed for continuous online turbidity monitoring in water quality applications. Based on the 90° laser light scattering measurement principle, it provides high-precision turbidity detection with fast response and stable long-term operation. Its pressure-resistant flow channel design reduces bubble interference, while the self-cleaning optical window helps extend maintenance intervals. The compact structure makes it ideal for integration into drinking water, filtration, and industrial water monitoring systems.

Key Features

  • Provides sensitive turbidity measurement with a detection limit down to 0.005 NTU, suitable for high-quality water monitoring applications.
  • Uses a 660 nm laser light source and 90° scattering method to achieve reliable turbidity measurement with excellent stability.
  • The pressure-resistant structure minimizes bubble accumulation and improves measurement reliability in continuous water sampling systems.
  • The integrated self-cleaning design reduces contamination on the optical surface and extends maintenance intervals.
  • Supports 4–20 mA output and RS485 Modbus-RTU communication for easy integration with PLCs, SCADA systems, and industrial controllers.
  • Small and lightweight structure allows easy installation in online monitoring equipment and water analysis systems.

FAQ

What is the measurement principle of the SUP-ADU3500 turbidity sensor?

The sensor uses a 90° laser scattering method. A 660 nm laser beam is emitted into the water, and the scattered light intensity from suspended particles is converted into a turbidity value.

Does the sensor require frequent cleaning?

No. The self-cleaning optical window design helps reduce contamination buildup and extends maintenance intervals.

What applications is this sensor mainly used for?

It is mainly used for drinking water, filtration systems, pipeline water quality monitoring, swimming pools, and surface water monitoring.

How does the pressure-compensated design improve measurement performance?

The pressure-resistant flow channel reduces bubble accumulation during measurement, helping maintain stable and accurate turbidity readings.
