Overview

About the WSTB1002 High Range Turbidity Sensor.

The WSTB1002 high range turbidity sensor is a probe-type sensor installed directly in the process (in situ). It works on the light scattering principle: infrared light passes into the water sample and is scattered by the particles present, and a photodetector measures the amount of light reflected back. The more particles in the sample, the more light is scattered and detected, giving a higher turbidity reading. A wiper keeps the optical surface clean for accurate readings, and the sensor communicates over RS485 Modbus RTU, making it suitable for sewage, wastewater, industrial water and tap water plants.

Features

  • Infrared light scattering measurement, up to 4000 NTU
  • Accuracy < ±2% FS
  • Wiper keeps the measuring surface clean and the reading accurate
  • SS316L stainless steel main body with PVC covers and cable
  • RS485 Modbus RTU communication, 12 V DC supply
  • Compact 60 × 256 mm probe, 1.65 kg
  • Sample calibration and slope calibration

How it works

  • An infrared light source shines into the water sample
  • Particles in the sample scatter the light
  • A photodetector measures the light reflected back, which rises with turbidity

Applications

  • Sewage treatment plants
  • Industrial production water
  • Wastewater treatment processes
  • Tap water plants
