WSTB1003 Low Range Turbidity Sensor

The WSTB1003 low range turbidity sensor is an industrial online sensor with a flow-through installation, used to monitor turbidity in clean and treated water. It works on the light scattering principle: as the water sample passes through the sensor, a light beam penetrates the water and is scattered by the particles present, and a detector placed at 90° to the light source measures the scattered light. More particles scatter more light and give a higher turbidity reading. Because it keeps high accuracy in the low range up to 20 NTU, it can be used for drinking water after membrane purification.

Features

• Low range 0 … 20.00 NTU with high accuracy, suitable for drinking water after membrane water purification
• Zero drift below 0.015 NTU
• Small size, convenient for system integration
• Low water consumption, flow rate up to 300 ml/min
• Long maintenance cycle with automatic sewage discharge
• Wiper keeps the measuring surface clean for accurate readings
• RS485 Modbus RTU digital output, 24 VDC supply

How it works

• Flow-through cell: the water sample passes through the sensor
• Light source: a beam penetrates the sample and is scattered by particles
• Detector at 90°: measures the scattered light, which rises with turbidity

Applications

• Power plants
• Pure water plants
• Tap water plants
• Sewage treatment plants
• Beverage plants
• Environmental protection departments
• Industrial water and the liquor industry
• Pharmaceutical industry
• Epidemic prevention departments and hospitals
