Online Turbidity Sensor with Auto-Cleaning

Water turbidity is a key indicator reflecting water clarity and the content of suspended particles, widely used in water purification, industrial production, environmental monitoring and other fields. Traditional turbidity sensors are constantly immersed in water, so their probes are prone to dirt, biofilm and suspended contaminants, which lead to data drift and inaccurate measurements. Frequent manual cleaning also brings high maintenance costs and low efficiency.The FST100-ZD102 smart turbidity sensor is equipped with an intelligent auto-cleaning system. Adopting the proven 90° scattered light detection principle, it delivers high-precision, low-maintenance and uninterrupted online turbidity monitoring, suitable for various complex industrial and water environment conditions.

This sensor applies the industry-standard 90° scattered light measurement technology to guarantee superior detection accuracy. It emits light beams into water samples and precisely captures the intensity of vertical scattered light generated by suspended particles. Combined with built-in calibration algorithms and linear data processing, it accurately calculates turbidity values. A high-precision built-in temperature sensor provides real-time temperature compensation to eliminate detection errors caused by water temperature changes. Featuring fast response and strong anti-interference capability, it maintains stable and accurate monitoring data for a long time and prevents data fluctuation from external disturbances.

The auto-cleaning system is its core highlight, solving the common problems of easy contamination and frequent manual maintenance of traditional turbidity sensors. The built-in intelligent auto-cleaning module regularly cleans the optical window and effectively removes sludge, suspended solids, biofilm and sediments. It fundamentally avoids measurement deviation and light path blockage caused by probe contamination. No manual disassembly and cleaning is required, which greatly cuts maintenance frequency and labor costs, and extends the service life of the sensor. It is ideal for 24-hour unattended online monitoring and ensures stable operation and valid data around the clock.

It boasts excellent industrial compatibility. Equipped with a standard RS485 communication interface and compliant with Modbus-RTU protocol, it can be quickly connected to PLC, industrial controllers, touch screens, data recorders and other industrial devices. With stable data transmission and strong adaptability, it can be easily integrated into automatic monitoring systems to realize intelligent upgrading of water quality monitoring. Thanks to premium sealing technology, it reaches IP68 protection grade with outstanding dustproof, waterproof and anti-corrosion performance, enabling long-term underwater operation in harsh humid working conditions.

Widely applicable across industries such as water treatment, metallurgy, electric power, pharmaceutical, chemical, petroleum and food processing, the sensor detects the quantity and size of suspended particles to accurately evaluate water clarity and particle pollution. It is an essential smart device for drinking water purification, river and lake environmental monitoring, production water quality control and compliant discharge monitoring of wastewater.
