Nexisense ZS-206 Online Turbidity Sensor Product Definition
The Nexisense ZS-206 online turbidity sensor is an integrated measuring instrument specifically designed for real-time monitoring of turbidity in water. When suspended solids or particulate matter are present in water, its turbidity increases. The ZS-206 sensor utilizes precise optical measurement technology to quickly provide accurate turbidity values, offering data support for water quality management.
Working Principle
The ZS-206 operates on the principle of scattered light measurement. The sensor uses an infrared LED light source to emit a beam of light. When this beam shines on a water sample, suspended particles in the water cause the light to scatter. The sensor determines the turbidity of the water sample by detecting the intensity of the scattered light at a 90-degree angle to the incident light. This method offers advantages such as high sensitivity and rapid response, enabling real-time reflection of changes in water quality.
Advantages of scattered light measurement
1. High accuracy: This sensor can provide measurement accuracy of up to ±3% or ±2 NTU in different turbidity ranges.
2. Wide measurement range: Suitable for a variety of applications from clean water to high turbidity water samples, with a measurement range of 0 to 1000 NTU.
3. Automatic temperature compensation: The built-in temperature sensor can automatically correct data deviations caused by temperature changes.
Structural Analysis
The Nexisense ZS-206 online turbidity sensor is designed with practicality and durability in mind. Its main components include:
1. Light source: Stable infrared LED with a long service life.
2. Detection unit: A high-sensitivity photodetector responsible for capturing scattered light signals.
3. Encapsulation material: Waterproof design, conforms to IP68 standard, and can work for a long time in environments with a water depth of up to 20 meters.
4. Communication interface: Supports RS-485 and Modbus/RTU protocols, facilitating connection with the central control system.

Measurement method
The ZS-206 measurement method mainly involves the following steps:
1. Sampling: Immerse the sensor in the water sample to be tested.
2. Beam Irradiation: An infrared LED light source emits a laser beam, which irradiates the water sample.
3. Light scattering: Particles in water scatter light and reflect it at a 90-degree angle.
4. Data processing: The intensity of scattered light is calculated by the internal algorithm of the sensor, converted into the corresponding turbidity value, and output through the RS-485 interface.
