RS485 Turbidity Sensor 0-1000 NTU for Raw Wastewater
1. Technical Principle & Specification
1.1 Measurement Principle
Core Technology: Based on the 90° angle scattered light measurement principle.
Working Process: A beam of light is emitted into the water sample. Particulate matter in the water scatters the light. The sensor measures the intensity of light scattered perpendicularly to the incident axis. By comparing the measured signal with the internal calibration constant, it calculates the turbidity concentration. The final value is output after analog linearization processing.
Intelligent Compensation: Integrated with a built-in temperature sensor for real-time environmental compensation, ensuring accuracy across varying conditions.
1.2 Signal Output & Compatibility
Interface: Features a standard RS-485 interface for reliable, long-distance data transmission.
Protocol: Supports the Modbus/RTU communication protocol, ensuring seamless integration with almost all industrial automation systems and SCADA platforms.
1.3 Optical System Design
Light Source: Utilizes a high-stability infrared LED light source to guarantee consistent performance and long service life.
Anti-Interference: Adopts an advanced optical fiber structure that effectively isolates and suppresses external ambient light interference, ensuring precise measurements in both bright sunlight and pitch-black environments.
2. Core Advantages & Durability
2.1 Extreme Environment Adaptability
Superior Waterproof Rating: Boasts an IP68 ingress protection rating, the highest level of waterproof certification.
Deep Water Capability: Designed to operate reliably at a water depth of up to 20 meters, making it ideal for deep river, lake, and undersea monitoring applications.
2.2 High Stability & Reliability
Low Drift Performance: Engineered for continuous 24/7 online monitoring with minimal signal drift, delivering stable and trustworthy data.
Low Maintenance: The modular and robust design simplifies cleaning and calibration procedures, reducing operational downtime and maintenance costs.
2.3 User-Centric Design
Easy Installation: Plug-and-play design with standardized interfaces, ensuring convenient on-site deployment and system integration.
Cost-Effective: Offers a long lifespan with high reliability, providing excellent long-term value and minimizing the total cost of ownership.
