Nexisense CL-406-A Residual Chlorine Sensor Product Definition
The Nexisense CL-406-A Residual Chlorine Sensor is a high-precision device used for real-time monitoring of chlorine content in water. It operates stably in various environments, ensuring the safety and compliance of water quality. This device is widely applied in drinking water treatment plants, swimming pools, food processing, cooling water systems, and more.
Measurement Principle
The Nexisense CL-406-A employs a constant voltage measurement principle using advanced electrochemical sensing technology to accurately measure the concentration of free chlorine (HClO) in water. The sensor reacts with the water sample through electrodes, generating an electrical signal that is converted into chlorine concentration values by the built-in processing unit. This principle ensures high accuracy and stability of the sensor under different water quality conditions.
Structure Analysis
The Nexisense CL-406-A is designed with a rational structure, consisting of the following main components:
Sensor Housing: Made of corrosion-resistant POM and ABS materials, ensuring long-term use in harsh environments.
Electrode System: High-sensitivity electrode design allows for quick response to changes in chlorine levels in water.
Temperature Compensation Device: Built-in automatic temperature compensation ensures measurement accuracy at different temperatures.
Output Interface: Supports RS-485 (Modbus RTU) and 4-20mA signal output for easy connection with other devices.
