Nexisense COL-408-S Online Colorimetric Sensor Product Definition
The Nexisense Online Colorimetric Sensor is a high-performance water quality monitoring device specifically designed for real-time measurement of water color and turbidity. By analyzing the absorption of light at specific wavelengths, it provides accurate water quality data and is widely used in water treatment, environmental monitoring, and industrial water applications.
Working Principle
The sensor operates based on the principle of optical absorption. It utilizes two light sources: one visible light source for measuring water color and a reference light source for measuring water turbidity. By measuring the absorption of light at 470nm wavelength, combined with specific algorithms, it compensates for optical path attenuation and eliminates interference from suspended particles, achieving stable and reliable measurement results.
Structure Analysis
The Nexisense Online Colorimetric Sensor features a compact design for easy installation and maintenance. Its main components include:
Light Source Module: Contains visible light source and reference light source.
Sensor Probe: Used to receive and analyze the light absorption data from the water.
Control Unit: Processes data using built-in algorithms and outputs measurement results.
Cleaning Brush: Prevents biological adhesion to ensure measurement accuracy.
Interface Module: Provides RS-485 interface and optional 4-20mA current output.
Measurement Method
The Nexisense Online Colorimetric Sensor employs a non-contact measurement method to monitor water color and turbidity in real-time. The measurement process is as follows:
Light Emission: The visible light source emits light at a wavelength of 470nm.
Light Penetration: The light penetrates the water, with some light being absorbed by the water.
Signal Reception: The sensor probe receives the light that was not absorbed.
Data Processing: The control unit analyzes the received light signals and calculates the color and turbidity values of the water.
Result Output: The measurement results are displayed in real-time via RS-485 interface or 4-20mA output.
