DIgital Water Quality Sensor Fiber Optic Chlorophyll Sensor Kws-400
Support Modbus Protocal
1. Applications
The chlorophyll fiber sensor operates on the fluorescence
principle, employing a high-energy LED light source to illuminate
the water body based on the spectral absorption characteristics of
chlorophyll a. This illumination stimulates chlorophyll a in the
water to emit fluorescence at a specific wavelength, enabling the
measurement of chlorophyll a concentration.
The sensor's fiber structure exhibits outstanding repeatability and
stability, remaining unaffected by ambient light. An automatic
cleaning brush efficiently removes air bubbles, minimizing
contamination impact on measurements. Its suitability for long-term
online use, extended maintenance intervals, and enhanced stability
make it a reliable tool for chlorophyll a concentration monitoring
in aquatic environments.
2. Feature
Digital sensor, RS-485 output, support MODBUS
With automatic cleaning brush to prevent contamination and
eliminate air bubbles
Direct measurement is easier than traditional analysis methods
Continuous online monitoring and real-time control of water quality

Installation
Wiring and power supply
1. Do not use the sensor cable to lift the sensor! It is
recommended to install a cable protection cover to ensure that the
cable is powered and watertight.
2. Make sure the wiring sequence and power supply voltage are
correct before powering on!
Sensor installation
1. The sensor is recommended to be installed vertically with the
electrode measurement light window facing down, and the sensor
should be avoided from hitting the wall or other water conservancy
facilities caused by water flow. If the water flow is strong,
please fix the sensor;
2. Considering the influence of water level, the sensor should be
installed 30cm below the lowest water level, and ensure that the
measurement window is more than 10cm away from the bottom or
obstacles;
3. The sensor is installed in a position where there are no air
bubbles in the water, as far away as possible from the aeration
port.
