Water Blue Green Algae Sensor

one.Water Blue Green Algae Sensor Application Environment Description

Water Blue Green Algae Sensor is used to monitor algae populations at natural levels in fresh water and is ideal for monitoring water stations, surface water and other applications.Using the characteristics of phycocyanin fluorescence excitation in blue-green algae, the intensity of its excitation fluorescence is detected by emitting a beam of light of a specific wavelength, thereby calculating the concentration of blue-green algae.It has high sensitivity, fast response and real-time monitoring capabilities, and is widely used in water quality monitoring and other fields.

Signal output: RS485 (MODBUS-RTU).

Filter detection, strong anti-interference ability.

Internal signal isolation technology has strong interference.

Good reproducibility, thermal stability, low drift, small size, fast response speed

Easy to install, simple, 3/4NPT pipe threads, easy to sink-in installation or install in pipes and tanks

Stable performance and long service life

IP68 waterproof standard

two.Water Blue Green Algae Sensor Technical Performance and Specifications

1.Technical parameters

The sensor connector is M12 aviation plug connector 5-core mother seat

three.Water Blue Green Algae Sensor Installation and Electrical Connection

1.Installation

Installation distance requirements: Keep it more than 5cm from the side wall and more than 10cm from the bottom.

Installation environment: Cannot work in strong light, try to be in a dark environment.No other fluorescent substances that can be excited can be present.

2.Electrical installation

The cable is a 4-core shielded wire, and the line sequence is defined:

Red - Power cord (12~24VDC)

Blue-ground (GND)

Green-485B

Yellow-485A

Before powering on, carefully check the wiring sequence to avoid unnecessary losses caused by wiring errors.

Note: The color of the cable may vary slightly depending on the production batch.The specific color of the cable is subject to the silk screen printing.

Four.Water Blue Green Algae Sensor Maintenance and Maintenance

1.Use and maintain

The sensor's measurement window is one of the key components to ensure the normal operation and accurate measurement of the sensor.Its cleaning requirements are crucial to ensure the accuracy and reliability of the measurement.

1.1 Maintenance method

1.Regular cleaning: The measurement window should be cleaned regularly to remove dirt, sediment and other impurities attached to the surface.The cleaning frequency depends on the measurement environment, but daily or weekly cleaning is generally recommended.

2.Use gentle detergent: When cleaning, you should choose gentle detergents and avoid using cleaners containing abrasives or acid-base ingredients to prevent damage to the surface of the measurement window.

3.Soft cloth or sponge: During the cleaning process, use a soft cloth or sponge to gently wipe the surface of the measurement window to prevent scratches or wear.

4.Avoid direct contact: Avoid touching the measuring window surface directly during cleaning to reduce fingerprint and grease contamination.

5.Rinse: After cleaning is completed, the measurement window should be thoroughly rinsed with clean water to ensure that residual detergent and dirt are removed.

6.Dry: After cleaning, gently wipe the surface of the measuring window using a dry soft cloth to remove water stains and ensure complete dryness.

7.Regular inspection: Regularly check the surface of the measurement window for damage or wear to keep the sensor running normally.

8.Avoid exposure to chemicals and high temperature environments: Avoid exposing the measurement window to harmful chemicals or high temperature environments to prevent damage or corrosion to its surface.

When the sensor has a long service life, it can be calibrated and corrected by matching the instrument.When the sensor is maintained and maintained by the above method, it means that the sensor has failed.Please replace the sensor.

1.2 Things to note

1.The measurement window contains glass components, so use sharp or hard objects to scratch the surface to prevent scratches and damage.

2.It contains sensitive optical components and precision electronic equipment inside to avoid exposing the sensor to violent vibration or impact, so as to prevent the displacement or damage of the optical parts and electronic equipment.No maintenance is required inside the equipment.

3.When not in use, appropriate dust covers or covers should be used to protect the optical parts from dust and contaminants.
