KBG602 Online Blue Green Algae Sensor Support RS-485 Modbus/RTU Protocol Monitoring Red Algae

1.Working Principle

The blue green algae sensor utilizes the characteristic that the blue green algae has an absorption peak and an emission peak in the spectrum. The spectral absorption peak of the blue green algae emits monochromatic light to the water, and the blue green algae in the water absorbs the energy of the monochromatic light, releasing another wavelength. The monochromatic light of the emission peak, the light intensity emitted by the blue green algae is proportional to the content of blue green algae in the water.

2.Feature

• Monitoring the concentration of micro algae in the ocean harbor

• Monitoring green algae and blue algae such as rivers and lakes

• Monitoring red algae

• Determination of green algae concentration in the treatment of green algae cultivation equipment

• Support RS-485 (Modbus/RTU protocol)

• Convenient, fast, stable and easy to maintain

5. Installation and Electrical Connection
5.1 Installation

 
Installation distance requirement: keep more than 5 cm with the side wall and 20 cm or more with the bottom.

5.2 Electrical Connection

a) Red line - power cord (12 ~ 24 V DC)
b) Black line - ground (GND)
c) Blue line - 485 A
d) white line - 485 B
e) bare wire - shielded wire
After wiring is completed, it should be carefully checked to avoid incorrect connections before powering up.

Cable specification: Considering that the cable is immersed in water (including sea water) for a long time or exposed to the air, the cable has certain corrosion resistance. The outer diameter of the cable is Φ6 mm and all interfaces are waterproof.

6 Maintenance

6.1 Maintenance Procedures and Methods

6.1.1 Maintenance Schedule

The cleanliness of the measurement window is very important to maintain accurate readings.

Calibrate the sensor (if required by the competent authority) according to the maintenance schedule required by the competent authority

6.1.2 Maintenance Methods

• Sensor outer surface: Clean the outer surface of the sensor with tap water. If there is still debris left, wipe it with a soft, damp cloth. For some stubborn dirt, add some household washing liquid to the tap water to clean it.
• Check the cable of the sensor: the cable should not be tightened during normal operation. Otherwise, the internal cable of the cable may be broken and the sensor may not work normally.
• lCheck the sensor's measurement window for dirt.

6.1.3 Precautions
The probe contains sensitive optical and electronic components. Make sure the probe is not subject to severe mechanical shock. There are no parts inside the probe that require user maintenance.

6.2 Sensor Calibration

a) Zero calibration: Take a proper amount of distilled water in a large bucket and place the sensor vertically in the solution. The front end of the sensor is at least 20 cm away from the bottom of the beaker. After 3 to 5 minutes, the value is stabilized and the zero point is calibrated. The instructions refer to the appendix.
b) Slope calibration: Place the sensor probe in the standard solution. The front end of the sensor is at least 20cm away from the bottom of the beaker. After 3 to 5 minutes, the slope is calibrated after the value is stable. The instructions refer to the appendix.
