KNT601 Online Turbidity Sensor
 
1.Working Principle
KNT601 integrated online turbidity sensor is designed and manufactured using the principle of scattered light turbidity measurement. When a beam of light is incident on a water sample, the light is scattered by the turbidity substance in the water sample, and the intensity of the scattered light in the direction perpendicular to the incident light is measured and compared with the internal calibration value to calculate the turbidity in the water sample. Degree, linearized to output the final value.
2.Feature

• 90° angle scattered light principle, built-in temperature sensor
• Support RS-485, Modbus/RTU protocol
• Optical fiber structure, strong resistance to external light interference
• Infrared LED light source with high stability
• IP68 protection, water depth within 20 meters
• Convenient, fast, stable and easy to maintain

Note:The sensor connector is m16-5 core waterproof connector male.

5.Installation and Electrical Connection

5.1 Install

Installation distance requirements: keep above 5 cm with side wall and above 10 cm with bottom.

5.2 Electrical Connection

• Red wire-power cord(12～24 V)
• Black wire-ground wire(GND)
• Blue Line-485 A
• White Line-485 B
• Bare wire-shield line

After the wiring is completed, it should be carefully checked to avoid the wrong connection before the power is turned on.

Cable specification: considering that the cable is immersed in water (including sea water) or exposed to air for a long time, the cable has a certain corrosion resistance. All interfaces of cable outer diameter Φ6mm, have been waterproof.

6.Maintenance

6.1 Maintenance Procedures and Methods

6.1.1 Maintenance Schedule

The cleanliness of the measuring window is very important for maintaining accurate readings.

6.1.2 Maintenance Method

• Sensor outer surface: clean the outer surface of the sensor with tap water, if there is still debris residue, wipe with wet soft cloth, for some stubborn dirt, you can add some household washing liquid to tap water to clean.
• Check the cable of the sensor: the cable should not be tightened when it is working properly, otherwise it is easy to break the wire inside the cable and make the sensor unable to work properly.
• Check the sensor measurement window if there is any dirt, cleaning brush is normal.

6.1.3 Matters Need Attention
The probe contains sensitive optical and electronic components. Make sure the probe is not subjected to severe mechanical impact. There are no components inside the probe that need to be maintained by the user.

6.2 Calibration of Sensors

a) Zero calibration: take proper amount of zero turbidity solution with large beaker, put the sensor vertically in the solution, the front end of the sensor is at least 10 cm from the bottom of the beaker, and the zero calibration will be carried out after the value is stabilized for 3 minutes. The instructions refer to the appendix.

b) Slope calibration: the sensor probe is placed in the standard solution, the front end of the sensor is at least 10 cm from the bottom of the beaker, and the slope calibration is carried out after 3 ≤ 5 minutes of numerical stability. The instructions refer to the appendix.
