Online turbidity sensor

one.How Online turbidity sensor works

Online turbidity sensor is a device that measures the degree to which water loses transparency due to the presence of suspended particles using the light scattering method.Online turbidity sensor determines the concentration of particles in the liquid by measuring the scattering of light.It uses a light source to shine into the liquid and then measures the intensity of the scattered light at different angles.This sensor uses 90° angle scattering method to linearly process the acquisition value, and outputs the turbidity value through a temperature compensation algorithm.

The cable is a 5-core shielded wire:

Red line - power line black line - ground line green line - 485A white line - 485B

3.Online turbidity sensor installation

Note: The sensor cannot be installed inverted or horizontally when installed, and should be installed at least 15 degrees above the angle of inclination.The test port will not touch the container wall within 5CM left and right, and 10CM below

Four.Online turbidity sensor maintenance and maintenance

Sensor maintenance:

If the sensor needs to be cleaned, you can use warm water and an appropriate amount of detergent to clean it.

Notice:

Avoid strong vibration damage to the front of the transparent glass, and do not scratch with hard products.

five.Online turbidity sensor user calibration

The sensor has been carefully calibrated when it leaves the factory, and generally does not require user calibration.If the user calibration is performed, you can execute the instructions to restore the factory.

5.1 Zero Point Calibration

Place the sensor in a non-transparent container, and use distilled water or pure water to ensure that the sensor's test port will not touch the container wall within 5CM on the left and right, and 10CM below.After the value stabilizes for 30 seconds, perform zero-point calibration according to the communication instructions.

5.2 Slope calibration

Place the sensor in a non-transparent container, and use a solution with a known turbidity (the turbidity value must be greater than 20% range) to ensure that the sensor's test port will not touch the container wall within 5CM on the left and right, and 10CM below.After the value stabilizes for 30 seconds, the slope calibration will be performed according to the communication instructions.
