Introduction
Principle & Structure
The turbidity sensor is based on the combined infrared absorption and scattered light method. The infrared light emitted by the light source is scattered by the turbidity in the sample, and finally converted into an electrical signal by a photodetector, and the turbidity value of the sample is obtained after analog and digital signal processing.
Features
● The sensor adopts double beam infrared scattering photometer detection technology to achieve better repeatability and stability;
● The application of ISO7027 infrared light scattering technology can effectively eliminate the influence of sample color;
● Built-in self-diagnosis function to ensure accurate data;
● Optional cleaning brush automatic cleaning function, greatly reducing the amount of sensor maintenance;
● Digital sensor, strong anti-interference ability, long transmission distance;
● Standard digital signal output, which can realize integration and networking with other equipment without transmitter;
● The on-site installation of the sensor is convenient and fast, realizing plug and play;
● The use is simple, the results are reliable, and the interface operation instructions can reduce operation errors;
● A visual alarm system is set up to provide important alarm functions;
● The controller can be wall mounted/panel mounted/pipe mounted.
application
