Measurement Principle

The turbidity sensor is based on the combined infrared absorption and scattering light method. Infrared light emitted by the light source is scattered by the turbidity in the sample, then converted into an electrical signal by the photoelectric detector. After analog and digital signal processing, the turbidity value of the sample is obtained.

Features

lThe sensor uses dual-beam infrared scattered light photometer detection technology, offering good repeatability and stability;

lApplication of the ISO7027 standard method (infrared light scattering technology) eliminates the influence of sample color;

lBuilt-in self-diagnostic function ensures data accuracy;

lOptional automatic cleaning brush function significantly reduces sensor maintenance;

lDigital sensor with strong anti-interference capability and long transmission distance;

lStandard digital signal output enables integration and networking with other devices without a transmitter;

lEasy and quick on-site installation, plug-and-play;

lSimple to use, reliable results, and interface operation instructions to reduce operational errors;

lEquipped with a visual alarm system providing important warning functions;

lThe controller supports wall mounting/panel mounting/pipeline clamping installation;

lReverse polarity protection for sensor power supply;

lProtection against incorrect wiring of RS485 A/B terminals.

Typical Applications

lOnline turbidity monitoring at water plant inlets, sedimentation tanks, and other stages;

lOnline turbidity monitoring in sewage plants, various industrial process water, and wastewater treatment processes.
