online sludge concentration detector
measuring principle
The sludge concentration sensor is based on the infrared scattering light technology, that is, the infrared light emitted by the light source will scatter through the measured sample during the transmission process, and the intensity of the scattered light is directly proportional to the concentration of the suspended matter. The suspended matter / sludge concentration sensor has a scattered light receiver in the 140° direction, and then the suspended matter concentration value is obtained by analyzing the intensity of this group of scattered light.
functional characteristics
Infrared scattering light technology, can eliminate the influence of sample color;
Optional cleaning brush automatic cleaning function, greatly reduce the sensor maintenance;
Digital sensor, strong anti-interference ability, the transmission distance is long;
Standard digital signal output, enabling integration and networking with other devices without a controller
Sensor site installation is convenient and fast, to achieve plug and play.
Simple use, reliable results, interface operation instructions can reduce operation errors;
Set up a visual alarm system to provide important alarm functions;
The controller can achieve wall mounting / panel mounting / clip mounting.
Sensor power supply positive and negative electrode reverse connection protection
Sensor RS485 A / B terminal with wrong power protection
Typical application
Online monitoring of the sludge concentration in each process of the sewage treatment plant;
Online monitoring of suspended matter (sludge concentration) in the water use and wastewater treatment process of various industrial production process.
