Online self-cleaning sludge concentration analyzer, suspended solids sludge concentration sensor
Online self-cleaning sludge concentration analyzer, suspended solids sludge concentration sensor
Product details
Measurement principle of sludge concentration/suspended solids:
The online suspended solids/sludge concentration sensor is based on the combined infrared absorption scattering light method. The infrared light emitted by the light source is scattered by the suspended particles in the sample, and finally converted into an electrical signal by the photodetector. After analog and digital signal processing, the suspended solids/sludge concentration of the sample is obtained.
Functional characteristics of sludge concentration analyzer：
- The sensor adopts dual beam infrared scattering photometry detection technology, which has good repeatability and stability;
- The application of ISO7027 standard method (infrared light scattering technology) can eliminate the influence of sample color;
- Built in self diagnosis function to ensure accurate data;
- Optional cleaning brush with automatic cleaning function, greatly reducing sensor maintenance;
- Digital sensors with strong anti-interference ability and long transmission distance;
- Standard digital signal output, which can be integrated and networked with other devices without a transmitter;
- The on-site installation of sensors is convenient and fast, achieving plug and play functionality;
- Reverse polarity protection for sensor power supply;
- Sensor RS485 A/B terminal misconnected power protection;
- Online monitoring of suspended solids/sludge concentration in various processes of sewage treatment plants;
- Online monitoring of suspended solids/sludge concentration in various industrial production processes, including water and wastewater treatment processes.
