Measuring principle and application occasions of online suspended solids detector

by:BOQU     2023-04-10
The online suspended solids detector is a variety of maintenance-free analyzers specially provided for water treatment, and there are a variety of probes, transmitters, mounting brackets, or integrated analyzers to choose from. Measuring principle of the online suspended matter detector: The infrared light sent by the transmitter of the detector is absorbed, reflected and scattered by the measured object during transmission, and only a small part of the light can irradiate the receiver. The concentration of impurities in the measured medium is proportional, and the concentration of impurities can be calculated by measuring the transmittance of transmitted light. The instrument adopts the four-beam measurement principle, using two emitters and two monitors to obtain a series of optical paths, form a measurement matrix, and convert the measurement results. Multi-optical measurement eliminates interference, compensates for contamination, and allows measurements in harsh environments. At the same time, it has a flushing port, which can choose manual or automatic cleaning of the attachment on the sensor. The suspended solids detector adopts unique algorithm software to make the instrument suitable for various occasions; high precision and stability, strong anti-interference ability; simple on-site calibration; built-in automatic temperature compensation; high-brightness liquid crystal display concentration percentage, mg/l and Graphics; 4-20mA output, RS232 or 485 digital output interface, liquid level alarm and fault alarm relay output; the protection level of the transmitter and sensor shell reaches IP65 and IP68 respectively, and can be replaced according to the special requirements of the application. Examples of applications for suspended matter detectors: 1. Urban sewage treatment plants Sludge control in primary and secondary sedimentation tanks. Sludge thickening tank; automatic control of sludge dehydration and chemical dosing; return sludge concentration monitoring. 2. Water supply plant Automatic monitoring of sludge height in sedimentation tanks; automatic sludge discharge control in sedimentation tanks. 3. Industrial wastewater treatment Sludge concentration monitoring ore slurry and industrial slurry concentration monitoring. 4. Natural water body Monitoring of sediment concentration in rivers.
