Suspended solids sensor is an instrument used to detect the concentration or content of suspended particles (such as solid particles, colloids, algae, etc.) in liquids, and is widely used in water quality monitoring, environmental governance, industrial process control, and other fields. Its core function is to convert the physical properties of suspended solids (such as transparency and scattering) into electrical signals through specific detection principles, thereby achieving quantitative analysis of suspended solids concentration.
Suspended solids sensors are mainly used for real-time monitoring of suspended solids concentration in water, achieving water quality monitoring by measuring the scattering of light by suspended solids or changes in electrode potential. Its core functions include:
Water quality monitoring: widely used in the fields of drinking water treatment, industrial wastewater treatment, and environmental monitoring, providing data support for optimizing water treatment processes.
Anti interference design: using infrared scattered light technology, not affected by water sample color interference, ensuring measurement stability.
Intelligent features: Supports self-cleaning function, reduces maintenance requirements; Equipped with a visual alarm system that triggers an alarm when exceeding the standard.
Suspended solids sensors typically consist of the following components:
Detection unit: including light source (such as LED, laser diode), receiver (photodiode, ultrasonic probe), responsible for transmitting signals and receiving signals affected by suspended solids.
Signal processing unit: converts the raw signals of the receiver (light intensity, sound intensity, etc.) into electrical signals (voltage, current), and calculates the concentration of suspended solids through algorithms.
Output unit: Output the detection results as analog signals, digital signals, or display screens for easy data transmission or reading.
Protective shell: mostly made of stainless steel or corrosion-resistant materials, it protects internal components from liquid corrosion and is suitable for underwater or harsh environments (such as industrial pipelines).
Suspended solids sensors achieve real-time monitoring of particulate matter in liquids through principles such as optics and ultrasound, and are important tools for water quality management, industrial production, and environmental governance. When selecting, it is necessary to consider the detection scenario, accuracy requirements, and environmental characteristics, and pay attention to maintenance and calibration during use to ensure data reliability. With the development of IoT technology, some suspended object sensors have wireless transmission capabilities and can be connected to monitoring platforms for remote monitoring, further improving application efficiency.
