High Precision & Rapid Response Detection
Equipped with high-sensitivity infrared optical chip, it realizes real-time and accurate identification of water level empty, low and full status. With ultra-fast signal response, it effectively supports automatic water supply, overflow prevention and water shortage protection for water treatment equipment, ensuring stable system operation.
Strong Anti-Fouling & Environmental Adaptability
Optimized smooth probe structure resists sludge, algae and impurity adhesion in sewage and reclaimed water scenarios. It features strong anti-electromagnetic interference capability and wide temperature adaptability, suitable for long-term continuous operation in various harsh water treatment and environmental protection working conditions.
Working Principle
⚙️ Working Principle
Based on the differences in total internal reflection and refraction of infrared light between air and water media, it achieves precise liquid level state switching:
🔦 Stable Light Emission: The built-in infrared LED continuously emits a stable light signal to the precision prism probe.
☁️ In Air (Total Internal Reflection): When the probe is not in contact with water, the infrared light undergoes total internal reflection inside the prism. It is normally received by the photoelectric receiver, outputting a fixed electrical signal.
💧 Submerged in Water (Refraction): As the water level rises and covers the probe, the refractive index of the external medium changes, breaking the total reflection condition. Most of the light refracts into the water, preventing the receiver from capturing a valid signal.
📶 Signal Switching & Control: Once the system detects the change in the optical signal, it instantly converts it into a standard digital signal to trigger a state flip, enabling real-time water level monitoring and precise automation control.
