SingoCreate Tech's non-contact capacitive liquid level sensor is based on advanced electric field induction technology. Its working principle is as follows:

Core Technical Principle:

The sensor probe and the container wall form one plate of a capacitor, with the container wall and the liquid acting as the dielectric. When the liquid level changes, the system's capacitance value changes accordingly. A precision detection circuit accurately captures this minute change, and an intelligent algorithm precisely judges the liquid level status.

Advantages Compared to Traditional Technologies:

Technical Indicator	Float Type	Photoelectric Type	SingoCreate Capacitive Type
Contact Contamination	Direct contact, high risk	Direct contact, medium risk	Complete isolation, zero risk
Reliability	Mechanical structure prone to jamming	Optical window prone to fouling	No moving parts, long life
Accuracy	Low accuracy, affected by density	Greatly affected by color, bubbles	High accuracy, fewer affecting factors
Installation/Maintenance	Complex installation, frequent maintenance	Optical window cleaning required	Simple installation, maintenance-free
Cost	Low unit cost, high total cost	Medium unit cost, medium maintenance	Medium unit cost, low total cost

Unique Technical Advantages:

•
Automatic Temperature Compensation: Built-in temperature sensor automatically compensates for temperature change effects.
•
Adaptive Calibration: Intelligent algorithm adapts to different container materials and wall thicknesses.
•
Multiple Safety Protections: Short circuit, reverse connection, and overload protection ensure device safety.

Conclusion

Technological innovation is the core driving force for the advancement of medical devices. Through continuous R&D, Shenzhen SingoCreate Technology Co., Ltd. constantly breaks through technical bottlenecks, providing the medical industry with more advanced and reliable liquid level detection solutions.
