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:
