Users of water purifiers often encounter level detection false alarms. The root cause usually lies in optical sensor lenses being covered by scale or algae, or float balls getting stuck by impurities. In contrast, the working principle of capacitive non-contact liquid level sensors does not rely on light refraction or mechanical movement.
The XKC series sensors from Shenzhen Xingkechuang Technology Co., Ltd. feature built-in intelligent filtering algorithms. They use threshold discrimination to distinguish between "actual liquid level" and "inner wall condensation water film / thin layer scale." Since only a significant capacitance change caused by a large volume of water triggers the alarm, minor attachments are filtered out by the algorithm.
In the complex environment of water purifier tanks where hot and cold water cycles cause condensation, the Xingkechuang sensors detecting by adhering to the outer wall remain stable. This helps OEMs reduce after-sales repair rates and improve brand reputation.
