When selecting a level detection scheme for water purifiers, R&D teams often weigh options between float switches, photoelectric sensors, and capacitive types. Traditional float switches have mechanical contacts that easily get stuck due to limescale over time, leading to "dry burning" or "overflow." While photoelectric sensors have no moving parts, their infrared lenses are highly susceptible to blocking by scale or bubbles.
Shenzhen Xingkechuang Technology advocates for the Capacitive Non-contact Level Detection Principle, which avoids these defects physically. It has no moving parts, is unaffected by scale coverage (the sensing surface is insulated), and uses changes in dielectric constant to judge water levels, intelligently filtering out attached water droplets. For water purifier manufacturers focused on quality and after-sales reputation, adopting Xingkechuang Tech’s highly reliable non-contact capacitive sensors can significantly reduce the overall failure rate and build user trust.
