False Alarms from Spoiled Milk in Coffee Machine? Non-Contact Capacitive Level Sensor Avoids Milk Contact

Automatic milk frothers store fresh milk. Contact electrodes immersed in milk develop milk scale and raise hygiene concerns about trace metal ion leaching. Optical windows fog with milk mist, falsely reading "milk present" and dry-pumping.

Xingkechuang non-contact capacitive level sensor sticks to the milk tank outer wall. The capacitive principle utilizes the fact that milk's εr is still far higher than air. Only when real milk level crosses the line does the output flip. Milk scale film and condensation do not trigger false alarms. Shenzhen Xingkechuang Technology Co., Ltd. offers food-grade housing customization, making hygiene audits for milk-coffee machines smoother.
