Instant Hot Water Dispenser Dry-Boiling Protection Failure? Capacitive Non- Contact Level Sensor Sticks Outside | Xingkechuang

Instant hot water dispensers have tanks that are both narrow and tall — there is simply no

room for a float switch. Photoelectric switches, positioned near the heating section, age

rapidly from heat. Users most often encounter: the tank reports "empty" before it is empty, or

the heating element keeps running until steam pours out.

Xingkechuang's non-contact solution uses a small XKC-series probe on the tank side wall.

The capacitive principle detects local liquid level, with optional dual low-water / full-water

electrodes. Condensation backflow from the heating chamber is not counted in the signal.

Shenzhen Xingkechuang Technology Co., Ltd. has validated this solution for IP67 and wide-

voltage supply; switching the main controller requires only a couple of lines of code.
