How to Measure Level in Stainless Steel Direct-Drink Machine Tanks? Non-Contact Capacitive Level Sensor with Insulation Adapter

School direct-drink machines often use stainless steel inner tanks. Metal walls would short-circuit direct capacitive electrodes. Traditional solutions drill holes for float switches, breaking seals. Xingkechuang's non-contact solution adds an insulation pad on the outer wall. The capacitive principle couples through the insulation and stainless wall to the internal water level — the εr difference produces a strong signal. Shenzhen Xingkechuang Technology Co., Ltd. provides custom insulation kits, helping school bids meet sanitation compliance directly.
