In the field of water purifier level detection, an excellent sensor must balance reliability, durability, safety, and cost optimally. The XKC-Y25 Series Capacitive Liquid Level Sensor launched by Shenzhen Sincotec Technology Co., Ltd. is precisely tailored for the industry based on deep market insight and technical expertise, setting a benchmark.1. Core Product Features
True Non-Contact Detection: The sensing surface is completely isolated from the measured liquid—no contamination, corrosion, or wear—far outlasting mechanical products.
High Precision & Consistency: Utilizes proprietary ASIC chips for high detection accuracy and excellent batch-to-batch consistency, facilitating automated assembly and debugging on production lines.
Superior Environmental Adaptability:
Wide Temperature Range: Operates from -20°C to +85°C, suitable for climates across regions.
High Protection Rating: The sensing head can achieve an IP68 rating, fearless in humid environments.
Strong Anti-Interference: Integrated filtering algorithms effectively suppress electromagnetic interference from motors, inverters, etc.
Food-Grade Safety: Materials in contact with the sensing surface comply with FDA-recognized food-grade standards, ensuring safety and non-toxicity for drinking water equipment.
Extremely Simple Installation: Supports threaded fixation, clip mounting, adhesive bonding, etc. Can be attached to the outer wall of tanks (non-metallic), greatly simplifying structural design.

3. Typical Application & ConnectionIn a water purifier, the XKC-Y25 series sensor typically connects to the main control board. Taking a "Normally Open (NO)" output as an example:
Dry-Running Protection: Sensor installed at the low-level point of the raw water tank. Outputs one state when water is present; flips state when water is absent, triggering shutdown protection by the main board.
Full Tank Shutdown: Sensor installed at the top of the pressure tank. Outputs one state when not full; flips state when full, triggering the main board to close the inlet valve.
Shenzhen Sincotec Technology Co., Ltd. provides detailed application guides and wiring diagrams and supports joint debugging with clients. Every CLLS series sensor is produced on automated lines under strict ISO9001 standards and undergoes rigorous testing including temperature cycling, endurance, and EMC, ensuring a "zero-defect" product for our clients.
