The water tank is the heart of a dispenser, and its "eyes" are the water tank level sensor. The right choice directly impacts performance and reliability. Shenzhen StarCore Technology Co., Ltd., a specialist sensor provider, outlines the key selection criteria.4 Core Selection Factors:
Sensing Principle & Mounting: Float switches require tank penetration and can jam; optical sensors fear scale. StarCore's non-contact capacitive sensors mount externally—no holes, no contamination, easy installation.
Tank Material & Wall Thickness: Capacitive sensors work through non-metals. Specify your material (e.g., PP, ABS) and wall thickness. StarCore engineers recommend the optimal sensitivity model for stable detection.
Output Signal Need: Choose digital switch outputs (for low/high alarms) or analog/PWM signals (for continuous display) based on your control logic. StarCore offers a complete product range.
Long-Term Reliability & Certifications: Dispensers demand high lifespan and safety. StarCore sensors have no mechanical wear, resist corrosion, and outlast the appliance, meeting all relevant safety standards.
Conclusion: For modern dispensers, the non-contact capacitive water tank level sensor is the optimal solution balancing safety, reliability, intelligence, and aesthetics. Shenzhen StarCore Tech provides full-cycle support from selection to volume delivery.
