The XKC-Y25 capacitive non-contact liquid level sensor is a reliable and intelligent solution for detecting liquid levels without direct contact with the liquid. Based on capacitive sensing technology, this sensor detects changes in capacitance through non-metallic container walls, making it ideal for sealed tanks, pipes, and containers. The XKC-Y25-NPN variant is widely used in automation, water management, and industrial control systems in Bangladesh due to its stability, easy installation, and compatibility with multiple output types.
