Description

The XKC-Y26 sensor utilizes advanced capacitive sensing and signal processing technology to detect liquid levels from outside a non-metallic container. This non-invasive method eliminates the need for direct contact with the liquid, preventing contamination, corrosion, or scaling issues, making it ideal for monitoring aggressive or sterile fluids.

Featuring an ABS plastic housing, the sensor is designed for reliable operation in environments with 5-100% relative humidity. Its intelligent circuitry ensures stable performance and high sensitivity, unaffected by container wall thickness, enabling deployment in high-pressure or sealed systems without drilling or modification.

Key Features

  • Intelligent non-contact capacitive sensing principle
  • Compatible with a wide range of liquids, including acids, alkalis, and toxic substances
  • High stability and sensitivity for precise level detection
  • Durable ABS plastic construction for general-purpose use
  • Easy external installation under or on the side of containers
  • Optimized performance-to-cost ratio for automated liquid management
  • Low power consumption suitable for battery-backed or always-on systems

Applications

  • Water level monitoring in residential water towers and storage tanks
  • Liquid level detection in chemical processing and sewage treatment tanks
  • Irrigation system reservoir management for drones and agricultural automation
  • Fluid level sensing in medical equipment and laboratory analyzers
  • Aquarium and hydroponic system water level control

Frequently Asked Questions

What is the operating voltage range for the XKC-Y26 sensor?

The XKC-Y26 operates from a 5 to 12 VDC power supply. It is compatible with common 5V microcontroller systems (Arduino, Raspberry Pi) and standard 12V industrial or automotive power rails. Ensure your power source can provide the low 5mA current draw.

How do I wire the NPN output to my Arduino or PLC?

The NPN output is an open-collector (sinking) transistor. Connect the sensor's output wire to your digital input pin. Connect a pull-up resistor (e.g., 10kΩ) from that input pin to your system's positive voltage (5V or 3.3V). The output will pull the line LOW (to GND) when liquid is detected.

Can this sensor detect liquid through any container material?

No, it is designed specifically for non-metallic containers such as plastic, glass, or ceramic. The capacitive sensing principle is blocked by conductive metals. The container wall thickness can vary, but the material must be a non-conductive dielectric for reliable operation.

What is the response time and how does it affect system design?

The sensor has a 500ms (0.5 second) response time. This is suitable for monitoring tank levels, irrigation systems, and appliance controls where state changes are not instantaneous. For applications requiring rapid, real-time detection of fast fluid movement, a faster sensor may be required.
