The XKC-Y28A is an advanced non-contact liquid level sensor designed specifically for small-diameter non-metallic pipes. Manufactured by XINGKECHUANG, a leading provider of industrial sensing solutions, this innovative sensor detects liquid presence from outside the pipe without direct contact with the medium. This unique design eliminates contamination risks, prevents corrosion, and ensures reliable operation even with strong acids, alkalis, and liquids containing scale or impurities.
Available in three output configurations—normally open (NO), normally closed (NC), and RS485 communication—the XKC-Y28A offers exceptional versatility for system integrators and equipment manufacturers. With its compact form factor, IP67 waterproof rating, and wide operating temperature range of -20-105℃, this sensor delivers consistent performance in the most demanding industrial and medical environments.
Model: XKC-Y28A-NO (DC 5V), (DC 12V), (DC 24V) — Normally Open Output
Model: XKC-Y28A-NC (DC 5V), (DC 12V), (DC 24V) — Normally Closed Output
Model: XKC-Y28A-RS485 (DC 24V) (DC 5V-12V) — RS485 Communication Output
The XKC-Y28A operates on advanced capacitive sensing technology that penetrates non-metallic pipe walls to detect liquid levels internally. This non-invasive approach means the sensor never comes into contact with the liquid being monitored, making it ideal for applications involving corrosive chemicals, sterile solutions, or sensitive biological fluids. Unlike traditional immersion sensors, there is no risk of sensor degradation, pipe leakage, or cross-contamination between batches.
Featuring an innovative clip-on design, the XKC-Y28A can be installed in seconds without any special tools, drilling, or pipe modification. Simply snap the sensor onto the outside of the pipe at the desired monitoring point. This not only reduces installation time and labor costs but also allows for easy repositioning or removal as system requirements change. The sensor is compatible with non-metallic pipes with an outer diameter of 5-10mm.
Unlike many competing sensors that require external relays, the XKC-Y28A integrates a 2A relay directly into its compact housing. This allows the sensor to directly drive small loads such as pumps, valves, and alarms without additional components. This integrated design simplifies system wiring, reduces overall system cost, and improves reliability by eliminating potential points of failure.
The XKC-Y28A series offers multiple power supply options including DC 5V, 12V, and 24V to accommodate a wide range of system requirements. Three output modes are available: normally open (NO), normally closed (NC), and RS485 communication. The RS485 model supports Modbus protocol, enabling seamless integration into industrial control systems and remote monitoring applications.
The XKC-Y28A is widely used in intravenous infusion pumps and medical fluid delivery systems to monitor liquid levels and detect empty conditions. Its non-contact design ensures complete sterility and eliminates the risk of cross-contamination between patients.
In pharmaceutical production, the sensor monitors liquid levels in processing tanks, transfer lines, and filling machines. It is particularly valuable for handling corrosive chemicals and sterile solutions where contamination must be strictly avoided.
Laboratory equipment manufacturers rely on the XKC-Y28A for precise liquid level detection in analytical instruments, chromatography systems, and bioreactors. Its high accuracy and reliability ensure consistent experimental results.
The sensor is also used in various industrial applications involving small-diameter tubing, including inkjet printers, beverage dispensing equipment, and chemical processing systems.
The XKC-Y28A is designed for non-metallic pipes with an outer diameter of 5-10mm. It works with all common non-metallic materials including PVC, PP, PE, and glass.
The XKC-Y28A can detect most conductive and non-conductive liquids including water, oils, chemicals, and pharmaceutical solutions. It is not affected by color, transparency, or the presence of suspended particles.
The sensor has a fast response time of 500mS, ensuring timely detection of liquid level changes and preventing overflow or dry-run conditions.
Yes, the XKC-Y28A features an IP67 waterproof rating, making it fully protected against dust and immersion in water up to 1 meter for 30 minutes. It can be used in humid, wet, or even outdoor environments.
The XKC-Y28A is available in three output configurations: normally open (NO), normally closed (NC), and RS485 communication. The RS485 model supports Modbus RTU protocol for integration into industrial control systems.
