The Keyence FU-95H Liquid-Level Detection Fiber Unit is a specialized optical fiber sensor designed for precise monitoring of liquid presence within transparent tubing. It offers high versatility and reliability, making it suitable for a wide range of applications in industrial automation, fluid handling systems, laboratory instrumentation, and quality assurance environments. By combining compact dimensions with a robust design, the FU-95H delivers accurate and stable liquid detection even in constrained or challenging setups.

One of the standout advantages of the FU-95H is its wide tube compatibility, accommodating transparent tube diameters from 4 mm to 26 mm. This flexibility makes it useful across industries where different tubing sizes are common, such as chemical processing, semiconductor equipment, food and beverage manufacturing, or pharmaceutical production. By supporting such a broad range, the unit minimizes the need for multiple fiber models, simplifying installation and reducing equipment variety.

The fiber unit construction is both practical and adaptable. With a length of 2 meters, the FU-95H provides sufficient reach for installations that require extended routing, while the free-cut capability allows users to trim the fiber to exact lengths for optimized setup. The slim √∏1.0 √ó 2 mm profile makes it easy to integrate into compact equipment, ensuring minimal intrusion into existing layouts. Furthermore, its minimum bend radius of R10 mm enhances installation flexibility, permitting routing through narrow spaces or around tight corners without risk of signal loss or performance degradation.

Functionally, the FU-95H excels at reliable liquid-level detection. The fiber unit works by transmitting light through transparent tubing and identifying changes caused by the presence or absence of liquid. This optical principle enables highly accurate detection that is not affected by tube color or fluid type, provided the tube is transparent. The result is consistent monitoring performance, which is essential for processes requiring precise fluid control—such as automated filling, leak detection, or ensuring proper fluid flow in delicate production systems.

The design also contributes to long-term durability. The fiber construction resists bending stress and can endure frequent movement or handling, making it reliable in dynamic industrial environments. Additionally, the optical sensing method eliminates direct contact with the liquid, preventing sensor contamination and reducing maintenance requirements compared to conventional level-detection methods.

In summary, the Keyence FU-95H is an efficient, compact, and versatile fiber unit built specifically for liquid-level detection in transparent tubing. With its broad mounting range, flexible fiber design, and dependable detection performance, it is ideally suited for industries requiring accurate fluid monitoring and stable automation control. Whether used in high-tech manufacturing, chemical handling, or laboratory applications, the FU-95H ensures dependable operation with minimal setup challenges.
