In precision manufacturing like unwinding separators for lithium battery cells, traditional sensors often fail due to inadequate accuracy, signal interference from materials, or inability to adapt to dynamic changes. Inaccurate roll material remaining calculations can directly lead to premature material changes causing waste or major losses from material shortages and production stoppages.

01 Precision Revolution: Entering the Micrometer Era

Modern industrial inspection demands precision at the micrometer level. The introduction of Fuwei Electronics' FSD26 series laser displacement sensors marks a significant breakthrough in non-contact measurement technology.

Employing a precision optical system and unique algorithms, this sensor effectively suppresses ambient light interference to achieve stable detection of minute objects with micrometer-level repeatability. Its linear accuracy reaches ±0.1% F.S., maintaining data precision across the entire 26mm to 294.98mm measurement range.

Compared to traditional ultrasonic sensors with repeatability accuracy of only 1-2mm, the FSD26 delivers nearly tenfold improvement in precision. This enables it to capture minute changes undetectable by conventional equipment, providing a reliable data foundation for quality control.

02 Dynamic Capture: 3000 Measurements per Second for Ultimate Responsiveness

On modern high-speed production lines, measurement speed directly determines production efficiency. With a sampling frequency of up to 3KHz, the FSD26 series ushers laser displacement measurement into the millisecond-response era.

This enables the sensor to perform 3000 precise measurements per second—sufficient to capture instantaneous displacement changes of fast-moving targets. Whether tracking the trajectory of a rapidly moving dispensing head or capturing the instantaneous posture of a robotic arm during high-speed grasping, the FSD26 delivers a continuous, stable, and high-fidelity data stream.

This ultra-fast measurement capability enables real-time monitoring and instantaneous adjustments on production lines, preventing production disruptions caused by data lag. It serves as a reliable “sensory nerve ending” for high-speed dynamic processes.

03 Universal Material Compatibility, Eliminating Calibration Hassles

Traditional laser sensors often require cumbersome parameter adjustments when encountering different material surfaces, severely impacting production efficiency. The FSD26 series resolves this industry pain point through technological innovation.

This sensor achieves stable measurements on diverse surfaces including metal, plastic, and ceramics. In mixed-flow production environments, the FSD26 excels—requiring only a single installation to adapt to measurement demands across varied material workpieces.

This robust material compatibility means production line operators can bid farewell to repetitive debugging, achieving true “plug-and-play” functionality. This significantly enhances production line flexibility and changeover efficiency.

04 Rugged Design, Unfazed by Harsh Environments

Industrial environments are complex, with factors like vibration, temperature fluctuations, and electromagnetic interference potentially affecting measurement device stability. The FSD26 series offers comprehensive optimization for these challenges.

As the final batch of inspection equipment equipped with FSD26 sensors rolls off the production line and into shipping crates, destined for smart factories across the nation, the boundaries of perception precision in modern manufacturing are once again pushed forward.
