Ultrasonic Rectangular Transducer for Web Fabric Correction and Through-beam Edge Position Tracking and Guiding Detection
This waterproof, sealed, integrated ultrasonic probe is suitable for web fabric correction and edge positioning, offering both high sensitivity and stable detection performance.
This integrated ultrasonic probe combines transmission and reception capabilities into a compact, sealed unit. Its waterproof construction makes it an ideal solution for complex industrial environments where moisture or dust might be present. Unlike optical sensors, this Ultrasonic Web Guiding Sensor is unaffected by the transparency of the material, making it perfect for clear films, opaque foils, and breathable fabrics.
Key advantages include a wide bandwidth, high sensitivity, and an excellent signal-to-noise ratio. These features ensure reliable non-contact distance measurement and edge positioning, significantly reducing material waste and improving production efficiency.

Typical Applications
Rectangular Sensing Precision: The New Standard in Web Guiding Designed with a specialized rectangular sensing face (28x18mm), this 160kHz high-frequency ultrasonic sensor outperforms traditional circular probes in stability and range. The unique rectangular geometry provides a larger effective detection area, ensuring smooth, jitter-free edge tracking even when handling mesh materials, uneven edges, or vibrating webs. It is the ultimate solution for transparent film correcting, impervious to dust and light. Beyond packaging, its high precision makes it ideal for the Lithium Battery industry, specifically for the edge alignment of metal electrode sheets, as well as rubber, wood, and non-woven fabric processing.
