Industrial Applications

1. Conveyor Belt Material Detection

Utilizing the sensor's background suppression (BGS) technology and 0-1250mm detection range to accurately differentiate various materials or products on a conveyor belt, regardless of their color or the background surface.

Problem Solved

Inconsistent detection of objects with varying colors or textures against a static or reflective conveyor background, leading to mis-sorts or production line stoppages.

3. Non-Contact Liquid Level Monitoring in Bottling Plants

Implementing the sensor for non-contact liquid level detection in opaque or semi-transparent bottles during filling processes, where the modulated visible red light and BGS ensure accurate sensing without physical contact.

Problem Solved

Traditional contact sensors causing contamination risks or being unsuitable for high-speed bottling lines, leading to inconsistent fill levels and product waste.
