Industrial Applications

1. Non-contact Level Detection in Small Tanks

This sensor can precisely monitor the fill level of liquids, granules, or bulk materials in compact tanks, hoppers, or containers.

Problem Solved

Its 30-300 mm sensing range and non-contact ultrasonic principle enable accurate level measurement without physical contact, preventing sensor contamination or corrosion from aggressive media. The IP67 rating ensures reliable operation in wet or dusty environments.

2. Object Presence and Position Detection on Conveyor Belts

The sensor reliably detects the presence and precise position of objects on conveyor systems, particularly effective for materials that are transparent, irregularly shaped, or have varying surface textures.

Problem Solved

Ultrasonic technology is unaffected by color, transparency, or surface properties, overcoming limitations of optical sensors. The 10-30 VDC operating voltage is standard for industrial automation, and the PNP NO/NC output seamlessly integrates with control systems. Its compact M18 size facilitates easy installation in confined spaces.

3. Loop Control in Web and Material Processing

Used to maintain a consistent sag or loop of material (e.g., film, fabric, paper, wire) between processing stations to prevent tension fluctuations, breakage, or material jams.

Problem Solved

The sensor's adjustable sensing range of 30-300 mm and programmable switching points allow for precise detection when the material loop deviates from desired limits. Integrated temperature compensation ensures consistent and stable performance despite ambient temperature changes in manufacturing environments.
