Industrial Applications

1. Precise Level Detection in Small to Medium Liquid Tanks

Utilizing its 70-1000 mm sensing range and non-contact operation, the sensor accurately monitors liquid levels in small to medium-sized tanks, preventing overflows or dry-runs. The enhanced temperature compensation ensures measurement stability even with temperature fluctuations in the liquid or ambient environment, while IO-Link provides real-time diagnostic data and seamless integration into process control systems.

Problem Solved

Inaccurate liquid level monitoring in tanks due to temperature variations or limited integration options, leading to production inefficiencies or material loss.

2. Object Presence and Positioning on Conveyor Systems

The UC1000-18GS-2EP-IO-V15 is ideal for detecting and precise positioning of objects on conveyor belts, regardless of color or transparency, within its 70-1000 mm range. Its selectable sound lobe width allows adaptation to various object sizes and shapes, and the two push-pull outputs provide flexible switching signals. Synchronization capabilities prevent cross-talk when multiple sensors are used in close proximity.

Problem Solved

Unreliable object detection or positioning on production lines, especially with diverse material types or in multi-sensor setups, causing misalignments or stoppages.

3. Continuous Roll Diameter Monitoring in Web Processing

This ultrasonic sensor accurately measures the diminishing diameter of material rolls (e.g., paper, film, textiles) in continuous web processing applications. The sensor's rapid response delay (28 ms min) and stable measurement acquisition after 2 minutes of power-on (due to enhanced temperature compensation) enable real-time monitoring. This allows for timely material replenishment, maintaining consistent production flow and minimizing downtime.

Problem Solved

Inconsistent material supply or unexpected line stoppages in web processing due to inaccurate or delayed monitoring of dwindling material roll diameters.
