Industrial Applications

1. Level Monitoring in Non-Transparent Tanks

This sensor is ideal for continuously monitoring the fill level of liquids or bulk materials in tanks, silos, or hoppers, especially for substances that are opaque or have varying colors, where optical sensors would fail.

Problem Solved

Provides precise, continuous analog feedback (0-10V) of fill level (0.35mm resolution, ±0.1% accuracy) over a range of up to 1 meter. Its ultrasonic principle is unaffected by material color or transparency, making it suitable for diverse media. The IP65 rating ensures durability in typical industrial tank environments, and temperature compensation maintains accuracy across ambient temperature fluctuations (-25 to 70°C).

2. Web Tension/Sag Control in Material Handling

The sensor can be used to precisely measure the sag or tension of a continuous web of material (e.g., paper, fabric, plastic film) in converting or packaging machinery, providing feedback for loop control.

Problem Solved

The accurate distance measurement with 0.35mm resolution and 0-10V analog output allows for fine control of web position or sag, crucial for maintaining consistent tension and preventing material breakage or creasing. Its non-contact nature prevents damage to delicate materials, and the 70-1000mm range is suitable for typical web paths.

3. Object Positioning and Sorting on Conveyor Systems

Implement precise object detection and positioning on conveyor belts, enabling accurate sorting, indexing, or robotic pick-and-place operations, especially for objects with irregular shapes, varied colors, or challenging surfaces.

Problem Solved

The sensor's ability to detect objects within its 70-1000mm range, irrespective of color or transparency, combined with high resolution and repeat accuracy, ensures reliable object detection and precise positioning for automated sorting or handling tasks. The M18 cylindrical form factor allows for easy integration into conveyor lines, and the IP65 rating protects against dust and splashes.
