Industrial Applications

1. Liquid Level Detection in Non-Metallic Tanks

This sensor can accurately detect the presence or absence of various liquids, including water, oils, and chemicals, through the walls of non-metallic tanks or containers. Its adjustable sensing distance from 1 to 8 mm allows for fine-tuning based on tank wall thickness and liquid properties, ensuring reliable level monitoring without direct contact.

Problem Solved

Prevents costly overfilling or dry-running conditions in tanks by providing non-invasive liquid level feedback, eliminating the need for tank wall penetration and ensuring safety with its wide operating voltage (10-30VDC) and robust IP67 rating.

2. Granular Material and Powder Detection in Hoppers

Ideal for monitoring the fill levels of granular materials such as plastic pellets, grains, or powders within hoppers, silos, or chutes in industrial processing and packaging lines. The sensor's ability to detect non-conductive materials and its adjustable sensitivity make it versatile for varying material densities and compositions.

Problem Solved

Ensures continuous material flow and prevents costly production stoppages due to material blockages or low levels. The M18 stainless steel housing and IP67 protection allow it to operate reliably in dusty and potentially abrasive environments.

3. Object Detection on Conveyor Belts in Harsh Environments

Used for reliable presence detection of objects, regardless of their material (plastic, wood, certain metals) or irregular shapes, on conveyor belts within demanding industrial settings. Its non-contact operation and adjustable sensing range make it suitable for diverse material handling tasks.

Problem Solved

Provides accurate object detection for automated sorting, counting, or precise positioning applications. The sensor's IP67 protection and stainless steel housing ensure long-term durability and performance even when exposed to dust, moisture, or light impacts on a production line.
