Industrial Applications

1. Non-contact Liquid Level Monitoring in Tanks

The UB500-30GM-E5-V15 precisely monitors liquid levels in small to medium-sized tanks, preventing overfilling or running dry. Its 30-500mm sensing range accommodates various tank sizes, and the IP65 rating ensures durability in wet environments. The programmable PNP output can reliably trigger pumps or alarms based on set liquid levels, enhancing process automation.

Problem Solved

Accurately and reliably monitors liquid levels without physical contact, avoiding contamination or damage from corrosive liquids, and automating fill/drain processes in industrial settings.

2. Object Detection and Positioning on Conveyor Belts

This sensor can reliably detect the presence and precise position of objects, regardless of their color, transparency, or material composition, on a conveyor belt system. Its 30-500mm range allows flexible mounting above the belt, and the 10 Hz switching frequency ensures consistent detection of objects moving at moderate speeds, facilitating automated sorting or handling.

Problem Solved

Provides reliable detection of diverse objects, overcoming limitations of optical sensors with transparent or highly reflective materials, ensuring proper material flow and robotic handling on production lines.
