Industrial Applications

1. Automated Conveyor System Object Detection

This sensor can precisely detect the presence and position of various objects on a conveyor belt, even irregularly shaped ones, due to its ultrasonic sensing principle and adjustable sensing range of 30-500 mm. The two programmable PNP outputs allow for flexible control, such as triggering an action upon object detection and signaling a 'no object' condition. The IP67 rating ensures reliable operation in dusty or washdown conveyor environments.

Problem Solved

Prevents product collisions, ensures accurate counting, and controls conveyor stops/starts, even in wet or dirty conditions, by reliably detecting objects within a specific range.

2. Liquid Level Monitoring in Non-Contact Tanks

The UB500-18GM75-E6-V15 is suitable for non-contact liquid level sensing in tanks up to 500mm deep, particularly where traditional contact sensors might corrode or contaminate the liquid. The very small unusable area allows for accurate measurement close to the sensor. Its IP67 rating protects against splashes and condensation, and temperature compensation ensures accuracy despite temperature fluctuations in the tank environment.

Problem Solved

Monitors fluid levels without physical contact, preventing contamination and wear from corrosive liquids, and providing accurate readings in environments with varying temperatures.

3. Door/Gate Obstacle Detection for Industrial Access

With its robust nickel-plated brass housing, IP67 rating, and a sensing range of up to 500mm, this ultrasonic sensor can reliably detect obstacles in the path of automated industrial doors or gates. The two programmable outputs can be configured to stop the door/gate if an object is detected and provide a 'clear' signal for operation. The selectable sound lobe width can be adjusted to prevent false triggers from adjacent structures.

Problem Solved

Enhances safety by preventing automated doors or gates from closing on personnel or equipment, reducing damage and accidents, especially in demanding industrial settings with potential for water or dust.
