Product Overview

Use the LITUBO LT-300 when products from 5 g to 3 kg need reliable inline weight control on a 300 mm conveyor. We combine dynamic weighing, recipe-based limits, automatic rejection and optional line communication to remove underweight, overweight and incomplete packs before cartoning or shipment.

Typical Applications

• Prepared-food trays and meal packs
• Frozen food and meat products
• Large pouches and bags
• Bottles, jars and containers
• Pharmaceutical or cosmetic multipacks
• Cartons and packaged goods up to 3 kg

Detection Targets

• Underweight and overweight products
• Incorrect filling quantity
• Missing components or packs
• Incomplete cartons or multipacks
• Products outside recipe limits
• Weight grading or pass/fail inspection

​Working  Principle

Products are spaced and conveyed across the weighing section, where a load-cell system measures each item dynamically. The controller compares the measured value with the selected recipe limits. Products within tolerance continue to the next process, while non-conforming products trigger an alarm and the configured rejection device.
