AJA - Checkweigher System

Applications & Use Cases

• Ensuring products meet specified weight tolerances in food packaging lines.
• Minimising product giveaway and reducing material waste.
• Identifying under-filled or over-filled packages for quality control.
• Complying with legal metrology requirements for pre-packaged goods.
• Sorting products into different weight categories.

Typical Specifications

Typical capacity

Throughput commonly ranges from 60 to 300 items per minute, depending on product size and weight.

Power supply

Typically requires a single-phase 230V AC supply, with some larger units needing three-phase.

Weighing accuracy

For this class of equipment, accuracy is commonly within +/- 0.5g to +/- 2g, depending on the load cell and product.

Product weight range

Units typically handle products from a few grams up to 10-20 kg, though specific models vary.

Conveyor belt width

Commonly found with belt widths between 150mm and 400mm, suitable for various package sizes.

Footprint

A typical checkweigher system requires a floor space of approximately 1.0m to 2.5m in length and 0.5m to 1.0m in width.

Construction materials

Often constructed from stainless steel for hygiene and durability in food processing environments.
