Loma CW3 Checkweigher

• Used for verifying product weight to ensure compliance with legal metrology regulations.
• Integral for quality control, detecting under-filled or over-filled packages on production lines.
• Often deployed in food processing for packaged goods such as frozen foods, baked goods, or confectionery.
• Suitable for pharmaceutical and cosmetic industries to ensure accurate product dosing and packaging.
• Utilised in logistics and distribution for package completeness checks and shipping weight verification.

Typical capacity

For this class of equipment, throughput commonly ranges from 60 to 200 packs per minute, depending on product weight and size.

Power supply

Units of this type typically require a standard industrial electrical supply, commonly 230V single-phase or 400V three-phase, 50Hz.

Weighing range

Loma CW3 checkweighers are generally designed to handle a broad range of product weights, from a few grams up to approximately 10-15kg, depending on the specific load cell configuration.

Accuracy

Typically offers high weighing accuracy, often within +/- 0.5g to +/- 5g, crucial for legal-for-trade applications.

Reject mechanism

This unit features a ram reject, which is common for efficiently removing out-of-spec products from the line.

Construction material

Commonly constructed from stainless steel, making it suitable for washdown environments and hygienic applications in food processing.

• What is a checkweigher used for?

  A checkweigher automatically weighs items in motion during production to ensure they meet specified weight tolerances, preventing under- or over-filling.

• Can this checkweigher handle different product sizes?

• What maintenance is typically required for a used checkweigher?
