Weighmaster Scales -

Applications & Use Cases

• Used in food production lines for verifying product weight against predefined targets.
• Essential for ensuring compliance with packaging regulations and reducing product giveaway.
• Integrated into end-of-line processes to identify under- or overweight packages before dispatch.
• Can be used for statistical process control to monitor filling accuracy over time.

Typical Specifications

Typical capacity

This specific unit is listed with a 5kg minimum and 50kg maximum. For this class of industrial checkweighers, capacities commonly range from a few grams up to 60kg or more, depending on the model and intended application.

Power supply

Checkweighers typically require a standard industrial electrical supply, commonly 230V, 50Hz, single-phase, though some higher-throughput or integrated systems may use three-phase.

Throughput

Throughput for checkweighers varies significantly, typically ranging from 50 to 300 packs per minute, influenced by product size, weight, and conveyor speed.

Accuracy

Accuracy for industrial checkweighers is typically high, often within +/- 0.1% to 0.5% of the target weight, crucial for regulatory compliance and waste reduction.

Construction materials

Units designed for food processing are commonly constructed from stainless steel (e.g., 304 or 316 grade) to meet hygiene standards and resist corrosion.

Footprint

The footprint of a checkweigher can vary, but for this class, it typically requires a linear space of 1 to 2.5 metres in length and 0.5 to 1 metre in width, depending on conveyor length and control panel integration.

Connectivity

Modern checkweighers commonly feature connectivity options such as Ethernet, USB, or serial ports for data logging, remote monitoring, and integration with factory management systems.

Frequently Asked Questions

• What is the primary function of a checkweigher?

  A checkweigher automatically weighs every item passing over its conveyor and compares the weight to pre-set upper and lower limits, rejecting items that fall outside this range.

• Can this type of equipment handle different product sizes?

• What kind of maintenance does a checkweigher require?

• Is calibration important for a checkweigher?

• What are the common rejection mechanisms?
