Weighmaster Scales -

Applications & Use Cases

• Used for verifying product weight compliance in packaging lines.
• Essential for quality control in food processing to minimise giveaway and ensure regulatory adherence.
• Integrated into production lines for statistical process control and data logging.
• Suitable for end-of-line inspection of packaged goods before dispatch.

Typical Specifications

Typical capacity

For this class of equipment, units commonly handle items from a few grams up to 50kg, with the listed unit specifically noting 5kg to 50kg.

Power supply

Checkweighers typically operate on standard industrial single-phase (230V) or three-phase (400V) electrical supplies, 50Hz.

Throughput

Throughput rates vary significantly by model, typically ranging from 30 to over 300 items per minute, depending on product size and accuracy requirements.

Accuracy

Accuracy for this type of equipment is commonly within +/- 0.5g to +/- 50g, depending on the weighing range and application.

Construction materials

Units in food processing environments are typically constructed from stainless steel (e.g., 304 or 316 grade) for hygiene and corrosion resistance.

Footprint

The footprint for checkweighers can vary, but typically ranges from 1m to 2.5m in length and 0.5m to 1m in width, excluding any infeed/outfeed conveyors.

Connectivity

Modern units commonly feature Ethernet, USB, or serial (RS-232/485) ports for data logging and integration with factory management systems.
