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?

Yes, checkweighers are typically designed with adjustable conveyor speeds and sometimes adjustable guide rails to accommodate a range of product sizes within their specified weight capacity.

What kind of maintenance does a checkweigher require?

Routine maintenance typically involves cleaning, calibration checks, and inspection of belts, sensors, and mechanical components to ensure continued accuracy and reliable operation.

Is calibration important for a checkweigher?

Yes, regular calibration with certified weights is critical to ensure the checkweigher maintains its accuracy and provides reliable measurements for quality control and legal compliance.

What are the common rejection mechanisms?

Common rejection mechanisms include air blast, pushers, or drop-down conveyors, selected based on product fragility, speed, and line integration requirements.

Typical context for this category of equipment. Always confirm specifics with the seller.

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.
