What are in-motion checkweighers?
In-motion checkweighers are a type of scale that is integrated into a conveyor belt. As products move along the conveyor belt, they are weighed, and their weights are compared to preset specifications. If a product is over or underweight, it is automatically diverted from the main production line for further inspection or correction.

In-Motion Checkweighers: An Essential Tool for Quality Assurance
In today’s competitive manufacturing environment, it is more important than ever to ensure that products are of the highest quality. In-motion checkweighers are an essential tool for quality assurance, as they can help to ensure that products are the correct weight and meet all necessary specifications.
What is an in-motion checkweigher?
An in-motion checkweigher is a type of scale that is integrated into a conveyor belt. As products move along the conveyor belt, they are weighed, and their weights are compared to preset specifications. If a product is over or underweight, it also is automatically diverted from the main production line for further inspection or correction.
Advantages of in-motion checkweighers
In-motion checkweighers offer several advantages over traditional static checkweighers, including:
- Increased throughput: can weigh products at speeds of up to 1,000 products per minute, which can significantly increase throughput and productivity.
- Reduced labor costs: highly automated, which can also help to reduce labor costs.
- Improved accuracy: typically more accurate than static checkweighers, as they can weigh products while they are in motion.
- Reduced product waste: Also helps to reduce product waste by identifying and diverting over and underweighting products before they reach the customer.
Types of in-motion checkweighers
There are a variety of different types of checkweighers available, each with its unique features and benefits. Some of the most common types of checkweighers include:
- Belt weighers: Belt weighers are the most common type of in-motion checkweigher. They use a series of load cells to weigh the product as it passes over the conveyor belt.
- Roller top scales: Roller top scales use a series of rollers to support the product as it is weighed. This type of checkweigher is also ideal for products that are delicate or easily damaged.
- Integrator scales: Integrator scales use a series of load cells to weigh the product as it passes over the conveyor belt. They also use a computer to integrate the weight data over time to obtain a more accurate measurement.
Choosing the right in-motion checkweigher
When choosing a checkweigher, it is important to consider several factors, including:
- Product type: The type of product being weighed will determine the type of checkweigher that is needed. For example, delicate products may require a roller top scale, while heavy products may require a belt weight.
- Throughput requirements: It is important to choose a checkweigher that can handle the desired throughput.
- Accuracy requirements: The required accuracy of the checkweigher will depend on the product being weighed and the industry standards.
- Budget: These checkweighers can range in price from a few thousand dollars to tens of thousands of dollars. It is also important to choose a checkweigher that fits within the budget.
Conclusion
In-motion checkweighers are an essential tool for quality assurance in a variety of industries. By helping to ensure that products are of the correct weight and meet all necessary specifications, in-motion checkweighers can help to reduce product waste, improve productivity, and reduce labor costs.
