Checkweigher FAQ

checkweigher faqWhat is the difference between an in-motion checkweigher and static checkweigher?

A static checkweigher can only weigh an item that is not moving (i.e. static). Static checkweighers cannot have any motion on the load cell since it can take several seconds to stabilize. In addition, any product movement causes the load cell readings to oscillate resulting in unstable readings.

An in-motion checkweigher (checkweigher) can weigh an item while in motion (i.e. dynamic) and then reject a product that is out of spec. Checkweighers must obtain accurate weighments in fractions of a second. Parameters such as product contents, product transfer and overall system design are much more relevant with checkweighers since moving parts can affect weighments. However, technology has improved significantly over the last decade such that in motion weighing is almost as accurate is static weighing.

Why are so many companies now using checkweighers?

Checkweighers are ideal for ensuring product consistency. They do this based on product weight. They offer 100% product sampling. Checkweighers can alert management to under-filled containers thereby preventing a potential recall. They can also alert supervisors to overfilling which costs the company lost revenues. Checkweighers do these tasks consistently, reliably and can have a payback of less than 12 months.

What is the payback for a checkweigher?

While every situation is unique, checkweighers typically have a payback of less than 12 months. Companies, like food processors, can fill millions of containers a year. Being able to identify an overfill condition by even a few grams per container and adjust the filler, can save a company tens of thousands of dollars a year.

With the rise of social media it is vitally important that customer receive exactly what they are expecting. Sending a few products out with 1 or 2 missing components can result in negative social media frenzy. That will ultimately hurt sales. Your company name is at stake and a checkweigher can help you maintain brand integrity.

What industries use checkweighers?

Checkweighers are ubiquitous throughout almost all industries. They are very prevalent in the food industry since almost all food is sold based on weight. However, they are also used in other industries such as the cell phone industry. Checkweighers are sensitive enough to detect a missing SIM card and divert the package for rework!

Even products that are sold by quantity (i.e. CDs, pills, screws) can have their quantity verified with a checkweigher. The close relationship between quantity and weight makes this possible.

If the quality of your process can be measured by weight, which covers about 99% of all processes, a checkweigher might be the solution for you.
