About Checkweighers
 

Checkweighers are weighing systems used to verify that the weight of a packed product is within prescribed limits. It weighs pack of product that moves along a production line, classify them by weight and then sort or eject by weight class.

Performance specifications for checkweighers include linearity, mean error, repeatability and accuracy. 

Checkweighing linearity measures the closeness in weight between an actual package and a test package. The difference or error between these two measurements indicates the degree of linearity.

Mean error is the absolute value of the difference between the actual weight and the average weight of the pack as reported.

Checkweighing repeatability is measured with standard deviation in order to describe the variance in weight from weighing the same mass multiple times. As a rule, checkweighers with greater repeatability or precision have lower standard deviations.

Discover What You’ve Been Missing … Checkweighers can be integrated with food, industrial and pharmaceutical production lines for various quality control purposes.  Often, the installation of an accurate checkweigher provides profit benefits to the user by controlling filler or scale accuracy to minimize product give away.  Systems are also used to assure compliance with label weight regulations and to eliminate consumer complaints associated with missing item or low-weight packaging conditions.  Line efficiencies can be tracked and 'give away' can be calculated providing an opportunity to stream line production and save costs within the process.

In short, the checkweigher is an important part of a quality control program and a means to provide benefits to the company.
