All Yamato I-Series checkweighers can be equipped with a metal detector.

Highest hygiene requirements fullfilled

The machines meet the highest quality and hygiene standards in the industry. With a protection class of IP67 and IP69, the I-Series checkweighers can be used for all kinds of wet applications. The machines can easily be integrated into any packaging process and fit your individual requirements. The checkweighers are available with a large range of length and width of belts and allow for a highly customized design.

User-friendly operation

The Yamato checkweighers of the I-Series are characterized by their intuitive operation and easy maintenance. Due to the user-friendly operation menu, even operating staff with little experience is be able to handle a checkweigher of the I-Series.

A maintenance history as well as a schedule for future maintenance interventions can be easily controlled via the menu guidance system. The intelligent software ensures a reliable and constant production flow.

Checkweighers in combination with metal detectors

The modular design of the metal detector ensures the flexibility of customizable packaging lines. The Yamato integrated combination – Metal Detector & Dynamic Checkweigher – is a sophisticated solution. It conforms to both HACCP and BRC design criteria and is compatible with IFS production monitoring.
