Enhanced Weighing Accuracy with an EMFR Force Balance Sensor
Leveraging the expertise we have cultivated as a balance manufacturer, we have incorporated an EMFR (Electromagnetic Force Restoration) force balance sensor. This achieves a readability of 0.002 g and a sorting accuracy of 0.012 g.
Flexible display positioning
The position of the operation display can be selected from either the front or rear of the conveyor to suit your factory workflow and layout.

Storable product info: Up to 1,000 products (including product images)
Product images can be quickly uploaded to the Checkweigher from a USB flash drive. The images can be easily registered as a thumbnail image for each product.
Up to 1,000 products can be registered and categorized into 10 different groups (up to 100 products group).

Automatic switching of product settings by reading barcode
By reading the barcode on a product, the product settings on the Checkweigher are automatically switched to those of the scanned product.*1

*1 Barcode reader shall be prepared by the customer.
User management
To operate the device, user name and user level are registered.
For each user registered, you can limit the operations they can perform depending on their user level.
Inadvertent operation can be avoided by assigning each user a user level from the four levels below.

Data summary
Various summary data such as histograms (frequency including defects), X-Bar Control Chart, R Control Chart, total summaries, etc., are available.
You can visually confirm fluctuation of weighing results and adjust your manufacturing machine accordingly.
After weighing, press the “PDF” key on the summary display. A PDF report is output to a USB flash drive.
