WEIGHING SYSTEM WITH STX 4000

The system includes:

• 2x STX 4000 terminal
• GSW Automat software
• 1x Desktop RFID card reader
• 25 x RFID cards

WEIGHING OPERATION SCHEDULE

A vehicle enters the weighbridge.
If the driver has got the RFID card, he holds it in front of the terminal. If it is his first visit in the plant, the driver goes to the customer service centre in order to register the vehicle in the system.
The system identifies the business partner on the basis of the RFID card. Upon the correct identification of the card by the system, the display shows: the vehicle registration plate number, the name of the company to which the card is assigned and the weighed product. The driver is allowed to select the weighed product. The driver can scroll the products by means of up/down buttons or enter the product code.
As soon as the driver accepts the entered data, the weighing process begins.
Upon stabilisation, the weighing result is saved in the database. The driver sees a message confirming the completion of the weighing operation, displayed on the display.
Upon completion of the weighing operation, a printer installed in the terminal prints out a weighing ticket. When the vehicle leaves the weighbridge, the system is ready to perform another weighing operation.

In case of double weighing operations (enter/exit), the system detects by itself the performance of the first weighing operation and automatically calculates the net weight of the cargo.
