Standard weighing terminal ST-Ex

Approved for Ex zones 1/21 and 2/22

As an interface between load receptors, PC, and peripherals, the standard terminal ST-Ex can be used to accomplish various tasks: from entering data to complex data analysis, from simple weighing to sophisticated real-time system controls and data processing.

Area of Use

Especially suitable for use in potentially explosive zones, e.g.:

  • in goods receiving as station for operating data recording
  • in production and manufacture: as a control instrument for counting, dosing and filling processes
  • In shipping: as a commissioning unit for isometric parts, as a creation tool for material balances

Highlights

  • unites weighing and monitoring technology in a single compact unit
  • manages two weighing modules
  • can be seamlessly integrated into existing production structures and networks

Terminal with the finest equipment

The Bizerba ST-Ex shines with a shapely, hygienic stainless steel design and has a clearly arranged membrane keyboard with mechanical pressure points and freely configurable function keys.

 

Combinable and placeable in various ways

All standard ST-Ex weighing terminals are designed to be connected to up to two load receptors. Serial and parallel interfaces can be used to connect to precision weighing terminals, PLC controls, PCs, printers, or scanners. The terminal is networked over Ethernet or Profibus DP and facilitates integration into a company network. The stainless steel housing is suitable for installation on a table, it can be wall-mounted or free-standing on a universal stand.

 

High performance in many different sectors

The high IP 68 safety class and the low-maintenance design are guaranteed for a wide range of industrial applications. Whether used in sensitive environments or under harsh industrial conditions the ST-Ex terminal is protected against moisture, cold, dust, and corrosion.
