Application weighing terminal iS50-Ex

For hazardous areas classified as zones 1 and 21

The industrial weighing terminal iS50-Ex suitable for harsh industrial environments combines weighing and control technologies in only one compact unit. It is provided with a large 7" full graphic display and an alphanumerical keyboard.
The iS50-Ex with stainless steel housing is manufactured to meet industrial requirements complying with protection type IP 65 and can be used as a tabletop, wall-mounted or stand-alone device.

Area of Use

The Ex weighing terminal is designed for hazardous areas. It establishes weight data, controls components such as dosing systems and records all operating data. In addition to weighing functions, it provides programs for the following applications:

  • Counting
  • Dosing
  • Recording of statistical data in compliance with prepack regulations
  • Tolerance control


  • high protection type IP 65 for use in harsh environments, corrosion-, dust-, and water-proof
  • for connection of up to two load receptors
  • 7" full graphic display, resolution 800 x 480
  • Display color indication during weighing with tolerance control
  • robust and easy-to-clean stainless steel housing

Whether for dosing, counting or tolerance control the iS50-Ex offers a suitable software solution and all necessary interfaces.

All these important functionalities are safely integrated in a sealed and robust housing in order to ensure that the iS50-Ex withstands harsh conditions.
