Description

HBM WE2111 – is a digital weight indicator with new generation interfaces for commercial use. It meets the highest industrial requirements.

The device has Ethernet and USB interfaces for integration into various systems.

Parts of the internal software of the device, which are not responsible for operation in the mode of commercial use, can be officially updated via the USB interface. At the same time, consistent compliance with strict modern norms and directives (the latest requirements of WELMEC, Directive 2009/23 / EC) is ensured.

An additional advantage of the device is a data storage device for commercial use, which provides reliable confirmation of weight data in accordance with legal requirements and, accordingly, documented measurement quality.

Main characteristics:

  • Connection to 8 weighing strain gauges of 350 Ohm
  • Gross, net, tare, printing
  • Measurement / calibration range up to 3,000 d
  • According to the OIML test protocol up to 10,000 d
  • Ethernet, USB and RS-485 / RS-232 interfaces
  • Complies with EMC directives (EN 45 501)
  • RAM for commercial use mode data storage (DSD)

Modifications of HBM WE2111:

  • WE2111-AC – the possibility of application in all regions of the world due to the use of a power supply unit with a universal input from 110 to 230 V alternating current, an additional output of 12 V direct current.
  • WE2111-ZS – control of automatic weighing processes using a variable module with 8 digital inputs / outputs.
  • WE2111-ZCC – regulation or management of additional processes of a higher level.
  • WE2111-ZH – the possibility of industrial application thanks to the stainless steel case.
  • WE2111-ZT – low-cost and fast assembly in office conditions.
  • WE2111-R2 or R4 – protection against electromagnetic interference and in-phase component due to interfaces with galvanic isolation.
