EMGZ321 – Digital, dual channel measuring amplifier with web browser interface

  • Precise tension monitoring over the measuring roller
  • Easy to operate and provides flexible set-up
  • Provides special monitoring functions and flexibility for application changes
  • DIN Rail, Wall Mount (IP 65), and panel mount

The EMGZ 321, a left /right strain gauge amplifier, measures the material tension on both sides of the roller independently. Thus it is possible to monitor the load distribution over the measuring roller with great accuracy.

The EMGZ 321 series can be used in connection with all FMS force sensors. This high-grade product comes as a plug & play unit and is easy to setup. More advanced users can access all the internal parameters via a clearly arranged front panel, through an

Ethernet /IP interface, or in a peer to peer configuration from a laptop or local PC.
