The EMGZ321, 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. 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.
