  • Page 7: Overview

    1. OVERVIEW The VR TENSION system is a combination of a tension sensor and a tension amplifier and can be used for measuring the web load (tension). The tension amplifier displays the load value measured by the tension sensor. At the same time, an analog voltage or current corresponding to the load will be output to external devices (recorder, PLC, or tension controller etc.).
