Providing Feedback from Web Dancer to Manage Web Tension by Analog Inductive Sensors

As a web unwinds and feeds material into the process, the control system should compensate for minor changes in tension. The web tension control system registers these tension changes thru a dancer roll. previously, both a feedback potentiometer or an encoder-type product has been utilized by the purchaser to offer a signal to the machine controller, which adjusts drive speed/braking consequently that Both are subject to wear and tear on delicate bearing surfaces. To avoid this challenge, we need non-contact sensors.

Analog Inductive sensors are perfect for this application. Available in a variety of standard housings, their Condist® oscillator technology guarantees plenty longer working distances than standard ((as much as 40 mm). The sensors’ analog output offers resolution in the µm variety with high-quality temperature balance and repeat accuracy. The continuous, non-digitized output of those sensors is ideally fitted to recording the accurate movement of a constantly ‘dancing’ roll.
