The MAGPOWR ISR series is a dead shaft tension sensing roller supported on both sides that uses tension sensors embedded in the roller to provide a signal proportional to tension in any unwind, rewind
or intermediate web processing application.

When installed in place of a standard dead shaft idler roller, the ISR integrated tension sensing roller delivers precise web tension measurement with low temperature drift due to full Wheatstone bridge
construction on each load cell inside the roller.
