The MAGPOWR CSR series is a cantilevered tension
sensing roller 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 machine idler roller, the CSR tension sensing roller delivers precise web tension measurement with low temperature drift due to a full Wheatstone bridge construction on each load cell inside the roller.
