IMGZ035 – Measuring roller with two integrated force sensors

The force measuring rollers of the IMGZ035-series combines force sensor and roller. The IMGZ035-series design, incorporating dual bending beams, eliminates the load-specific influences of torque and ensures accurate measurement at any position on the roller while maintaining the parallel position of the material and eliminating angular deflection. The movement of the bending beams is detected by a set of strain gages arranged in a full bridge bridge. The resulting electrical signal, which is proportional to the applied force, is then amplified for use in monitoring or controlling web tension. With the superior performance of the IMGZ-Series, accurate tension readings are obtained even with low web wrap angles and low material tension.
