RMGZ9 – Freely configurable cantilever force measuring roller
- Nominal forces from 50 to 1000 N (11 to 220 lbf.)
- Overload protection up to 10-times nominal force, measuring body from stainless steel
- Measuring range 30:1, accuracy class ±0.5 %
The force measuring rollers of the RMGZ9-Series combine force sensor and roller. The RMGZ9-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 circuit. 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 RMGZ9-Series, accurate tension readings are obtained even with low web wrap angles and low material tension.
