The ZMGZ Series force measuring journals utilize the flexion beam principle. When the Journal is subjected to a force, bending stress is applied to the measuring web. Four foil-type strain gauges in a full Wheatstone bridge configuration measure the bending and thus the material tension. The position of the red point depends on the application. If the force acts in the direction of the red point, positive values will result from the measuring amplifier output.
The ZMGZ Series force measuring journals are used to measure the tension in continuous material processing lines. Force measuring journals are utilized with rollers that have an internal bearing. A bearing mounts to the bearing seat of the load cell and fits inside the roller. Thus the ZMGZ Series saves machine mounting space and providing a compact tension measuring roller assembly
