Abstract
A force sensor system for measuring forces that are transferred from film strips or sheet metal strips to a measuring roll during rolling in roll stands can be inserted into a cylindrical hole of a measuring roll under preload. The force sensor system includes a first force sensor and a preloading device for creating a preload on the first force sensor, so that the first force sensor can determine a force acting radially on the measuring roll. The first force sensor has a high sensitivity, which corresponds to the required measurement sensitivity of the contact force of the film strip or sheet metal strip. The force sensor system includes a second force sensor, which also can be placed under preload by means of the preloading device. The second force sensor is a statically measuring force sensor.
