Sensor device monitoring coupling force between workpieces via sensor element acted on by coupling force provided by coupling device

摘要

The sensor device has a sensor element (10,20) positioned so that it is acted on by the coupling force (6) between the workpieces (3,4) provided by a coupling device, for providing a corresponding electrical signal upon interrogation by an interrogation device, coupled to the sensor element by a signal cable connection or a radio signal link.
