Sensor system for machine tool with sensor, comprises measuring device which measures physical variables appearing in machine tool, and energy supply unit for supplying measuring device of sensor

摘要

The system comprises a measuring device, which measures one of the physical variables appearing in a machine tool, which has a correlation with a machining operation that is carried out by the machine tool. An energy supply unit supplies the measuring device of a sensor (100). The energy supply unit picks up wirelessly electric energy from a surrounding electromagnetic field. Another energy supply unit supplies the measuring device of the sensor. The latter energy supply unit has a battery which is formed as a rechargeable accumulator.
