Torsional vibration damper for damping of torsional vibration of e.g. crankshaft, of piston engine, has reading device for supplying transponder with electrical energy via electromagnetic waves and receiving temperature values from sensor

摘要

The damper (1) has a centrifugal mass (4) connected with a rotatable housing (2) in a receiving chamber (3) in an elastic manner. A temperature sensor (10) is attached in the housing, where the sensor exhibits a transponder, a coupling coil and a reading device (13) that is fixed opposite to the rotatable housing. The reading device supplies the transponder with electrical energy via electromagnetic waves, and receives temperature values from the sensor containing a radio frequency identification (RFID) chip.
