Arrangement for wireless electric power supply of number of sensors and/or actuators has thermoelement for converting thermal energy produced by heat generator into electrical energy

摘要

The arrangement has at least one heat generator connected to a machine with a number of sensors and/or actuators (1.1-1.s), which have a thermoelement for converting the thermal energy produced by the heat generator into electrical energy. The heat generator is switched on and off depending on a comparison of the difference in the measured air and machine temp. An Independent claim is also included for a sensor or actuator and for a system for a machine with a number of sensors and/or actuators.
