<p>The device has a node point attached to an enclosed sub-system (1), where a wireless connection i.e. radio connection, is provided for connecting the node point to a control system and/or another node point. A separate energy generation system i.e. thermoelectric generator, is provided for energy supply of the node points with an attached sensors and/or actuators. The energy generation system utilizes a temperature difference between a region heated by process energy e.g. water vapor, and a region cooled by the process energy for energy generation. An independent claim is also included for a method for receiving measuring data in a paper and/or tissue and/or cardboard and/or packaging paper producing machine.</p> |
