Patent attributes
A device for monitoring the service life of a machine-technical installation includes a sensor module and at least a measuring sensor for detecting stresses and expansions from a structural component of the machine-technical installation, a microcontroller, an antenna arrangement and a current source; the sensor module being in bi-directional connection with a data processing unit and having an antenna arrangement integrated therein, the antenna arrangement including a low-frequency antenna by means of which the sensor module is turned on and off and a high-frequency antenna for sending and receiving high frequency signals and wherein the sensor module can transition from an operating mode into a stand-by mode for energy efficiency and is reactivated through a signal from a detector element.
