<p>The measuring device has a device (2) for conversion of electromagnetic waves e.g. radio waves, into electric current, and a measuring and transmitting device (3) electrically connected with the device for conversion. The measuring and transmitting device measures a physical parameter by a temperature sensor (4) that is arranged in a measuring region to be monitored. The transmitting device sends a measured value, and a receiver (5) receives and analyzes the measured value of the transmitting device.</p> |
