A parasitically powered remote sensing device for monitoring an industrial system. The device comprising a tuned transducer which converts stray energy emitted by the system into an electric potential for consumption by a remote sensing device and/or a wireless communications link. In an alternate embodiment the remote sensing device further comprises an energy storage element connected to the transducer to provide the sensing element and wireless communications link with the electric potential when the stray energy is insufficient to power the remote sensing device.
