IEEE 1451 compliant magnetic rotary transducer with energy feedback channel

Industrial process control implies sometime the necessity to remotely operate devices placed in harsh or toxic environments, getting information from sensors powered up by batteries placed in the same environment. Thus appears the issue to periodically charge these power elements by physical removal. Hereby is developed and tested a magnetic rotary transducer which can provide energy feedback represented by periodic rectangular pulses of high voltage used to charge batteries and prolong the discharging cycle. The proposed architecture represents an IEEE 1451 compliant smart transducer communicating via industrial Ethernet.
