Explosion-proof magnetic transducer (11) comprising a magnetic unit (13), a sensor unit (15) and an electronic control unit (17), wherein the magnetic unit (13) is associatable to a body moving circularly or rectilinearly or according to a combination of these movements, wherein the sensor unit (15) comprises a detector device (19) capable of causing the variation of at least one electrical quantity in an electric signal passing through said device, upon variation of a magnetic flux in a surrounding magnetic field, wherein the electronic control unit (17) comprises an amplifier (21) of the amplitude of said electric signal, wherein when the transducer (11) is working the electric power absorbed by said sensor unit (15) is lower than the one absorbed by said electric control unit (17) and wherein said sensor unit (15) and said control unit (17) are separate from each other and are connected by an electric cable (23). |
