Engine signal double-channel receiving coil

The utility model relates to an engine signal double-channel receiving coil which adopts two sets of coils. An inner hanger is arranged at each of both ends of an iron core formed by the superposition of silicon electric sheet steel with high magnetic conductance, and an induction coil is respectively installed in each of the inner sides of inner hangers on both ends of the iron core; the iron core on which the induction coils and the inner hangers are installed in a plastic casing of which the middle is filled with silica gel, both ends of each coil group are connected to four cables which are four-core shielded cables, and two induction coils arranged on the same end head of each of the engine signal double-channel receiving coils above a left and a right rails are connected in series. The engine signal double-channel receiving coil has the advantages of strong seal performance, small volume and light weight.
