The invention discloses a non-magnetic field armored signal cable in the technical field of signal cables. The non-magnetic field armored signal cable includes a non-magnetic metal core. A magnesium oxide cylinder sleeves the surface of the non-magnetic metal core wire. A filling layer is fixedly connected at the interlayer between the non-magnetic metal core wire and the magnesium oxide cylinder,the surface of the magnesium oxide cylinder is fixedly connected with a non-magnetic austenitic stainless steel pipe, the surface of the non-magnetic austenitic stainless steel pipe is fixedly connected with a fireproof layer, and the surface of the fireproof layer is fixedly connected with an antirust layer. Through cooperation of the non-magnetic metal core, the magnesium oxide cylinder and thenon-magnetic austenitic stainless steel pipe, the non-magnetic field armored signal cable is wide in temperature measuring range, is shock resistant and high temperature resistant, and produces temperature difference electric
