Abstract

A conductor leadthrough for a field device is for connecting two electrical conductors. The conductor leadthrough comprises an external conductor and a sealing apparatus. The sealing apparatus is divided into a first separation device and a second separation device. The external conductor comprises a hollow internal region that extends along a longitudinal axis of the external conductor. The first separation device and the second separation device are arranged along the longitudinal axis of the external conductor so as to be spaced apart so that they can separate a section of the hollow internal region of the external conductor. A pourable-sealing device is filled into the separated section of the hollow internal region of the external conductor so that the sealing apparatus can provide a leakage rate whose value is below a predeterminable value of a leakage rate. A signal of a predeterminable frequency can be transmitted along the longitudinal axis.
