A detector for use in a detecting device and intended to establish the occurrence of a change in the conductivity of a medium comprises one or more electrical conductors. The respective electrically insulated conductors (4a', 4b') are worked mechanically and/or prepared at pre- determined, restricted locations (10, 11) thereon in order to expose parts of the conductor material (12, 13). The electrical conductors (4a'. 4b') comprise two or more twined or twisted conductors which are electrically insulated from one another. The electrically insulated layer (8, 9) is removed from the outermost parts of the conductors with the aid of a mechanical working process or the like. |
