Abstract:
1. An apparatus, comprising: a first elongate section having a first flexible conductor enveloped by a first polytetrafluoroethylene jacket; a second elongate section having a second flexible conductor enveloped by a second polytetrafluoroethylene jacket; and an sensor section having an elongate flexible tubular shape, and including polytetrafluoroethylene material, the sensor section housing a resistance temperature detector element which is at least partially coiled and which is resistance welded to the first flexible conductor at a first weld and to the second flexible conductor at a second weld; wherein the sensor section at least partially envelops and overlaps the first elongate section and the second elongate section, with a first band crimping the sensor section to the first elongate section, and a second band crimping the sensor section to the second elongate section, and with the first and second welds disposed between the first and second bands, wherein the sensor section has no core for support and the apparatus is adapted to enable sensor flex in use.
