Abstract: The invention relates to a high-temperature sensor, which can be used at temperatures of at least 600° C. and comprises a metallic protective tube and a measuring resistance that is surrounded by a ceramic powder. The measuring resistance is connected to the electric cable by means of stress-relieved measuring resistance connecting wires and internal conductors. The latter are provided with a solid and/or flexible insulation consisting of a ceramic material. The measuring resistance and the internal conductors are arranged in a metallic protective tube, which narrows in the vicinity of the measuring resistance. The ceramic powder contains admixtures of oxygen-giving oxide compounds.

Abstract: A protective device for a submersible lance to be used in a vessel of molten material, such as steel, prevents undesirable deposition of the material at the juncture of lance and probe by having in the lance a channel for gas, and by having between the lance and the probe a gas-conducting disk which projects this gas circumferentially onto the lower surface of the lance.

Abstract: Apparatus for manipulating a probe which is to be coupled to a vertically movable probe lance, the lance having a longitudinal axis which is vertically oriented, which apparatus includes a supporting frame supported for pivotable movement about a stationary frame axis between a plurality of operating positions, an openable centering funnel supported by the frame, a lifting carriage supported by the frame for vertical movement relative to the frame, a probe holding clamp supported by the carriage at a location below the funnel, a probe separation device supported by the frame at a location below the probe holding clamp and pivotable relative to the frame about a separation device axis parallel to the frame axis, and a sample holding clamp supported by the frame at a location below the separation device, and in which the funnel is mounted to be vertically movable relative to the frame, and the apparatus further includes a support device connected between the sample holding clamp and the frame and supporting the
