  • Patent number: 4131756
    Abstract: A thermocouple-probe assembly for use in the measurement of temperature in a gas-turbine engine. The assembly has a central hub which is for mounting on the central exhaust-cone of the engine and twelve elongate thermocouple probes which extend radially from the hub such that their operative tips are located in the gas flow through the engine. Each probe has two Chromel-Alumel junctions at its operative tip, the junctions of each probe being electrically interconnected by means of four concentric electrically-conductive rings which are mounted coaxially within the hub. Two of the rings are of Chromel and two of Alumel, the wires forming the thermocouple junctions being connected to rings of the same material by means of small edge portions of the rings which are turned back and crimped around each wire. External electrical connection to the probes is made by cables connected to the rings within the hub.
