Gas turbine with protective case for measuring probe and method for protecting measuring wiring laid in protective case

摘要

The turbine has a measuring sensor (26) arranged in a channel wall (22) in an area of a protective sheath (38) to determine a parameter of a hot gas. The sensor has a measuring tip (30) standing in connection with the hot gas in a temperature resistance manner and a measuring cable (34) installed in the sheath. The sheath is pass throughable by a cooling medium, which can be withdrawn of a coolant source connected with the sheath.
