Abstract

The invention relates to a gas turbine, with a flow path for a hot gas, enclosed by a channel wall with at least one measuring probe, arranged in the channel wall, for determination of a parameter of the hot gas, said measuring probe comprising a temperature-resistant measuring tip in contact with the hot gas and a measuring line, arranged outside the flow path in a protective sleeve. According to the invention, such a gas turbine with a structurally uncomplicated protective sleeve for measuring lines from measuring probes, in which the measuring lines can be economically fitted and securely protected from excessively high operating temperatures, may be achieved, whereby the protective sleeve has a flow of coolant running therethrough which may be taken from a coolant supply connected to the protective sleeve.
