Abstract
An apparatus for a rapid measurement of temperatures in a hot gas flow, in particular in a gas turbine. The apparatus includes a sensor having two two-dimensional, electrically conductive heating elements, which are attached to the surface of a common, electrically insulating sensor body.
Claims20
An apparatus for a rapid measurement of temperatures in a hot gas flow of a gas turbine, the apparatus comprising:
- an electrically insulating sensor body;
- a first two-dimensional electrically conductive heating element maintained at a first temperature;
- a second two-dimensional electrically conductive heating element maintained at a second temperature, the first temperature and the second temperature being different;
- and
- a resistor connected in series to the second heating element,
- wherein the first heating element and the second heating element are attached to a surface of the sensor body,
- wherein the first heating element is connected in parallel with the resistor and the second heating element;
- and
- an electrically conductive sensor head disposed at an end of the sensor body, the sensor head providing an electrically conductive connection between the two heating elements.
