TEMPERATURE PROBE

A temperature probe for determining a temperature in a gas flow is disclosed. The probe comprises a probe body (11). A temperature sensor (50) is provided as a free flow temperature sensor to measure a free flow temperature of the gas flow and a temperature sensor (60) is provided as a total temperature sensor to measure a total temperature of the gas flow. A method of determining a temperature in a gas flow comprises measuring a flow temperature in a free gas flow, providing a static gas volume in which essentially all kinetic energy of the flowing gas is recovered and converted into thermal energy, and measuring a total temperature in the static gas volume. A combination of both measurement signals enables on the one hand an accurate determination of the total temperature of a gas flow, which is representative of a specific total enthalpy, while at the same time enabling the detection of fast and transient temperature changes.
