Abstract
The invention relates to a device for measuring temperature in a gas duct. The device (1′) comprises a body (3′) for supporting a temperature sensor (4′), the sensor comprising a head (7′) and at least two wires (8′) connecting the head (7′) to means for acquiring a temperature-measurement signal. The supporting body (3′) is arranged so as to be inserted into an orifice of a wall of the duct in order to immerse the head (7′) of the sensor (4′) in the gases of the duct. The supporting body (3′) comprises a bottom collar (12′), having a top end surface (17a′), in which are arranged at least two channels (9′) for guiding and holding the wires (8′), arranged to allow the mounting of the sensor (4′) in the supporting body (3′) and the holding of the wires (8′) in order to hold the head (7′) of the sensor (4′) at a distance from the top end surface (17a′) of the collar (12′).
