Abstract:
1. A temperature sensor for a burner, said sensor comprising: two metal wires implementing a thermocouple; a protection sheath receiving the two metal wires; a head in metal material having a front side intended to be facing the environment, the temperature of which is intended to be measured, and a rear side opposite the front side; said two metal wires being connected in a thermal exchange relationship to said rear side of said head, in which said head comprises a front portion connectable to a burner wall of said burner so that the thermocouple is connectable to the burner by means of said metal head; wherein said head comprises a front portion intended to be inserted in a sensor seat of a burner wall of the burner; a first positioning surface suitable to engage an inner surface of the sensor seat so as to implement a positioning reference of the head in the plane of the burner wall; a second positioning surface transverse to the first positioning surface and suitable to abut against said burner wall in the proximity of said sensor seat, so as to implement a positioning reference of the head in the transverse direction to the burner wall plane and said front portion comprises a measurement surface intended to be exposed to the environment, the temperature of which is intended to be measured, and said first positioning surface is transverse to said measurement surface, and said head comprises a shoulder defining an abutment surface facing the front side and forming said second positioning surface, wherein said front portion projects from said shoulder towards the front side and comprises an annular side surface substantially perpendicular to the measurement front surface and forming said first positioning surface.
