Abstract
The present invention relates to an exhaust sensor () comprising a tubular support body () receiving a measurement probe (), a first end of said probe extending beyond a first end of the tubular support body through an opening therein, and a second end of said probe being secured to an electrical connection connector () housed inside the tubular support body () and fitting closely against its walls. According to the invention, the measurement probe is sealed inside the tubular support body () and is thermally decoupled from the environment outside the tubular support body by means of an assembly of spacers () made of ceramic and of glass, the spacers being threaded around the measurement probe and distributed inside the tubular support body between the electrical connection connector and the first end of the tubular support body so as to provide at least two separate cavities, said spacers providing leaktight sealing between the measurement probe and the tubular support body.
