ABSTRACT:
A temperature sensing device for monitoring high temperature exhaust gases of an internal combustion engine which includes a sensing element and a support for the sensing element including a mounting stem, and electrical connection means secured to the end of the mounting stem which is outside of the manifold. A gas seal connection between the sensing element and the supporting mounting stem is located at a point removed from the hostile operating environment within the manifold and the fit between the sensing element and the mounting stem is such that a slight freedom of movement is available at the portion of the mounting stem innermost of the manifold to thereby shift the point of highest stress to the gas seal and securing connection between the mounting stem and the sensing element.
