Abstract:

There are provided embodiments of a sensing device that comprise a sensing element, a substrate, and a bonding element, each being selected for environments that utilize caustic working fluids such as automotive fuel. Material for use as the bonding element can form molecular bonds with ceramics and glass. In one embodiment, the sensing device comprises a receptacle or cavity, in which are located the sensing element and the bonding element. This configuration facilitates the formation of bonds between the bonding element and each of the sensing element and a peripheral wall of the cavity. Such bonds are configured in a tensile bonding area and a shear bonding area, the combination of which is useful to secure the sensing element in the cavity. The sensing device can further comprise a seal such as an o-ring disposed in annular relation to the substrate to seal the sensing device to a peripheral device such as a fluid fitting, which may be found in a fuel system of an automobile.
