A sensor assembly for a flame sensor apparatus includes a photodiode that generates a current. The sensor assembly includes a seal assembly supporting the photodiode. The seal assembly includes an inner conductor defining an inner conductor end. The inner conductor includes an inner conductor surface disposed at the inner conductor end. The photodiode is attached to the inner conductor end of the inner conductor and to a middle conductor end of a middle conductor. The photodiode is electrically connected to the inner conductor surface. The seal assembly is triaxial so as to protect the current generated by the photodiode. The seal assembly withstands temperatures up to or greater than about 325&#xb0; C. The seal assembly forms a hermetic barrier that, with the photodiode supported within a sealed volume, limits the passage of materials/gases through the seal assembly.

High temerature, hermetically sealed, triaxial mount for a light sensitive element

A flame sensor apparatus and a cable assembly apparatus are provided for use in sensing characteristics of a flame within a combustion chamber. The flame sensor apparatus includes an electrical assembly remote from a sensor assembly. A cable assembly extends between the sensor assembly and the electrical assembly. The cable assembly includes two cable ends and a housing that defines an internal volume. Cable fittings are connected to the cable ends through a first seal. An electrical cable is inserted through cable fitting openings in each cable fitting and the internal volume of the housing. A second seal is located in the annular spaces between the electrical cable and each cable fitting opening, configured to prevent moisture and contaminants from passing through the cable fitting opening. Additionally, a method of sealing an electrical cable and a flexible conduit is provided.
