Abstract
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.
