ABSTRACT:
An igniter and flame sensor electrode assembly which is suitable for mounting in a conventional thermocouple bracket in close proximity to a fuel burner so that the assembly can be employed in an ignition system to ignite the burner and sense a flame due to its conductive and/or rectification properties. The assembly is shaped similar to a conventional thermocouple and includes a tubular shaped probe having an ignition port in which the igniter element is mounted and a sleeve therearound which forms the flame sensing electrode. The housing for the igniter and flame sensor electrode is formed in two halves and the electrical connections to the flame sensing electrode and igniter element are made by lead wires located in axial bores within the housing.
