ABSTRACT:
A flame detecting thermocouple for use with a gas valve to insure that the pilot flame exists before the gas valve can turn on the main burner. The thermocouple has a first rod shaped element which is composed of a high potential side thermoelectric material such as Chromel, Inconel, iron-chromium alloy and a second rod shaped element composed of a low potential side thermoelectric material formed of a 0.7 to 2% yttrium, 45-70% copper and the remainder of the alloy is nickel, and the elements are welded together at their ends to provide a junction which can be heated by a flame to produce a thermoelectric output at the other ends of the element.
