Abstract
A thin-film thermocouple () is disclosed for use with a gas turbine component. The thermocouple may be formed on a non-planar substrate () having formed thereon an electrically insulating layer () capable of maintaining its insulating properties at gas turbine operating temperatures. A first thermocouple leg () made of pure platinum is then deposited on the dielectric layer (). A second thermocouple leg () made of another pure metal or a transparent ceramic oxide is also formed on the dielectric layer () wherein the first and second thermocouple legs make ohmic contact at a first end of each leg to form a hot junction () for conversion of heat into an electrical signal. The thermocouple may be deposited on a surface of a thermal barrier coating or between a thermal barrier coating and an underlying metal substrate.
