THERMOCOUPLE FOR GAS TURBINE ENVIRONMENTS |
摘要 |
A thin-film thermocouple (12) is disclosed for use with a gas turbine component. The thermocouple may be formed on a non-planar substrate (22) having formed thereon an electrically insulating layer (34) capable of maintaining its insulating properties at gas turbine operating temperatures. A first thermocouple leg (26) made of pure platinum is then deposited on the dielectric layer (34). A second thermocouple leg (28) made of another pure metal or a transparent ceramic oxide is also formed on the dielectric layer (34) wherein the first and second thermocouple legs make ohmic contact at a first end of each leg to form a hot junction (30) 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.
