A temperature measurement system capable of operating in harsh environments including a temperature sensor having an antenna, diode, and dielectric layer disposed on the object of interest is provided, wherein the antenna includes a buried portion that extends through and is electrically coupled to the object of interest, and an exposed portion disposed upon an outer surface of the dielectric layer and the diode is coupled between the object of interest and the exposed portion of the antenna. The antenna is configured to receive interrogating signals from a transmitter, and to transmit response signals corresponding to the resonant frequency of the temperature sensor and its harmonics, which are indicative of the measured temperature of the object of interest. A receiver detects the response signals and correlates the frequency to a known temperature response of the dielectric material. Methods of making and using the temperature measurement system are also provided.

Condition-based Maintenance (CBM) systems significantly improve the effectiveness of maintenance programs for complex systems by optimizing the timing and focus of the procedure. The approach minimizes the associated costs. The proposed sensor system enables CBM sensors to be easily added to existing plants and equipment. The proposed system includes a unique power supply that utilizes waste heat from the plant equipment. In addition, the system eliminates most system interconnects through its wireless networked architecture of individual sensor nodes. The proposed system provides pressure and temperature sensors that may be used in the hot sections of turbine engines and mounted on rotating components. Commercial Applications and Other Benefits: The system and its individual temperature and pressure sensors will be effectively utilized in the development phases of power plant equipment such as gas and steam turbines. In addition the proposed system is the core of a health and usage monitoring subsystem for CBM for new plant construction and existing plant updates.

WST's thin-film passive wireless temperature sensor technology will be optimized to measure the surface temperature of turbine blades in the hot section of the gas turbine engine. This technology consists of a conformal, thin-film circuit that can be deposited on a blade. The minimal size and weight of the sensor insure that the static and dynamic characteristics of the blade are not altered. The wireless temperature sensor will be designed for current manufacturing techniques allowing easy fabrication on the curved surface of a compressor blade without the use of clean rooms. The sensor physical configuration will be optimized to allow volume manufacturing and then"after-market"installation on non-rotating surfaces of gas turbine engines. BENEFIT: This temperature sensor provides an effective monitoring tool for gas turbine engine developmental testing as well as in operational environments as part of a Condition-based-Maintenance system. Since the sensor is wireless, it will achieve a dramatic improvement in reliability when compared to previous wired solutions. When the sensor system development is complete, up to 100 temperature sensors may be installed in each engine providing a significantly improved picture of the environment within the engine.

Condition-based Maintenance (CBM) systems significantly improve the effectiveness of maintenance programs for complex systems by optimizing the timing and focus of the maintenance. Wireless condition monitoring systems can be installed without the need for cabling infrastructure. This provides considerable life cycle cost savings. This project develops a waste heat harvesting power supply that powers wireless condition monitoring systems enabling real time sensor data collection. The target application is power generation plants with their considerable sources of heat. The Department of Energy and the gas turbine engine community place a high priority on the development of sensors for harsh environment. A pressure sensor, capable of operation at 800 degrees Celsius, and measuring pressures up to 1000 pounds per square inch is also being developed under this program. The wireless sensor power supply utilizes Thermo-electric Generator devices to supply an adjustable output voltage of 3.3 to 12 volts direct current. The power supply can be used with existing wireless systems in the market, potentially enabling them for real time data collection. An advanced generation wireless condition monitoring network node using the 802.15.4 protocol is being developed. It contains temperature, vibration, pressure, and general sensor inputs and is designed for real time sensor operation. The pressure sensor is a standalone component that can also be used in the wireless condition monitoring system. Commercial Applications and Other Benefits: The harsh environment pressure sensor is a high priority development for gas turbine engines. It can be used for developmental testing or operational environment condition monitoring. The TEG PS will benefit existing off-the-shelf wireless condition monitoring systems by providing power for their network node/sensor interfaces and potentially enabling real time sensor data collection. The wireless condition monitoring system can be used for critical real time monitoring applications in power generating plants and other industrial applications.

Wireless Sensor Technologies has for several years been developing a passive Wireless Temperature Sensor (WTS) for gas turbine engine and other harsh environment applications under the under sponsorship of the Air Force (Non-destructive Test Program) and the Navy (SBIR Topic N08-004). Once productized, the functional and operational goals for the sensor as they relate to the gas turbine engine are to:? Measure the surface temperature of the Yttria Stabilized Zirconia Thermal Barrier Coatings (YSZ TBC's) typically applied to turbine blades in the hot section of the gas turbine engines? Measure temperature at specific locations on the surface of the combustor liner to determine both radial and circumferential temperature variations (pattern factor)o Thin film passive wireless sensors will be arrayed in an annular ring around the combustor to determine pattern factor in an effort to sense the uniformity of combustion downstream from the fuel injectors.? Measure the surface temperature of any area of interest using a weldable coupon version of the wireless temperature sensor? Measure heat flux across the section thickness of thermal barrier coatings by pairing several of the proposed wireless temperature sensors (for the surface temperature measurement of TBC's.This program will characterize the longterm drift and reliability of the WTS and in Phase 2 result in a sensor with a TRL level of 6 to 7.

Wireless Sensor Technologies will develop a passive wireless temperature sensor system for gas turbine engine applications under the referenced SBIR. Once productized, the functional and operational goals for the sensor are to 1) Measure the surface temperature of the Yttria Stabilized Zirconia Thermal Barrier Coatings (YSZ TBC’s) typically applied to turbine blades in the hot section of the gas turbine engines, 2) Measure temperature at specific locations on the surface of the combustor liner to determine both radial and circumferential temperature variations (pattern factor). Thin film passive wireless sensors will be arrayed in an annular ring around the combustor to determine pattern factor in an effort to sense the uniformity of combustion downstream from the fuel injectors, and 3) Measure heat flux across the section thickness of thermal barrier coatings by pairing the proposed wireless temperature sensor (for the surface temperature measurement of TBC’s) with a similar wireless temperature sensor being developed under another program. The combination of that sensor and the sensor being developed under this SBIR program will allow the measurement of heat flux across the TBC and open the possibility of TBC health monitoring.
