Investigation of High-Temperature Sensors for Tube Monitoring Applications

Abstract: This report covers the investigation of the next generation of sensors to be used in the sensor based tube system known as SentusysTM. One essential feature of the next generation of sensors is high-temperature endurance. The sensors (strain gauges and thermocouples) have been produced by means of thermal spraying techniques, short-pulse laser ablation and laser cladding. It has been found that the sensors seem to work in general, however, much research and development remain.
