Applications of high temperature monitoring

The need for high temperature monitoring in industrial processes reveals more and more crucial to operate systems at the actual limits to take advantage of optimal working conditions. Moreover, the concept of health monitoring for devices operating under harsh conditions or environment rises during the last decades and requires the capability for accurate control with minimum invasive and perturbing approaches. The applicability of wireless SAW measurements has demonstrated in numerous situations (see particularly [1] and cited references within), but very few attempts were successfully achieved to remotely control SAW sensors in high temperature/harsh ambiances. In the same dynamics, the possibility to measure the actual temperature during nano-particles growth such as CNTs within the growth chamber was not demonstrated yet. However, it is a key issue to follow-up the growth process evolution and to provide a reliable diagnostic on optimal growing conditions of the nano-particles and nano-sized materials. Here again, the field is quite open for innovation and advances along the proposed approach.
