Abstract
A composite active waveguide temperature sensor () incorporates a first, sensor portion () formed of an environment-resistant material such as ceramic coupled through an ultrasonically-transparent bond () to a second, waveguide portion () formed of an ultrasonically-transmissive material such as a metallic filament wire. By doing so, the sensor portion () may be positioned within a harsh environment and subjected to a temperature to be measured, and the waveguide portion () may be used to propagate ultrasonic energy to and/or from the sensor portion () to a location distal from the harsh environment for measurement of the temperature. The ultrasonically-transparent bond () between these portions () limits attenuation of and the introduction of reflections and other noise to an ultrasonic signal propagated across the bond ().
