Ultrasonic probes for high temperature measurements in immersion are presented. These probes consist of piezoelectric transducers and buffer rods, are operated in the pulse-echo mode. The operating temperature is up to 215 °C and there is no need for a cooling system. For imaging purposes, one end of the clad buffer rod is attached with a piezoelectric transducer and the other end is machined into a semi-spherical concave shape that provides the focus. The operating frequency is 5 MHz. Ultrasonic images produced using mechanical raster scan and the measurements, when the probes are fully immersed in silicone oil at elevated temperatures, are presented. The importance of the signal-to-noise ratio in the pulse-echo measurement is discussed.
