TECHNICAL NOTE | High temperature acoustic emission transducer – pencil break test

This technical note explores the suitability of Ionix’s HotSense platform for acoustic emission ( AE ) transducers for such applications, without the need for waveguides or IEPE electronics due to its high sensitivity across a wide temperature range, by the application of a standard pencil break test conducted at 350 °C. The outcomes demonstrate that the HotSense AE transducer exhibits outstanding sensitivity at this temperature, maintaining a performance level similar to that at room temperature.
