Morgan Advanced Materials has launched of a range of piezoelectric materials that deliver reliable sensing and monitoring in high-temperature environments above 200ºC.
Based on the proven properties of lead zirconate titanate, the new materials are suitable for both vibration and pressure sensing for applications in automotive and other industries.
The range is ideal for long-term non-destructive testing as it enables in-situ continuous fault detection at temperatures of up to 250ºC. Previous materials of this kind have had to offer a compromise between piezoelectric activity and maximum operating temperature, with rapid thermal degradation taking place at temperatures above 200ºC.
However, the new products are temperature-stable and rated for continuous use at up to 250ºC with an intermittent maximum of 300ºC. Available in tailored formulations, they boast piezoelectric charge coefficients (d33) exceeding 400pc/N.
