Technical systems must be regularly checked for defects, such as cracks. Up to now, piezo sensors measuring pressure, force or voltage have been used to reliably detect such faults – but only to around 200 degrees Celsius. Now, special high-temperature piezo sensors can continuously monitor components that are as hot as 900 degrees Celsius. Fraunhofer researchers will present their development at the SENSOR+TEST measurement fair in Nürnberg, May 30 to June 1, 2017.
