Testing Function
As piezoelectric transducers and ultrasonic motors expand into extreme aerospace, turbine, and nuclear power plant monitoring, assessing the thermal stability and depoling behavior of piezoelectric materials under real operating temperatures is paramount. Our PEMS-1000 in-situ testing system evaluates the longitudinal piezoelectric charge coefficient d33 directly under controlled mechanical preload across temperatures up to 700°C, recording thermal drift, structural phase transitions, and depoling thresholds in real time.
