A dash is a value TRS does not publish for that grade.
The highest sensitivity TRS publishes: d33 of 780 pm/V and a dielectric constant of 6800, at a Curie point of 150 °C.
Piezoelectric coefficient 780 pm/V
Type VI soft PZT with the highest shear response in the catalogue — d15 of 983 pm/V and k15 of 0.76.
Piezoelectric coefficient 750 pm/V
General-purpose Navy Type II soft PZT: balanced coupling and sensitivity at a 340 °C Curie point.
Piezoelectric coefficient 400 pm/V
The most thermally stable soft grade, with the highest coercive field and Curie point of the Type II set.
Piezoelectric coefficient 300 pm/V
Type II soft PZT tuned for higher sensitivity than TRS 200 while holding a 370 °C Curie point.
Piezoelectric coefficient 450 pm/V
