High Quality Piezoelectricity Linear Actuator For Piezo Dispensing Valve - China

piezoelectric actuator, piezoelectric ceramic, Piezo Dispensing Valve Type: PSt150/7*7/x Material Properties

Material: PZT(PZT5H) Rel.

dielectric constant εref: 5400 Loss factor: 200*10-4 Coupling factor: KP=0.62, K31=0.34, K33=0.68 Piezo coefficient: d31=-290pm/V, d33=+635pm/V Elast.

compliance: S33E =18.1*10-12m²/N, S11E =14.8*10-12m²/N Frequency constant: Radial=2040m/sec, Thickness=1800m/sec, Transverse=1410m/sec, Longitudinal=1370m/sec Quality factor(resonance): 70 Density: 8g/cm³ Curie temperature: 150°C Specific heat: 380Ws/°K kg Thermal conductivity: ca.

1.5 Ws/m·K(axial direction) Above-mentioned parameters can vary significantly with the operating electrical field strength.

Temperature

Operating temperature: -50~+100°C(according to resin).

If >100°C, PZT performance will be reduced reversibly Above Curie temperature, piezo actuators will be permanently depolarized.
