PICMA压电陶瓷促动器带来超长使用寿命
PICMA压电陶瓷促动器为全瓷绝缘。这可以防潮,避免漏电流增大造成故障。PICMA促动器的使用寿命比传统 的聚合物绝缘促动器长达十倍。它们被证明可实现无故障运行1000亿个循环。
适用于复杂真空应用
压电陶瓷促动器无需润滑,不会造成磨损。全瓷绝缘PICMA促动器也不需要聚合物绝缘,因此非常适合真空应用。

Integrated sensor: Versions with SGS allow closed-loop linearity up to 0.15 % and are shipped with calibration log.
Stiffness in Z: Static large-signal stiffness; dynamic small-signal stiffness is approx. 30 % higher.
The resolution of the system is only limited by the noise of the amplifier and measuring technology because PI piezo actuators are free of friction.
