便携式振动激振器，可提供峰值正弦力达60N(13.5lbf)。4809型是小型部件振动测试或现场实验模态分析的理想解决方案。
4809 型
台式振动激振器为包括机械阻抗和机械导纳测量以及加速度计校准在内的一系列应用提供了多功能性和可靠性。
4809型具有宽频率范围(10 Hz – 20 kHz)和8 mm(0.32 " ) 峰值连续位移。它可以传递45N（10 lbf）的正弦力 — 或与辅助风冷搭配高达60N（13.5 lbf）。
我们的 75 VA 2718型功率放大器专为驱动此振动激振器而设计；但是，4809型 也可以由具有适当额定电压的任何第三方放大器供电，而无需强制风冷。
为了满足您精确的测试需求，4809型可量身定制的一系列附件，包括耳轴、功率放大器、尼龙顶杆和推拉杆、传感器和阻抗头。
