4393型是一种带侧面接头的压电式DeltaShear®, Unigain®加速度计。

4393型有用于输出的M3接口和用于安装的M3安装孔。 使用场景 高频率 重量轻 振动测试与分析 特点 这种压电式加速度计可作为电荷源。其灵敏度用电荷每单位加速度（pC/g）表示。 DeltaShear设计涉及三个压电元件和三个振块，它们排列在三角形中心柱周围的三角形配置中。该夹紧环对压电元件进行预加应力，以保证高线性度。在外壳和夹紧环之间收集电荷。使用的压电元件是PZ 23锆钛酸铅元件。外壳的材质为钛。 校准 在校准图中给出的灵敏度是在159.2Hz频率和10g加速度的情况下测量的。对于99.9%置信度，出厂校准精度为±2%。
