最多可达 48 个通道的同步光学振动测量
Polytec 公司生产的 MPV-800 多点式激光测振仪，最多可 48 个通道同时测量，并显示频率相关和时间相关的样品振型。光纤式光学头可自由配置，灵活测试，可将其平行布置于被测表面，也可将其布置在样品周围。
亮点
- 非接触式，在单个测量中同步获取瞬态和非稳态振动特性
- Capture transient and non-stationary events in a single synchronous measurement
- 灵活，用户可配置多达 48 个光学通道
- 时域和频域下的3D振型
- Non-contact vibration measurement
- 最佳光学灵敏度，无需表面处理
- 人眼安全激光
瞬间完成紧要复杂的测试任务
多点式激光测振仪可高精度完成紧要振动测量任务：
- 全场评估沉淀和衰变事件
- 非稳态过程（例如流体机械、阀门）
- 环境监测
- 电驱动装置和内燃机的启动过程
- 瞬态事件（例如冲击、开关）
Polytec MPV 软件可方便地配置所有通道（包括参考通道）和可选的信号发生器。为便于数据分析，将时域和频域下的振型和物体的3D几何形状叠加在一起。
MPV-800 多点式激光测振仪可非接触式测量轻质或热物体，特别是敏感或柔软表面。这些测量还包括生物医学应用，其中人眼安全的激光技术特别有益。
