描述：

Bently 190501 CT Velomitor 速度传感器是标准 Velomitor 压电速度传感器的低频版本。其设计专门测量冷却塔和风冷热交换器风扇组件的外壳振动速度，这些组件的运行速度为 90 rpm 或以上（典型值为 100 至 300 rpm）。Velomitor CT 传感器可以测量这些频率下的振动幅度以及风扇电机和减速器产生的振动频率。

Description:

The Bently 190501 CT Velomitor speed sensor is a low-frequency version of the standard Velomitor piezoelectric speed sensor. It is designed specifically to measure the vibration speed of the housing of cooling tower and wind cooling heat exchanger fan assemblies that operate at 90 rpm or more (typical values are 100 to 300 rpm). The Velomitor CT sensor measures vibration amplitude at these frequencies as well as vibration frequencies generated by fan motors and retarders.
