本特利振动监测培训教程，本教程的主要内容：位移传感器噪声源
噪声是一种你不需要的信号，但多数情况下，在测量过程中，噪声是无法避免的。尽管在测量过程中无法除噪声，但可以将噪声降低到Z小程度，使其不影响你对信号的分析。要做到这一点，就要了解噪声的来源和特征。噪声是一种不合乎需要的信号成分，它可以歪曲数据，妨碍你从数据中提取机器状态信息的能力，包含的信息与机器的状态无关。噪声可以从测量系统的一个环节引入振动信号，但系统各个部分对噪声的敏感程度不同。本特利位移传感器包括bently3300系列的涡流传感器探头。

Bentley vibration monitoring training course, the main content of this course: displacement sensor noise source
Noise is a signal you don't need, but in most cases, noise is unavoidable in the measurement process. Although the noise cannot be removed during the measurement, the noise can be reduced to a small degree of Z so that it does not affect your signal analysis. To achieve this, it is necessary to understand the source and characteristics of noise. Noise is an undesirable signal component, which can distort data and hinder your ability to extract machine state information from data. The information contained is independent of the machine state. Noise can be introduced from0ne part of the measurement system, but each part of the system has different sensitivity to noise. Bently displacement sensor includes Bently 3300 series eddy current sensor probe.
