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 process, the noise can be reduced to a small level Z so that it will not affect your analysis of the signal. To do 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 the data. The information contained is irrelevant to the state of the machine. Noise can be introduced into the vibration signal from one part of the measurement system, but each part of the system has different sensitivity to noise. Bently displacement sensors include Bently 3300 series eddy current sensor probes.
Noise source of displacement sensor
1. Installation: vibration of sensor support 5. Runout - Mechanical deviation
Noise source of displacement sensor
Runout – electrical deviation: alloy elements are non-uniform, conductivity is non-uniform, magnetic conductivity is non-uniform, local stress of the material is concentrated, and there is local magnetization area on the axis
Noise source of displacement sensor
Runout and run time – short time mechanical and electrical deviations are stable
Noise source of displacement sensor
Runout and running time - the noise source of displacement sensor when thermal and process parameters change in medium time
Runout and running time – some noise sources (rust, corrosion, local magnetization zone, etc.) change for a long time
