V-RMS and Temperature metrics of the ball bearing units of an industrial blower

Sensor devices were attached to the two mounted ball bearing units of an industrial blower and collected v-rms and temperature measurements throughout several months of operation. The v-rms is a vibration metric representing the average velocity of the bearings' vibrations and here is expressed in <em>inch/sec</em>, while the temperature is a self explanatory metric and is expressed in degrees of <em>Fahrenheit</em>. The data were collected during a normal and an encumbered operational production period and were used for the training and evaluation of an Autoencoder model for the purpose of predictive maintenance and the task of anomaly detection.本数据集将传感器装置安装至某工业鼓风机的两台预装式滚珠轴承单元上，在长达数月的运行周期内采集v-rms与温度测量数据。其中v-rms为表征轴承振动平均速度的振动指标，单位为英寸每秒（inch/sec）；温度指标含义直观，单位为华氏度（Fahrenheit）。本次数据采集覆盖了正常运行与受限生产运行阶段，所获数据被用于自编码器（Autoencoder）模型的训练与评估，以支撑预测性维护与异常检测任务。
