  • Page 8: Operating Conditions

    -3 to 3 0.01 The YO Vibration Monitor is a device with an external port for connecting a vibration module which is equipped with a high precision accelerometer and temperature sensor. The device reads accelerometer data for the X, Y and Z axes and then processes the data to obtain the specific physical measurements used to track vibrations in motors.
  • Page 9 YO Vibration Monitor User guide v1.0 page 9/36 RMS g refers to the measurement of root mean square (RMS) acceleration values along three perpendicular axes: X, Y, and Z. This measurement is commonly used in vibration analysis to quantify the overall intensity of vibrations in different directions.
  • Page 10 YO Vibration Monitor User guide v1.0 page 10/36 RMS Velocity refers to the measurement of root mean square (RMS) velocity values along three perpendicular axes: X, Y, and Z. This measurement is crucial in vibration analysis to assess the effective vibrational energy in different directions.
  • Page 11 YO Vibration Monitor User guide v1.0 page 11/36 Crest Factor refers to the ratio of the peak value to the RMS (Root Mean Square) value of vibration signals measured along three perpendicular axes: X, Y, and Z. This metric is important in vibration analysis to assess the severity of peak events relative to the overall vibration level in different directions.

  • Page 12: Temperature And Relative Humidity

    YO Vibration Monitor User guide v1.0 page 12/36 Kurtosis refers to the measurement of the "tailedness" or extremity of the distribution of vibration signals along three perpendicular axes: X, Y, and Z. This metric is critical in vibration analysis to assess the presence of outliers and the propensity for extreme values in different directions.
  • Page 13 YO Vibration Monitor User guide v1.0 page 13/36 External temperature measurement plays a crucial role in vibration monitoring of electric motors, providing valuable insights into the operational health and condition of the motor.
