AccelerometerAccelerometers are a piezo-electronic (crystal) device. A pre- loaded crystal is charged with current and as the crystal is compressed or de-compressed by vibration an output proportional to g’s (gravity) is provided. A “g” is equal to 9.80 meters/second2 or one (1) standard earth gravity. Accelerometers are normally used for high-frequency bearing cap vibration readings (Case/Bearing …
Measurement Type Only measurements of the same type can be compared. Bearing Cap or Case Vibration cannot be directly compared to Shaft Relative or Shaft Absolute and visa versa.1). Case Absolute Case or Bearing Cap Absolute is the measurement of the Case or Bearings Caps (Location of Transducer) motion relative to free space (or absolute motion). …
