Acoustic emissions GENERAL DESCRIPTION
The ADXL1004 delivers ultralow noise density over an
extended frequency range and is optimized for bearing fault
detection and diagnostics. The ADXL1004 has typical noise
density of 125 µg/√Hz across the linear frequency range.
Microelectronicmechanical systems (MEMS) accelerometers
have stable and repeatable sensitivity, and are immune to
external shocks up to 10,000 g. Rev. 0 The integrated signal conditioning electronics enable such
features as full electrostatic self test (ST) and an overrange (OR) …
