Frequency range of IIS3DWB vibration sensor for velocity?

[JTam.1]

Hi, what is the frequency range of IIS3DWB vibration sensor for velocity? Thanks!

[TBomb.1]

For an harmonic motion (and for a generalized motion as well), the maximum frequency for the acceleration is the same as the velocity one.

For the IIS3DWB case, the maximum ODR is 26.67kHz, but the flat frequency response range is from DC to 6 kHz (±3 dB point) as stated in the datasheet, so 6kHz is also the maximum detectable frequency for the velocity.

Hello @Community member​ ,

ISM330DLC - 3D accelerometer, How to check the over limit vibrations?

Configured the sensor ISM330DLC - ODR set to max 6.6KHz (which is max limit for chip).

If sensor ISM330DLC is exposed for heavy vibrations in the range above 3.3kHZ, for example 4kHz.

Is there a way that sensor provides any information or register update to indicate to the user that vibration is over limited?

Please assist to solve the issue.

Regards,
