Preparation
Attachment of an acceleration pickup
There are some methods of attachment to the measurement subject of Accelerometer.
Contact resonance frequency * changes with the attachment methods of an Accelerometer
sharply.
Please perform suitable attachment in consideration of the advantage and fault of each
attachment method
*Contact resonant frequency and the high region characteristic
If an Accelerometer is attached in a measurement subject, one vibration system will be
formed and the peculiar resonance frequency of the system will be decided.
This is called contact resonance frequency.
Contact resonant frequency is boiled variously and changes with the fixed method of
Accelerometer and measurement subject, or contact states.
A lower figure shows change of the high region characteristic by the attachment
method. Therefore, the suitable attachment method of Accelerometer is chosen, and in
order to remove the influence of Contact resonant frequency further, it is necessary to
choose the frequency range.

An example of change that high frequency response by the Accelerometer attachment
method is shown below.
