How do I mount an accelerometer?
The mounting of an accelerometer affects its frequency response.
The mounted natural frequency is dependent directly on the
stiffness of the mounting. The higher the stiffness the more the
mounted natural frequency approaches its maximum. The least stiff
mounting of an accelerometer is magnetic mounting and the highest
stiffness is using a high tensile setscrew tightened to the correct
torque mounted on a hard flat surface. Other mounting methods come
in between these two extremes.
It is important to ensure that the site chosen for the
accelerometer is ground flat for at least an area larger than the
base of the accelerometer. A slight smear of Silicone grease will
ensure a stiff bond between accelerometer and structure.
When using a mounting stud it is important to ensure that the stud
does not bottom out in either the base of the accelerometer or the
drilled location hole. High tensile strength set screws that have a
shoulder will prevent this eventuality from happening.
