Installation Overview
When choosing a mounting method, both the advantages and disadvantages of each technique should be closely considered. Characteristics such as location, ruggedness, amplitude range, accessibility, temperature and portability may be extremely critical. However, often times the most important and overlooked consideration is the affect the mounting technique will have on the high frequency operating range of the accelerometer.
Shown below are six possible mounting techniques and their affect on the response of a typical piezoelectric accelerometer. (Note that not all of the mounting methods may apply to your particular sensor.) By examining the mounting configurations and corresponding graph, it can be seen that the high frequency response of the accelerometer may be compromised as mass is added to the system and/or the mounting stiffness is reduced. 
Note: The low frequency response is unaffected by the mounting technique. This roll-off behavior is typically fixed by the built-in sensor electronics. However, when operating AC coupled signal conditioners with readout devices that have an input impedance of less than 1 megohm, the low frequency range may be affected. |
