Figure 11: The frequency response of an accelerometer can be greatly reduced when not using a
coupling fluid.
2) Adhesive
There are several different adhesives to consider when mounting your
accelerometer. Surprisingly though, the most important parameter for accelerometer
performance is not the adhesive type, rather it is the thickness of the adhesive that
plays the largest role. Figure 12 provides a few plots of the frequency response of
different adhesives (data is taken from that same Endevco presentation) which
illustrates what little difference there is.
