Adhesive Mounting
To avoid damaging the accelerometer during subsequent removal, it is recommended to use an
adhesive mounting adaptor for this method of attachment. For adhesively mounting of accelerometers
the following guidelines should be followed:
The mounting surface should be clean and free of any residue or foreign material.
The mounting surface should be smooth, flat, and with a maximum surface roughness of 64 micro-
inches rms.
For best high frequency performance a cyanoacrylate adhesive is recommend. A thin layer offers
best frequency response.
Soften adhesive cured adhesive with a chemical debonder (eg. acetone) prior to removal. Gently
shear accelerometer loose from the mounting surface after waiting a few minutes for the debonding
agent to penetrate the epoxy. Make sure not to use excessive force as this may damage the
accelerometer.
Biaxial Mounting Configurations
The model 4623 accelerometer has a unique housing that enables it to be mounted in two different
orientations to measure either the normal or transverse acceleration input. By simply rotating the housing
90 degrees, the accelerometer can now be used to measure transverse motion. The two mounting
orientations are illustrated below.
