Adhesive Stud Mount Procedure
Adhesive mounting is often used for temporary installation or when the machine surface cannot be adequately
prepared for stud mounting. Adhesives like hot glue or wax work well for temporary mounts; two-part epoxies and
quick –bonding gels provide a more permanent mount.
Note: Adhesively mounted sensors often exhibit a reduction in high-frequency range. Generally, smooth surfaces
and stiff adhesvies provide the best frequency response.
This method involves attaching a base to the machine surface, then securing the snesor to the base. This alows
for easy removal of the accelerometer.
STEP 1 Prepare a smooth, flat mounting surface. A minimum surface finish of 63 µin [0.0016 mm] generally
works best.
STEP 2 Stud-mount the sensor to the appropriate adhesive mounting base according to the guidelines set forth in
Steps 2 and 3 of the Standard Stud Mount Procedure.
STEP 3 Place a small portion of adhesive on the underside of the mounting base. Firmly press down on the
assembly to displace any extra adhesive remaining under the base.
