ADHESIVE MOUNTING
Practically all accelerometers lend themselves to be adhesively
bonded to an object. Temporary bonds can be achieved with many
different tacky adhesives, beeswax, or cyanoacrylate type cements
(such as Krazy Glue)
.
These types of bonds are easily peeled off
or broken off in shear. More permanent bonds can be achieved
with two part epoxy adhesives. Refer to Table II above f or a list of
recommended adhesives
.
Notice that there are many other good,
permanent, two part
adhesives which
may be used f or
accelerometer bonding
.
Further note that the durability of the
adhesive is quite often better for slow curing adhesives that it is for
fast curing types.
