Glue-on instructions
1.
Bolt end finish for the transducer should be
minimum of Ra 0.8 micro-meters.
Clean the end of the bolt with Loctite cleaner
or eq.
2.
Place a small amount of glue in the centre at
end of the bolt using brush/cocktail sticks or
similar device. For normal bolts use Loctite
620 or equivalent. For bolts to be used in high
temperatures, use Loctite 638 or equivalent.
3.
Place the transducer on the glue, align the
transducer at the centre. Use a pin or a pair of
tweezers. Then press the transducer down
towards the bolt. Alternatively, one can use
scotch tape and place transducer on the glue-
side of the tape for easier application of glue
and later placing onto bolt.
4.
Place a cover of plastic over the newly glued
transducer, place a magnet or weight on top of
it to let it harden. Leave for 5-10 minutes and
remove plastic.
5.
The bolt is now ready.
