CA80
PREPARING THE SG INSTALLATION

CA80 can also be applied to smooth or polished areas if the surface of the
measurement object must not be damaged.
The steps described below should be taken immediately after roughening to prevent the
formation of new oxide films.
4.5 Fine cleaning
Carefully remove all dirt particles and dust.
u
To do this, dip a pad of non-woven material using clean tweezers into one of the
solvents mentioned above and then clean the measuring point.
u
Only ever make a single stroke with each non-woven pad.
u
Continue cleaning until there is no discoloration (contamination) on the non-woven
pad. Make sure that the solvent has evaporated completely before taking any of the
following steps.
4.6 Preparing non-metallic bonding surfaces
Non-metallic materials are basically treated in the same way as metals. The bonding sur­
faces must be free from grease and, if possible, slightly roughened. Polyethylene and
untreated fluoropolymer cannot be bonded.
We generally recommend carrying out tests beforehand to check bonding capability. You
do not need to roughen the surfaces of glass, porcelain or enamel.
Important
Do not use your breath to blow away any fluff that remains or touch the measuring point
with your fingers after cleaning under any circumstances!
5 PREPARING THE SG INSTALLATION
Important
Because CA80 adhesive has such a short reaction time, the strain gage can no longer be
aligned once the bonding process has been started. Therefore, be sure to follow the
instructions below.
When the SG has a lead, the solder terminal can be attached with the SG to the workpiece
in a single operation.
u
First, remove residual oxide from the soldering eyelets using an eraser pencil or
similar.
u
Then slide the solder terminal between the lead and the carrier of the SG.
