MC-AF-type semiconductor strain gauge
with coefficient sensitivity , small hysteresis, wide resistance range
and small transverse
effect characteristics . Mainly used to measure the stress distribution,
as well as a variety of sensors' force-electric conversion components.
Widely used in measuring static and dynamic to analysis the complicated
stress for machinery, electronics, aviation, shipbuilding, railway and
bridge engineering structures .

Note: AF-15, AF-60 strain gauge primarily as a foil sensor's linear
compensation.
Instruction
1．Treat composes
electric bridge's 4 strain gauge screening, the resistance number is as
close as possible to match the group to use .
2．Pastes the piece of the test sample to extend 45 degrees angles with
the 0# sandpaper to rub alternately, forms the crystal likely hairy
surface.
3．Uses the acetone in turn and the absolute ethyl alcohol to clean the
dirt on the pasted piece.
4．Uses the
sensor special-purpose paste rubber or 502 rubber according to the test
sample stipulation stress direction the strain gauge glue on the test
sample, attention control glue line thickness, take thin, reliable and
evenly suitable, the glue line should not have the residual air bubble .
5．If uses the sensor special-purpose paste rubber, must carry on
solidification processing strictly according to the corresponding
solidification craft.
6．If uses 502 rubber, according to 502 rubber characteristic air nature
solidifications.
7.
The glue line solidification finished then changes over to the next
technical process to carry on the group bridge, the compensation, the
test and so on .
