7. Meter recalibration for
UK
non-standard belts
Measuring the tension of special belts with
extra thick backings, alternate materials, etc.,
F
may yield less than accurate results using unit
weights for standard belts. In these cases,
a simple calibration process may be used.
The belting can be placed on a fixture with
I
a known span length under various known
tensions (hanging weights can be used).
By taking frequency measurements at various
tensions, span frequency vs. tension data can
E
be collected. These data can then be used in
a graphical format or in equation form to
convert measured span vibration frequencies
to accurate belt tensions. Data of this type is
specific to each application and cannot be
NL
applied to drives with different span lengths.
Because the resulting data may not be linear,
it is best to measure the tension of non-
standard belts in terms of frequency rather
D
than deriving a new belt unit weight to measure
in terms of absolute tension.
