GATES SONIC TENSION METER MANUAL
7. METER RECALIBRATION FOR
NON-STANDARD BELTS
Measuring the tension of special belts with extra
thick backings, alternate materials, etc., 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 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 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 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 than deriving a new belt
unit weight to measure in terms of absolute tension.
