Enter width or number of ribs/strands
W = .
Capacity available for input is from 000.1 to
999.9 mm or number of ribs or strands.
For a synchronous belt, enter the width in
millimetres. For an Industrial V-belt, enter
the number of belts being measured.
For a Micro-V
For a Polyflex
the number of strands. Enter the number of
ribs/strands only for the belt being tested.
When using the Sonic Tension Meter on
drives with multiple single or PowerBand

the appropriate mass constant and enter
the correct number of belt strands being
measured. There is no need to multiply the
mass constant by the number of ribs/strands,
as the Sonic Tension Meter will calculate
the correct total belt mass.
Example:
For a V-belt drive using four individual SPB belts
enter "1" for the belt width ("Width" key).
The Sonic Tension Meter will display the static
belt tension per individual belt. When measuring
the belt tension in the V-belt drive, make sure
the V-belts do not interfere with each other
while vibrating.
If the same drive used a 4-strand SPB

"4" for the belt width ("Width" key). The total
belt tension for all four belts is measured as
the entire belt vibrates. The Sonic Tension Meter
will display the total static belt tension for the
PowerBand
Enter the span length
S =
Capacity available for input is from 0001 to
9999 mm. The span length represents
the distance between the contact points on
adjacent pulleys/sheaves. This distance may
be measured directly, or it may be calculated
from the formula below. Calculating the span
length gives the best results.
Span length (mm) = CD
Where:
CD = centre distance (mm)
D = large pulley diameter (mm)
d = small pulley diameter (mm)
Input data storage and retrieval
Weight, width and span values can be stored
for up to 40 different drive systems. Press the
"Select" key to toggle through the 40 storage
registers or press a number between 0 and 39,
then enter values for the belt constants.
After this is completed, the belt values can
be recalled for a drive by simply pressing
the "Select" key and the number that
corresponds to the storage register.
