２ . Overview, note, and checking item in defective measurement
The sonic belt tension meter (U-507) enables non-contact,
simple, and accurate measurement of installation tension
which is greatly related to belt function by analyzing sonic
wave. Sonic wave is generated by flipping the belt span with the
belt standing still, and it is captured by the sensor and
processed by high performance computer, and belt tension is
displayed in digital mode.
