The total thickness from the base of the transducer
to the material density boundary (typically the
back-wall) is measured. Suitable for measurement
of materials between 0.63mm and 500mm (0.025"
to 19.999") thick.
A coating of up to 2.0mm (0.08") thick is ignored
and the material thickness from the top surface of
the material to the material density boundary
(typically the back-wall) is measured. Suitable for
measurement of materials between 2.54mm and
20mm (0.100" to 0.787") thick.
