Technical data

10.1

Specifications

Accuracy

± 0.5%

Accuracy subject to: On factory approved installations, the weighfeeder system's totalized weight

will be within the specified accuracy when compared to a known weighed material test sample.

The test rate must be within the specified range of the design capacity, and held constant for the

duration of the test. The minimum material test sample must be equivalent to a sample obtained at

the test flow rate for three revolutions of the belt, or at least ten minutes running time, whichever is

greater.
