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.
