ADDITIONAL FEATURES
System Self-Diagnostics
The most important factor in the installation of
any weighing or controlling system is to assure
that all cables, I/O connections and options are set
up and working correctly. This can be very time
consuming and difficult, adding to the expense of
the installation.
Superior Free-Fall Control
The type of material being batched, ambient
temperature, flow rate, consistency of the material,
and many other factors impact the accuracy of
any batching process. The AD-4401 provides
two types of free fall compensation which may be
selected according to batching conditions. Fuzzy
The AD-4401 solves this problem by providing Free Fall Compensation is particularly effective
in batching inconsistent material, such as sand
