1. FEATURES OF F805AT-BC (BELT SCALE TYPE)

1-1. Basic Functions

F805AT-BC (Belt scale type) provides accurate metering of materials while they are
being conveyed on the belt conveyer. Using weight signal from the load cell and
velocity signal from the speed sensor installed on the conveyer system, the following
data items can be obtained through mathematical calculations:
① belt speed
⑤ feed ratio
Velocity detector
(rotary encoder)

1-2. Control Functions

Velocity detector
(rotary encoder)
Using the speed signal from the rotary encoder and the weight signal from the load cell
as shown in the figures, the feeder can be controlled to maintain a constant flow, or feed
rate (continuous feed rate operation). Another possible control method is to operate the
feeder so that the total increases linearly with time (continuous total operation).
