Fig. 25: Select application
Mass flow (belt/spiral)
The application "Mass flow (belt/spiral)" is for the detection of the
mass flow of bulk solids on a conveyor belt or a conveyor spiral.
Mass flow summation slave
The application "Mass flow summation slave" is for the detection of
the mass flow of bulk solids, for example on a broader conveyor belt
with several instrument whereby the concerned instrument works as
a slave.
When you have selected this function, you can activate the slave out-
puts via a selection field. When you activate this field, then the current
output of WEIGHTRAC 31 functions.
When the output is activated, the instrument remains in its function as
a Slave, but the 4 … 20 mA output can be also used als single instru-
ment. The instrument provides the complete range of functions when
the output is active.
Information:
If you want to operate your instrument as master of a mass flow sum-
mation, select application "Mass flow (belt/spiral)".
In this window you can carry out the settings for the speed of the
conveyor belt or the spiral conveyor.
