Applied Measurements Ltd was asked to
design a batch weighing system where
the ingredients of each batch would
constantly vary. To weigh the batches
into the barrels AML built a stainless
steel weighing platform incorporating
load cells to the specific size
required by the customer. As the
barrels could be dropped on to the
weighing platform, positive overload
stops were included to protect the
load cells.
The output signal from the weighing
platform is fed into a digital display,
which has two set point relays.
Connected to the digital there is also
a touch screen display, this enables
the operator to see the live reading,
the batch reading, the total batches
and a numeric keypad to input the
individual batch size. The touch screen
controls the set point relays in the
digital display.

Also built into the control panel were
two further digital indicators
connected to PT100 temperature probes
monitoring two mixing vessels. The
complete system was set up to let the
batching control proceed, however if
one of the mixing vessels temperatures
went out of range the relays of the
digital indicators would cut the pumps
to the main mixing vessel. The operator
at a glance could see his two
temperature readings, his live weight
on the platform and he could have full
control of his batching.
The total flexibility of the touch
screen technology means that AML could
program the unit to suit the customer’s
requirements, including the customers
name and logo on screen. The use of
the touch screen technology enables
AML to offer a very cost effective
flexible process control system for a
diverse range of applications.
