TSM Control Systems of
Dundalk in Ireland is using
HBM’s single point load cells
to ensure high accuracy in its
range of weigh blending
systems. These measure a
recipe of different plastic
granules by weight and blend
the resulting mix so that it
can be used in different types
of plastic processing.

TSM’s machines vary in
capacity from a maximum
batch weight of 0.5kg in the
smallest system to 32kg in
the largest. Larger machines
can take up to 12 different
material components to
make the final mixture.Most
have a single HBM SP4M
load cell but some of the
larger models have two units.

Michael McKiernan, TSM
design engineer, says: “We
like the open construction of
the SP4 load cells since there
are no guards. This prevents
granules from getting lodged
around the load cells.”
