Applications
The950MDwasoriginallydesignedforuseinsteel
millapplicationsbuthasproventobereliableinmany
applicationswhereruggedness,environmentalprotection
andeaseofmountingarerequired.Someofthese
applicationsinclude:
Steel Mills-Tundishcar(Tundishheight),turret
height(Caster),hydrauliccoilcars,torchcutoffmachine
(torchheadmonitoring),furnacetilt,electrodepositioning,
sideguidepositioning,ladleslidegatepositioning,louver
orroofposition,etc.

compactors,furnaceorovendoorsandmaterialtransfer
systems.
Injection Molding and Die Casting–Proveneffective
inmonitoring/controllingthepositionoftheclampand/
orshotcylinder.Thetwopointconnectionofthe950MD
housingallowsforasimpleretrotbyreplacinglimit

entirerangemovement.Linearpotentiometerscanalso
bereplaced,thuseliminatingtheirproblemswithdrift,
temperature,andshortlifespan.
