Wide network for drawing
machines
The AUTAC 250S system provides a
reliable, fast, non-contact temperature
measurement, control and display for
preheating or post-annealing in
extrusion or wire drawing applications.
The non-contact principle offers a long
life span and accurate measuring results
without danger of marring the product.
A closed loop control to the preheater of
the wire temperature guarantees better
product uniformity and a uniform
bonding of the insulation. By mounting
the sensor close to the extruder, any
heat loss occurring between the
preheater and the extruder can
automatically be compensated for.
AUTAC 250S can also be connected to
Zumbach’s universal USYS processors
and be used as a stand-alone
temperature measuring and control
system. An integrated SIGMA Expert
controller can be interfaced to a
preheater or to a post-annealing station
in order to keep the material temperature
on target at all times.
The technical advantages of the system
are said to include:
A slotted design, so no threading •
required
Fast response time •
Compact •
Unaffected by air draught •
Wire break protection •
Immunity to dirt •
Main data:
Product diameter range: •
0.32mm–6mm (0.012–0.24")
