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 •

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
