Temperature Application Highlights

The typical thin wire process involves a small and moving metal target that is heated to obtain specific material properties. With each process, accurate temperature measurement and control is critical to efficiently produce a consistent quality wire product. The small diameter and motion of the target create unique challenges for any temperature control system, but with Williamson’s innovative capabilities and the proper selection of the sensor optics, it is possible to obtain accurate and repeatable results on wires smaller than .001 in (.0254 mm).

Solution
Williamson’s dual-wavelength sensors provide unequalled performance for temperature measurement and control on wire applications. These high-performance sensors provide automatic alignment to the hottest temperature viewed as well as effective compensation for variations in emissivity, dirty optics, and surface scale. A relatively large sensor target area  also allows the wire to wander in the process without leaving the sensor’s field of view.

For low temperature, low emissivity applications, Williamson offers innovative short-wavelength, single-wavelength sensors with an Auto Null design that provides unequalled performance for these difficult applications. With these installations small spot optics or fiber optics are used to insure that the sensor’s field of view is completely filled by the measured target.
