Temperature Application Highlights

Induction, resistance, and flame heating systems are often used to accelerate heating rates for faster processing or to localize heating to a targeted area. With a rapid heating capability, precise temperature control is critical to achieve consistent quality results. Many systems are controlled based on time, power, and other factors, but when accuracy and repeatability are critical, infrared sensors are used for direct temperature measurement and control. When selecting a sensor, accuracy, response time, alignment, and durability are all important considerations. With flame applications, selection of the sensor wavelength is also critical.

Solution
Williamson's dual-wavelength sensors provide unequalled performance for induction, resistance, and flame heating applications. These high-performance sensors provide automatic alignment to the hottest temperature viewed as well as effective compensation for variations in emissivity, dirty optics, quench fluids, and surface oxidation or scale. Fiber optic sensors are often used for alignment with difficult to access targets, and a bifurcated fiber cable option can enable the measurement of two areas with one sensor.

For low temperature, low emissivity applications, Williamson offers innovative short-wavelength, single-wavelength sensors. The Auto Null design provides unequalled performance for these difficult applications.
