Pro Series Short-Wavelength Pyrometers
Short-Wavelengths Reduce Error From Emissivity Variations
For most applications, selecting the shortest practical wavelength is recommended. Shorter wavelengths result in smaller errors. In fact, short-wavelength sensors can be 4-20 times less sensitive to emissivity variation compared to long-wavelength sensors.
Short-Wavelengths Can View Through Optical Obstructions
Wavelength selection is a critical factor in Williamson’s short-wavelength technology. By choosing the correct wavelength span, you can view through water, steam,flames, combustion gasses, plasmas, and other common industrial interferences.
