Williamson – Dual Wavelength (DW) Pyrometer

Vector CAG - Williamson Logo

Williamson is the only company that can offer two different ratio technologies: two-color and our unique dual-wavelength. Ratio pyrometers are different from single-wavelength pyrometers because they measure infrared energy at two wavelengths instead of one.

The ratio of energy between the two measured wavelengths is then converted into a temperature value. This method of measurement allows ratio industrial infrared pyrometer technology to compensate for emissivity variation, partially filled fields of view, and optical obstructions.

PRODUCT DESCRIPTION:

Dual-wavelength pyrometers use two separate and distinct wavelength sets on a filter wheel. Because the design allows for separate wavelengths, these wavelength sets can be independently selected and combined allowing for some unique capabilities.

  • Compensate for variable emissivity, temperature gradients, severe optical obstructions, and misalignment
  • Select wavelength sets tolerate water, steam, flames, combustion gasses, plasma, and laser energy
  • Separation of wavelengths produces a heavily weighted reading towards the hottest temperature viewed
  • Available in broad temperature spans and low-temperature ranges
  • Includes ESP filtering to continuously measure intermittent targets or eliminate intermittent interferences
  • Dual-wavelength pyrometers offer two different and selectable wavelengths allowing for all of the benefits of a two-color pyrometer plus some additional capabilities.
