Williamson – Two-Color (TC) Pyrometer
$1.00
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.
Two-color pyrometers use what is called a “sandwich detector” using a fixed set of wavelengths, meaning that two wavelength filters are laid one on top of the other.
One wavelength is a broad waveband (0.7-1.1um for example) and the other wavelength is a narrow waveband (1.0-1.1) that is a subset of the broader band.
- General purpose wavelength set
- Can tolerate modest optical obstructions, misalignment and partial field of view
- Compensate for variable emissivity
- Used when there is a clear optical path between the pyrometer and target
- Can only measure temperatures above 1100°F / 600°C
- Keep in mind that two-color pyrometers cannot view through common optical interferences, so it is critical to avoid water, steam, flames, combustion gasses, plasma and laser energy for the most accurate and repeatable results.
