PSC-SR54NL/PSC-SR54NV Two-Color Non-Contact Infrared Pyrometers
PSC-SR54NL and PSC-SR54NV
2-Color Pyrometer Series For Industrial and R&D Applications
PSC-SR54NL/PSC-SR54NV Non-Contact Infrared Pyrometers Description
Two-Color or Ratio Pyrometers measure temperatures from the ratio of radiation signals of two adjacent wavelengths as opposed to measuring the absolute intensity within one wavelength, as with one-color pyrometers. The advantages and benefi ts of using two-color sensors are the following:
• Automatic compensation for viewing though dirty windows, dust and partial smoke between sensor and target.
• Compensation for changes in target emissivity i.e. gray bodies — targets with the same emissivity on both wavelengths.
• Measures smaller target than sensor’s fi eld of view (FOV/Spot Size) i.e. measures weighted peak temperature within FOV.
• Unaffected by moving targets within FOV.
