  3. Traditional vs. Fiber-Optic Pyrometers

Fiber Optic Style

Williamson is the leading manufacturer of accurate non-contact temperature sensors or pyrometers. Fiber-optic pyrometers offer a distinct advantage over their traditional counterparts because of their ability to be used in tight areas and survive harsh environments.

Traditional Williamson pyrometers and their fiber-optic counterparts are very similar:

  • They use similar wavelength sets
  • They offer similar temperature spans within these wavelength sets

Traditional sensors and fiber optic sensors also have a few differences:

  • Traditional Style

    Fiber-optic models include an aim light for easy alignment and are better suited for use in hard to reach areas where it may be difficult to mount a traditional sensor because of mechanical obstructions

  • Fiber-optic models can be configured with a variety of different fiber-cable styles offering various levels of protection. Williamson can offer both quartz and glass fibers
  • The electronics within the pyrometer generally need to be placed in cooler areas as they can only withstand temperatures up to 140°F/60°C. If you are operating at elevated ambient temperatures a fiber-optic configuration would be preferable as the pyrometer housing can be placed in a cooler location and the fiber optic cable can operate at temperatures up to 400°F/200°C.

  • Traditional sensors offer higher/enhanced optical resolutions allowing them to make temperature readings of smaller target sizes
