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:
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
