WILLIAMSON CORP.

On-line and/or portable infrared thermometers provide noncontact temperature measurement of thin plastic films, plastic extrudates, coatings, molded parts, and plastics in virtually all types of processes. Instruments for all purposes, from occasional spot-checking of temperature to complete on-line process temperature-control systems.

Difficult temperature measurements, such as on tenter frames for extremely thin films, are readily accomplished using thermometers employing highly precise, extremely narrow-band infrared filters. This technique enables device to accurately measure surface temperature of film without looking through the film or being influenced by the background.

Monitoring and controlling temperatures during heating in infrared or hot-oil ovens is possible by actually measuring product temperature itself, rather than attempting to infer its temperature, using secondary techniques like measuring air or heater temperatures to estimate product temperature.
