Thermal Imaging Cameras from Fluke

  • Uncategorized

Localized heating problems can be difficult to detect without proper equipment. An electrical component may look fine externally but there may be a small spot that is reaching temperatures above its normal rating. If not detected early, the electrical component may fail without warning. To help find heating problems easily, technicians use thermal imaging devices. These tools sense infrared radiation and convert it to visible light. This allows technicians to “see” hot spots that are not normally visible through the naked eye. The temperature difference is represented as various colors. This allows the technician to exactly determine how hot a surface is.

Thermal imaging cameras are not only suitable for electrical preventive maintenance but also for real-time operational analysis of machinery, research and development, observation of processes to ensure safe and efficient operation and electronic design. 

If you are thinking of getting a thermal imager, you might be interested in the Fluke Ti32 or Ti55. These thermal imagers offer excellent sensitivity and rugged operation. If you are undecided on what model to choose, read on for a comparison of features.
