Thermography
Two Minute Tips
Safety in Thermal Imaging
Across the world the approach to safety is quite varied, and one can easily become complacent if you do not take a wider view of it. In many forums, regardless of the engineering discipline or matter of social interest, there will be varying views about what is acceptable in terms of safety or what should be common knowledge.

Infrared Thermography as a Diagnostic Tool for Roofing Systems
Thermography is typically used for condition assessment and forensic studies, as well as quality assurance inspections of new installations, repairs, and retrofits. Performed properly, thermography can provide valuable insights into the condition of a roofing system by graphically documenting the extent and location of subsurface moisture within a roof..

Nine Steps to Setting Up an Infrared Inspection Program
Infrared inspections are now a matter of routine for many commercial and industrial facilities. By proactively addressing incipient or latent failures detected during a single inspection, facility managers are able to avoid costs associated with unscheduled downtime and damage to electrical and mechanical equipment. Even greater savings can be achieved through...

What Are An Arc Flash & Arc Blast
An Arc Flash is an energy discharge of light and heat that forms when a fault occurs in an electrical circuit. The arcing results in a tremendous amount of energy being released as current flowing through ionized air. An Arc Blast, separate from an Arc Flash, is a supersonic shockwave produced when the uncontrolled arc vaporizes the metal conductors.

Mechanical Infrared Opportunities
While infrared is one of the most versatile of condition monitoring tools, we often fail to utilize it to its full potential. We know infrared is a key technology for all levels of electrical applications but when establishing condition monitoring programs, we may not realize what a great support technology it is for a variety of mechanical applications....

Is That a “Real Hot Spot” or Just a Reflection?
So much emphasis is placed on emissivity that in many cases reflectivity is not given the respect and attention it deserves. When capturing high-quality infrared data, reflected or background energy must be known, along with an understanding of how it is influencing the image and data.
