Advantages of Noncontact Thermal Measurement

The four most commonly stated advantages of noncontact thermal IR measurement over contact measurement are that it is nonintrusive, remote, much faster than conventional methods, and that it measures the temperature (or radiant thermal distribution) at the surface of the object of interest (we will call it the target), not the surrounding air. Any one, or a combination of, the following conditions warrant the consideration of a noncontact IR sensor  

When IR scanning and imaging systems are applied to solve temperature monitoring and control problems, another very powerful advantage is apparent the 

There are, of course, limitations to the noncontact approach—conditions that may make it impractical or ineffective. These will become apparent as the discussions progress.
