devices are used to analyze the intensity of infrared rays naturally emitted by objects and then to visualize temperature distribution.
is not a new technique for on-line weld monitoring.
The main application of infrared thermography
in the civil sector lies in construction thermography.
The TVS-500EX will be showcased at the Infrared Thermography
Solution Seminar 2007 at the Tokyo International Forum on February 28, 2007.
The distribution of the surface temperature was recorded for each type of rotor during the cooling phase utilizing infrared thermography
. After a cooling time of five minutes, the HESC rotor had cooled down uniformly to a temperature at the surface of about 20-30[degrees]C/68-86[degrees]F, while the conventionally configured rotor cooled down unequally, with the heat retention greatest at places inside the wings, where the wall is very thick.
used in roof inspection is beneficial in reducing the number of hours spent on pinpointing areas that need repair; identifying leak areas before they become a major cause of property damage or mold; reducing total structure replacement; and assisting in nondestructive investigation.
Investments in infrared thermography
will return handsomely when used as part of a well-planned maintenance program.
The technique for making radiation visible is called thermal imaging or infrared thermography
