What is the standard of IR?

IR is generally understood to encompass wavelengths from around 1 millimeter (300 GHz) to the nominal red edge of the visible spectrum, around 700 nanometers (430 THz).

What is the purpose of thermographic test?

Thermography is a non-destructive testing method used to detect and measure small temperature differences to help find deterioration in assets and plant sites. Thermography can support the maintenance of industrial plants and equipment with its fast and cost-effective application.

What would an advantage of thermographic inspection be?

Inspections using infrared thermography will help in detecting problems and allow for repairs. This will mean fewer downtimes, a factor that will, in turn, result in fewer interruptions.

How do you test a thermography?

The most accurate thermographic inspection device is a thermal imaging camera, which produces a 2-dimensional thermal picture of an area showing heat leakage.

What is thermographic equipment?

The thermographic equipment in question is an infrared camera comparable in size to a video camera. Whereas a standard video camera responds to visible light radiating from the object in view, thermographic units responds to the object’s infrared radiation.

What is thermography in condition monitoring?

Thermography can be used to identify and analyze thermal anomalies for the purposes of condition monitoring of machines. These thermal anomalies are usually caused by such mechanisms as operation, improper lubrication, misalignment, worn components or mechanical loading anomalies.

How accurate is thermography?

The accuracy of thermography was obviously lower than that of mammography (69.7% vs. 76.9%). The sensitivity of the combined imaging package was higher than that of each imaging (96.2% vs. 80.5% and 81.6%), but the specificity and accuracy became lower.

What is qualitative thermography?

Qualitative Thermography For some applications, the operator only needs a thermograph, or infrared data represented as a visual image, to interpret the scene and identify the source of a problem or the need for a repair. This qualitative method of thermography provides the visual cue necessary to act.

What is Thermography in maintenance?

Infrared thermographic testing detects thermal waves that are invisible to the naked eye. It can aid in predictive maintenance by using data about temperature fluctuations to identify potential maintenance issues that might lead to equipment failure and shutdown.

Where is most heat lost from a house?

Heat escape routes The roof and windows are the hottest, showing that most heat is lost from the house through those parts. Heat energy is transferred from homes by conduction through the walls, floor, roof and windows. It is also transferred from homes by convection .
