Infrared Thermography – A Smart Temperature Measurement Method with Enormous Potential

Infrared thermography is a passive imaging method for contactless temperature measurement. It uses the fact that every object with a temperature above absolute zero (-273.15 °C) emits electromagnetic radiation. The focal plane array infrared detector of the thermographic camera, which is equipped with individual elements arranged in a matrix, uses an optical system to capture the intensity distribution of the radiation emission from the measurement object over a large area. The camera converts the radiation intensities into measured temperature values for each individual pixel of the radiometric thermal image. This results not only in a few temperature readings from individual measurement points, as for example in the case of using thermocouples and pyrometers, but also in hundreds of thousands to millions of temperature readings that are completely distributed over the measurement object.

As a pyrometric optical temperature measurement method, thermography has a lot of special features that distinguishes it from conventional technical temperature measurement with contacting sensors: contactless, nonreactive thermographic temperature measurement can be conducted from a distance with very short response times. It can be used on moving measurement objects and can be used on live sources and encapsulated measurement objects behind protective windows. Lenses with different fields of view can be used to adapt to the geometry of the measurement object and the measurement points. This allows this temperature measurement method to be used for microscopic small details in the micrometer range as well as for objects that may be kilometres away.

In principle, thermographic cameras can measure object temperatures in a range from far below room temperature up to more than 3,000 °C with absolute accuracies in the percentage range. However, real measurement objects and measurement environments usually require a high degree of expertise and experience in design, setup and, if necessary, error compensation of thermographic measurement arrangements.

The visualization of images, also known as thermograms recorded by thermographic cameras, can be performed in different ways. Best known are gray value or so-called false colour representations, in which each temperature value is assigned a gray level or a certain colour. Therefore, the user can get a very clear overview of the temperature distribution on the measurement object and immediately detect anomalies such as hotspots and discontinuities, which can indicate hidden faults for example. Another important feature is the ability of thermographic cameras to depict rapid changes in temperature or temperature distributions: Thermographic sequences, which can be captured in full frame mode at frame rates of up to several hundred hertz and in subwindow modes up to several kilohertz, allow temporal resolutions down to the submillisecond range. This ability ensures the user to record temporal profiles of thermal processes in detail for a better understanding, and if necessary to optimise them.

A special field, the so-called active thermography is utilising these capabilities to make hidden defects in specimens like cracks, blowholes and delamination visible by the help of mainly artificial temperature changes in a non-destructive way.

Due to their modern variable interfaces, our thermographic cameras can be used easily for process optimisation and quality assurance in almost all fields of industrial metrology and image processing. Based on thermal images and sequences it becomes obvious if the manufacturing process is running within defined parameters or deviations will occur. As a result, product quality increases while costs decrease.

Easy Integration in a Direct Way

Regardless of the specific application, the decisive factor for OEM partners is, how easily the system can be integrated into the existing environment. InfraTec’s powerful SDK offers best conditions for a convenient integration:

  • Recording of real-time thermographic data in various adjustable formats (temperature data in Kelvin, 16-bit digital values, 32-bit bitmap, 8-bit data)
  • Real-time calculation of temperature values in °C as well as relevant characteristic values such as minimum, maximum, mean value and standard deviation
  • Operation, control and parameterisation of the thermographic camera via remote access
  • Optional connections for the development environments MathWorks, LabVIEW and MATLAB
  • Software development is being conducted at InfraTec's headquarters in Germany

Interfaces for Camera Control and Data Transmission

State-of-art interfaces enable reliable camera control and data acquisition even over very long distances. All InfraTec thermographic cameras are equipped with GigE Vision and industrial GigE compatible interfaces. Alternatively, 10 GigE interfaces can be used. These enable high-speed data transmission at ten times faster transmission speed. Fibre optic versions allow data transmission with high electromagnetic immunity and over extremely long distances in addition. Alternatively, CAMLink interfaces are available for ImageIR® models, too.

Depending on the respective camera model, the following interfaces can be selected:

  • 10 GigE / GigE
  • CAMLink / DualCAMLink

To ensure that the protection degree of the cameras is maintained even under harsh operating conditions, the connections at our VarioCAM® High Definition are equipped with LEMO® plug connectors that maintain that level of protection.

OEM Solutions from InfraTec - Protection housing

Reliable Protection Even in Harsh Industrial Environments

An indicator of a thermographic camera durability is always its housing. Therefore, InfraTec attaches great importance to high standards. Closed housings made of high-tensile aluminium alloys with a degree of protection up to IP67 guarantee such standards. Thus, the sensitive sensors and electronics remain protected at all times, even when used in harsh industrial environments.

Suitable protective housings, for example made of stainless steel, are available for applications under extreme environmental conditions. Optionally equipped with cooling and heating, certain models are also certified according to ATEX directives.
