Thermography in Process Automation - Isabellenhuette

Heat is one of the most important parameters for weal and woe during production processes and for product quality. Therefore, measuring heat has always had major relevance which is reflected by the early use of temperature sensors during the automation of production processes. Now the fast visualization of temperature distributions with non-contacting infrared thermography allows even more complex automated solutions without using contacted temperature sensors.

Infrared camera
VarioCAM® series

The company Isabellenhütte Heusler GmbH & Co. KG has identified this potential at an early stage and uses infrared thermography for the quality assurance of their low resistance precision resistors. In this application the stationary camera of the VarioCAM® series proves its very high measuring accuracy. Temperature differences of only 35 mK can be detected. Besides this excellent thermal resolution also the possibility to securely measure smallest details provides an essential measuring basis for further automation. This is achieved by a higher detector resolution of (384 x 288) Infrared Pixels, a special close-up focussing as well as by close-up and microscopic lenses.

Furthermore Mr. Dobener of the company Isabellenhütte Heusler GmbH & Co. KG particularly appreciates the very easy integration of the VarioCAM® series into the production facilities. That applies for both the mechanics of the camera that stands out with its compact and rugged design and for the data interface with a speed of up to 60 frames per second. The matching functionality of the software development kit supports the precise control of the camera. The trigger ports of the thermographic camera allow for the direct synchronization with the control software of the measuring device. All measuring data are fully issued digitally in real time. Thereby the production facilities can respond even to smallest temperature variations in order to always keep the products of the company Isabellenhütte Heusler GmbH & Co. KG at the very highest level.

InfraTec thermography - Thermal resolution

Thermal Resol­u­tion – Determ­in­a­tion of Differ­ences of Only a Few Millikelvin

For detection of small temperature changes InfraTec's infrared cameras offer thermal resolutions up to < 15 mK in real-time operation. By using the Lock-in Thermography method it is possible to further increase this resolution significantly. For this purpose test objects are periodically excited and non-destructively examined for defects and irregularities.

InfraTec Service - thermography lenses

High‐performance Full Optics

High quality precision lenses allow the adaptation of the image geometry to almost every measuring situation. Its performance parameters are calibrated with respect to functionality, quality and flexible application. Due to proper IR-transparent lens materials and high-precision antireflexion coating, the lenses are optimised for different spectral ranges.

Integ­rated Trigger / Process Inter­face and Inter­faces – Digit­ally Controlling of a Infrared Camera and External Devices

The internal trigger interface guarantees highly precise, repeatable triggering. Each of the two configurable digital inputs and outputs are used to control the camera or to generate digital control signals for external devices. In this way, for example, the operation of a printed circuit board and the interval of a measurement can be synchronised.

The selection of different camera interfaces allows the processing of analog data, such as the voltage directly through the camera and thus the insertion of this information into the thermal image data. Relevant variables can be included in the evaluations with the software, which makes it easier to draw conclusions about the causes of temperature changes.
