ADVANCED DETECTION METHODS OF THERMAL FIELDS BY INFRARED IMAGING (BIM-30)
- It is a non-contact technique, therefore, it does not interfere with heat flow and, consequently, does not alter temperature measurement. It is possible to detect temperature even in areas not easily accessible.
- It has a very fast response, is in fact it is able to detect very fast thermal transients, typical of mechanical removal processes.
- It allows a fast scanning of the area to be analyzed (2D distribution of temperatures in the area under investigation, with the possibility of identifying thermal gradients),
- It allows temperature measurements with thermal resolutions of the order of tens of mK.
In recent years there is a growing interest in thermographic techniques in areas where requirements of quality, safety and durability are particularly stringent. However, their use is still limited by the shortage of valuable skills for carrying out surveys, for subsequent interpretation of results and proper tools.
Know-how developed by CETMA, allows monitoring, real-time and non-contact, of production lines in operation, reducing maintenance and downtime, giving possibility of taking preventive action, correcting process parameters which can lead to production of finished products of poor quality, if not properly calibrated. At the same time, know-how allows to perform a quality control on finished product, for a further optimization of production process. Know-how is also applicable in construction sector, in all those cases in which effectiveness of the process is closely related to adhesion between two materials (i.e. plaster - substrate, reinforcing material - substrate, etc.).
In contrast to already existing in market or in scientific literature (knowledge focused on a particular product or process), the exclusivity of know-how lies in the multidisciplinary applications (products and processes) and in the possibility to use numerical models for optimization of operating parameters (i.e. type of active / passive approach, type of heating source, acquisition frequency, heating time, technology used - pulsed thermography, lock-in, etc.) decreasing calibration and optimization time of control procedure for a specific application.
Thanks to this know-how, CETMA has skills and tools to define, depending on material, production process and sector of reference, optimal set of operating parameters for use of thermographic technique for quality control of products and process optimization.
Know-how is applicable to all engineering sectors, such as aerospace, automotive, construction, cultural heritage, leisure, furniture, energy efficiency, renewable energy, infrastructure, etc.
