- Description
- Surface temperature measurement is applicable to a vast number of fields including manufacturing, processing, agricultural, medical and pharmaceutical fields just to name a few. Two methods for obtaining surface temperature measurements exist; ‘surface contact measurement’ in which the measuring device makes physical contact with the surface in question or alternatively, ‘non-contact surface measurement’ where there is no contact at all. Both of these methods have got advantages, as well as disadvantages. However, in recent times, non-contact methods have been preferred since they are non-intrusive and allow for remote measurements to be made. In this research, a non-contact mobile temperature measurement system is developed. The system is microcontroller-based and uses infrared sensors to acquire temperature measurements. The infrared sensors are mounted on a three-axes, x-y-z coordinate system which allows a thermal profile of a particular surface to be generated and displayed on a Graphical User Interface (GUI) in real-time. Various tests were carried out to compare contact and non-contact measurement methods; to determine the most suitable operating height for accurate non-contact measurement given a specific surface and to investigate the benefit of single and/ or multiple sensor arrangements. The research showed that a non-contact thermal scanning system could be used to obtain detailed yet accurate surface temperature measurements following an initial sensor calibration phase to determine the most favourable scanning parameters for a particular surface. The measurements taken could then be used to generate a thermal map of a surface with a significant improvement in resolution as compared with measurements taken using contact devices. The research further showed that a multiple sensor arrangement significantly reduced the time taken to generate the thermal profiles without undermining accuracy.
