  • [IEEE 2018 26th Telecommunications Forum (TELFOR) - Belgrade, Serbia (2018.11.20-2018.11.21)] 2018 26th Telecommunications Forum (TELFOR) - Overview of Temperature Sensors for Temperature Measurement of PV Modules

    摘要： In this paper an overview of temperature sensors used for PV module temperature measurement is presented. Issues with contact temperature sensors, in the process of PV module temperature measurement, are explained in detail. Brief overview of related research is given, which includes analysis of measurement process and the presented results. Thorough research is conducted based on few commercially available temperature sensors, which include four contact and a single non-contact sensor. Measurement accuracy of all employed sensors was evaluated using a high-quality thermal imaging camera and the obtained measurement results are also presented.

  • Optical gas imaging with uncooled thermal imaging camera - impact of warm filters and elevated background temperature

    摘要： The goal of the presented study was to investigate the impact of warm filters and elevated background temperature on the operation of an uncooled wideband camera used for optical gas imaging (OGI). The Noise Equivalent Temperature Difference (NETD) parameter was measured for a VOx wideband OGI camera built for the purpose of the experiments, with and without an interference filter. The results demonstrate that warm filters have a clear effect on the performance of the OGI camera. Based on the standard NETD measurement procedures, a Camera-Scene Noise Equivalent Temperature Difference (CSNETD) parameter is proposed to quantify both the camera and scene noise. The CSNETD measurements are used to evaluate the impact of elevated background temperature on the performance of the OGI camera. Finally, the camera is used to image methane leaks in the MWIR and LWIR bands. The results are consistent with the presented NETD/CSNETD measurements and confirm the impact of warm filters and elevated background temperature on the operation of the uncooled thermal imaging camera.
