Abstract

This paper presents the development of a wireless detector specifically designed for weathering test chambers, which are employed to assess the effects of solar radiation on various materials. Accurate evaluation of internal irradiance parameters within these chambers is critical for precise analysis. However, the absence of detection windows in many chambers poses a challenge to the measurement process. To address this limitation, a wireless detector is introduced, overcoming structural and operational constraints. Existing wired radiometers are unsuitable for the high-temperature conditions inside the chambers, while the few available wireless options fail to meet measurement requirements and stability criteria. The proposed wireless calibration apparatus incorporates national calibration standards and wireless transmission technology to enable real-time measurement of irradiance. It comprises a wireless calibration module, a handheld terminal, and a PC terminal. Finite element simulation analysis is utilized to investigate temperature rise and distribution within the aging test chamber, thereby informing the design of temperature control systems. Furthermore, this paper explores the shell design of the wireless calibration device, emphasizing circuit board protection. Overall, the proposed wireless detector and calibration apparatus overcome the limitations associated with existing wired and wireless radiometers, offering a more accessible and accurate solution for weathering test chambers.
