J054023 Simultaneous pressure and temperature measurements by pressure and temperature-sensitive paints

Abstract

Pressure-Sensitive Paint (PSP) is a pressure sensor based on the oxygen quenching of the luminescence of luminophore. In general, the luminescent intensity of PSP depends not only on pressure but also on temperature. Therefore, it is necessary to simultaneously measure the temperature with the pressure to improve the accuracy of PSP measurement. The compound sensor composed of pressure and temperature-sensitive luminophore was developed for simultaneous measurements of pressure and temperature. However, some of such compound sensors suffer the degradation of the sensitivity and other properties. In this paper, we show the possibility of a compound PSP/TSP sensor using PtTFPP and CdSe/ZnS.
