| Research Abstract |
A fast response bi-luminophore pressure-sensitive dot array sensor has been developed on an anodized aluminum (AA) substrate for unsteady flow measurements. We have applied the isolated dot arrays of PSP and TSP formed on an AA substrate by an inkjet printing method to prevent interference between the two luminophores. Suitable solvent was chosen for each dye to form the dots with uniform and high luminescence intensity, and high sensitivity. The created bi-luminophore AA-PSP could simultaneously measure pressure and temperature and could reduce the temperature effect from 0.97 %/degree C (without temperature correction) to 0.02 %/degree C (with temperature correction). It showed a pressure response time of 64 micro sec at 90 % pressure rise to a step change of pressure, which is in the same range with a conventional AA-PSP.
