Abstract

An investigation is made of the resistance and capacitance temperature sensitivity of a Zn/orange dye aqueous solution/carbon cell. In this cell, a solution of 3 wt.% orange dye (C17H17N5O2) in distilled water is used as the electrolyte and zinc and carbon rods serve as electrodes. The cell is fabricated in organic glass box and has a height, width and thickness of 35, 30 and 14 mm, respectively. The resistance and capacitance–temperature studies are made in the interval of 35-80 °C. It is found that the resistance and capacitance of the cell depend on temperature: temperature sensitivity of the cell was -1.2%/°C and 1.5%/°C for the resistance and capacitance respectively. The Zn/orange dye aqueous solution/ carbon cell can be used as solution based resistive and capacitive temperature sensor..
