Abstract
In this paper, a high temperature plastic film type water level sensor was developed. The high temperature film type water level sensor was manufactured by attaching a copper film to a polyimide film which can be used for a long time at 250℃, by laminating process and patterning the electrode by etching process. For the performance evaluation of the developed film type water level sensor, the temperature dependence of the capacitance was measured, and the deformation was examined after standing for 8 hours in 150℃ air. The developed film type water level sensor can be used at up to 150℃, and can be applied to electric ports and steam devices.
