Abstract
In Aerospace applications, transient pressure measurement in harsh environment using strain gauge type of pressure sensor, suffers due to the limitations of strain gauges and contact transduction method. In this paper, a novel pressure sensor using eddy current principle has been proposed with complete design to overcome the challenges faced by the other type of pressure sensors in harsh environment. Unlike magnet based transduction, the designed pressure sensor does not require recalibration after every use as the target will not loose its properties for short duration of high temperature exposure. The performance evaluation of the designed sensor supported by simulated test results is presented for analysis and improvement. Further scope of work towards improvement of accuracy, bandwidth and miniaturization has been concluded to aid sensor design in future.
