Abstract
The design and calibration of a unique thin unsteady pressure sensor for use on small-scale marine propellers is presented. The Polyvinylidene Fluoride film-based sensor incorporates a miniature interface circuit suitable for use where space is a premium. Sensitivity of the sensor is comparable to high-quality microphones. Calibration is performed using an acoustic source and an industry-standard microphone. Evaluation of the sensor’s performance is presented for white noise unsteady pressure input. Results show excellent agreement between sensor-measured pressures and standard microphone-measured pressures.
