Development of a Full Operational Capacitive Pressure Sensor

Abstract

<div class="htmlview paragraph">Pressure is always a crucial measure in experimental aerodynamics. There are many ways of measuring pressure and nowadays methods that allow integration to computers are preferred. The objective of this paper is to present the development and construction of a full functional displacement capacitive sensor for measuring dynamic pressure by adapting conventional U manometers. The development of the sensor was made low cost and yet presents a fair precision. Experimental data are presented. The sensor is intended to be equipped in the CEA's (Centro de Estudos Aeronáuticos) wind tunnel located in Belo Horizonte (MG).</div>
