The purpose of this investigation was to experimentally determine the performance characteristics of certain probe geometries and their respective locations in the sink tube of a pneumatic angular rate sensor. Sensor response was determined for various flow rates and angular velocities for each test condition. It was found that the pickoff element placed inside the sink tube yields a longer linear-response range than the one placed outside the sink tube. Use of one of the special flow dividing plates, with the probe located outside the sink tube, improves the linear-response range of the sensor for all flow rates, but increases the magnitude of the response only for the lower flow rates. It was also observed that neither the shortening of the sink tube length downstream of the pickoff location nor the presence of a shallow circumferential groove at the midsection of the pickoff element alters the performance of the probe.
