An application of a commercially available and inexpensive pressure probe and transducer, originally designed for pressure drop measurements in air conditioning conduits, is suggested for accurate and reliable measurements of static pressure fluctuations in airflow, with a particular application to wind interaction with water waves. It is demonstrated that this static pressure probe is a robust...

A technique of recording the pressure apexcardiogram by means of a high-fidelity piezoresistive transducer has been developed in our laboratory. It permits the quantification of pressure with which the transducer is applied to the chest wall as well as the pressure changes during a cardiac cycle. In this preliminary report, apexcardiographic pressures were compared with simultaneously recorded ...

Extensive testing, at pressure "'evels from 3U to 758 MPa (5,000 to 110,000 PSI) was done at Aberdeen Proving Ground to evaluate 15 different types of electrical pressure transducers used in large caliber weapons. When using a given tvoe of transducer, the ability to consistently distinguish dynamic pressure variations as small as 0.2% was demonstrated. Yet different models of pressure transduc...

This article reports the development of a solid state pressure transducer for use in the measurement of blood pressure. It is intended to act as a replacement gauge for the mercury and aneroid manometers used in conventional sphygmomanometers. It measures pressure in the range 0-300mmHg (0-40kPa) with a resolution of 1mmHg (0.13kPa) and an accuracy of +1mmHg (+0.13kPa) which is displayed on a l...
