Pressure Balance Cross-Calibration Method Using a Pressure Transducer as Transfer Standard

Shock-Tube Calibration of a Fast-Response Pressure Transducer

Impact of radial artery pressure waveform calibration on estimated central pressure using a transfer function approach.

Impact of Radial Artery Pressure Waveform Calibration on Estimated Central Pressure Using a Transfer Function Approach To the Editor: It is with great interest that we have read the excellent work of McEniery et al1 on the variability of the relation between central and brachial pulse pressure (pressure amplification), assessed in 10 000 subjects. We were, however, a little surprised about the ...

Subnanowatt Microbubble Pressure Transducer

We present the first all-Parylene microbubble pressure transducer (μBPT). The μBPT utilizes an electrolytically generated microbubble (μB), trapped in a Parylene microchamber, for pressure sensing. Pressure-induced bubble size variation is detected by electrochemical impedance measurement. Real-time hydrostatic pressure measurement with excellent sensitivity (-10.7 Ω/psi, ±0.1 psi) up to 1.8 ps...

Pressure transducer method for measuring gas production by microorganisms.

A simple method for measuring gas production by microorganisms by using a pressure transducer to sense pressure buildup was developed and tested with members of the coliform group. The test system consisted of a 5.0 lb/in(2) pressure transducer and a pressure equalizer valve attached to the metal cap of a test tube (20 by 150 mm); gas pressure was recorded on a strip-chart recorder. Gas pressur...

A Wide Temperature Range Pressure Transducer Having a Single Iteration Calibration Cycle

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...
