A Wide Temperature Range Pressure Transducer Having a Single Iteration Calibration Cycle
نویسنده
چکیده
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 liquid crystal display. It operates from a 9V PP3 battery over a temperature range of -10 to +60 o C. It is fully temperature compensated and can be calibrated in a single temperature cycle. Key-Words:Pressure Transducer, Electronic Manometer, Blood Pressure Measurement, Sphygmomanometers, Temperature Compensation.

Nanogap Pirani Sensor Operating in Constant Temperature Mode for Near Atmospheric Pressure Measurements
This paper presents a high sensitive micro-sensor designed for pressure measurements in a wide range around atmospheric pressure, for application in aerodynamics. The sensor is a temperature-resistance transducer operating with the Pirani effect, which states that below a certain pressure limit, the thermal conductivity of a gas is pressure-dependent. The sensor presents a wide measurement rang...
متن کاملNonlinear derating of high-intensity focused ultrasound beams using Gaussian modal sums.
A method is introduced for using measurements made in water of the nonlinear acoustic pressure field produced by a high-intensity focused ultrasound transducer to compute the acoustic pressure and temperature rise in a tissue medium. The acoustic pressure harmonics generated by nonlinear propagation are represented as a sum of modes having a Gaussian functional dependence in the radial directio...

متن کاملDetection of Coherent Terahertz Radiation from a High-Temperature Superconductor Josephson Junction by a Semiconductor Quantum-Dot Detector
We examine the application of Josephson radiation emitters to spectral calibration of single-photonresolving detectors. Josephson junctions are patterned in a YBCO film on a bicrystal sapphire substrate and are voltage controlled to generate radiation in the frequency range of 0.05–1 THz. The detector used in this work consists of a gate-defined quantum-dot photon-to-charge transducer coupled t...
متن کاملTwo efficient methods for measuring hydrophone frequency response in the 100 kHz to 2 MHz range
As new medical applications of ultrasound emerge with operating frequencies in the hundreds of kilohertz to low megahertz region, it becomes more important to have convenient calibration methods for hydrophones in this frequency range. Furthermore, short diagnostic ultrasound pulses affected by finite amplitude distortion require that the hydrophone frequency response be known well below the ce...
