摘要： A system for measuring a multiplicity of pressures as those experienced by a model in a wind tunnel is depicted. The system includes individual sensor devices which are connected to an Acquisition and Compensation electronics module. The individual sensor or transducer devices are semiconductor piezoresistive devices and are connected to the Acquisition and Compensation electronics module by means of a cables in a first embodiment. In an alternate embodiment the system uses connectors which connect each of the individual sensor devices to the Acquisition and Compensation electronics module via a mating connector located therein. The connectors may also include a memory which stores compensation coefficients associated with each of the various sensor devices. In this manner as described, the transducers which are small devices are connected via electrical lines or cables to the central Acquisition and Compensation electronics modules. This module houses electronics which digitally converts the data from the sensors and then compensates the data for temperature effects. The advantage of the system is that each individual sensor does not have any compensation and it can be made very small to operate at very high temperatures without any loss of accuracy. Thus, a large number of sensors can be utilized in a very small volume, even under extreme environmental conditions. It is noted that the Acquisition and Compensation electronics module can be located remotely in a safe environment outside of the wind tunnel and therefore respond extremely accurately to the pressure and temperatures subjected by the model in the wind tunnel.

摘要： There is disclosed an internally switched multiple range transducer. The transducer employs a plurality of individual pressure sensors or Wheatstone bridges fabricated from semiconductor materials and utilizing piezoresistors. Each sensor is designed to accommodate accurately a given pressure range, therefore, each sensor is selected to provide an output when an applied pressure is within its accommodated range. As soon as the pressure exceeds the range, then another sensor is employed to produce an output. Each of the sensors, or each separate transducer, is coupled to a switch or other device to enable the selection of one of the plurality of sensors to operate within its given pressure range when the applied pressure is in that range. In this manner one obtains pressure measurements with a high degree of accuracy across a relatively large pressure range.

摘要： There is described a temperature compensation scheme for a pressure sensitive metal diaphragm transducer. The transducer employs a Wheatstone bridge fabricated from p-type piezoresistors. The Wheatstone bridge is glassed directly onto the metal diaphragm. As the temperature of operation increases, the diaphragm exhibits a temperature variation of the Modulus of Elasticity. The Modulus of the metal diaphragm decreases with increasing temperature. Because of this, the same pressure applied to the metal diaphragm causes it to deflect further, which in turns causes increased strain applied to the bridge. Because of this effect, the sensitivity of the transducer increases with increasing temperature. A resistor is now placed in series with the Wheatstone bridge. The resistor is in series with the biasing voltage and because the TCS of the diaphragm is of an opposite sign, the series resistor has an even higher TCR in series with the bridge. In this manner, the bridge voltage is made to decrease with increasing temperature. Due to the fact that the bridge voltage decreases with increasing temperature the change in voltage compensates for the change in the Modulus of the metal diaphragm and therefore provides an accurate output at all temperatures.
摘要翻译：描述了压敏金属隔膜换能器的温度补偿方案。传感器采用由p型压阻电阻制造的惠斯通电桥。惠斯通电桥直接在金属隔膜上玻璃化。随着操作温度的升高，隔膜呈现弹性模量的温度变化。金属隔膜的模量随着温度的升高而降低。因此，施加到金属隔膜上的相同压力导致其进一步偏转，这又导致施加到桥的应变增加。由于这种影响，传感器的灵敏度随着温度的升高而增加。电阻器现在与惠斯通电桥串联放置。电阻与偏置电压串联，并且由于隔膜的TCS具有相反的符号，所以串联电阻具有与桥连接的更高的TCR。以这种方式，使电桥电压随着温度的升高而降低。由于桥接电压随着温度升高而降低，所以电压的变化补偿了金属隔膜的模量的变化，因此在所有的温度下提供了精确的输出。

摘要： A pressure transducer, particularly adapted to measure the pressure in a tire and to enable the tire to be filled includes a first housing, having an internal hollow. Positioned in the hollow of the first housing is a second housing, also having an internal hollow. The second housing is supported within the first housing so that a passageway for airflow exists between the housings. The second housing has a pressure port for monitoring the pressure of a tire. The first housing has an inlet port for receiving a source of pressure. The inlet port contains a valve which is selectively operated. The valve, when operated, permits air to flow into the hollow of the first housing and to flow about the periphery of the second housing to enter the pressure port associated with the second housing. The pressure port may, as indicated, be associated with a tire and the second housing contains a pressure sensing device which monitors the pressure in the tire via the pressure port. In this manner, the pressure in the tire can be monitored while additional air can be added through the valve which air flows around the second housing to enter the tire or other device coupled to the pressure transducer.

摘要： A filter assembly for use with a static-dynamic piezoresistive pressure transducer that measures low amplitude, dynamic pressure perturbations superimposed on top of a high static pressure through the implementation of a low-pass mechanical filter assembly is disclosed. The filter assembly may comprise a dual lumen reference tube and a removable filter subassembly further comprising a porous metal filter and narrow diameter tube. The transducer, which may be capable of operating at ultra-high temperatures and in harsh environments, may comprise of a static piezoresistive pressure sensor, which measures the large pressures on the order of 200 psi and greater, and an ultrasensitive, dynamic piezoresistive pressure sensor which may capture small, high frequency pressure oscillations on the order of a few psi or less. The filter assembly may transmit static pressure to the back of the dynamic pressure sensor to cancel out the static pressure present at the front of the sensor while keeping dynamic pressure from reaching the back of the sensor. In this manner, the filter assembly enables the transducer to accurately read dynamic pressure in the presence of high static pressure without rupturing the thin diaphragm of the dynamic pressure sensor.

摘要： Disclosed is a novel flexible transducer structure suitable for attaching to curved surface such as the leading edge of an aircraft wing. The structure comprises a thin flexible sheet of an insulating material with a leadless transducer secured to the sheet. The sheet is then placed over the curved surface and assumes the curvature of the surface. The transducer secured to the sheet provides an output of pressure according the pressure exerted on the sheet. The sheet basically is fabricated from a thin material such as Kapton and is flexible so as to assume the curvature of the surface with the transducer being exposed to pressure applied to the curved surface. The sensor in conjunction with the flexible sheet allows pressure to be measured without disturbing the air flow patterns of the measuring surfaces and because of its construction, is moisture resistant over a large variety of atmospheric conditions.
