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.

The bridge provides an output which is applied to an analog to digital converter also fabricated using SOI technology. The output of the analog to digital converter is applied to microprocessor, which microprocessor processes the data or output of the bridge to produce a digital output indicative of bridge value. The microprocessor also receives an output from another analog to digital converter indicative of the temperature of the bridge as monitored by a span resistor coupled to the bridge. The microprocessor has a separate memory coupled thereto which is also fabricated from SOI technology and which memory stores various data indicative of the microprocessor also enabling the microprocessor test and system test to be performed.

摘要： There is disclosed apparatus for measuring multiple pressures within different pressure ranges. The apparatus contains multiple pressure sensors which are positioned on a housing, where each pressure sensor is adapted to measure pressure within a different pressure range. The housing has an input port which is constructed to communicate with different output ports, where the output ports communicate with each different pressure sensor utilized in a different pressure range. The input port has a stepped or keyed aperture which is adapted to receive different pressure adapters to assure that, for example, only a high pressure will be applied to the high pressure sensor during high pressure measurements. By selecting another adapter, a mid-range pressure and a high pressure will be applied to the pressure sensors during the measurement of a mid-range pressure. By receiving a different adapter, a low pressure will be applied to all the pressure sensors during low pressure measurement. In this manner, one is assured that the pressure sensors are operated without damage to the diaphragms during all pressure measurements. It is of course noted that while three pressure ranges are indicated, there can be more than three or at least two pressure ranges can be accommodated within the common housing. As indicated, the common housing has an input port which consists of contiguous varying diameter sections to enable the selective insertion of various adapter members as indicated where each adapter member can only be inserted within the input port to a desired position, where at that position, the pressure applied to the input port will be directed to the proper sensor.

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： It is an objective of the present invention to provide a pressure transducer assembly for measuring pressures in high temperature environments that employs an elongated tube which is terminated at one end by an acoustic micro-filter. The micro-filter has a plurality of apertures extending from one end to the other end, each aperture is of a small diameter as compared to the diameter of the transducer and the damper operates to absorb acoustic waves impinging on it with limited or no reflection. To improve the absorption of acoustic waves, the elongated tube may be tapered and/or mounted to a support block and further convoluted to reduce the overall size and mass of the device. A pressure transducer with a diaphragm flush may be mounted to the elongated tube and extend through to the inner wall of the tube. Hot gases propagate through the elongated tube and their corresponding pressures are measured by the transducer. The acoustic filter operates to absorb acoustic waves resultant from the hot gases, therefore enabling the pressure transducer to be mainly responsive to high frequency waves associated with the gas turbine operation.
