A flexible transducer structure suitable for attaching to a curved surface such as the leading edge of an aircraft wing is provided. In one example embodiment, a method may include receiving, at a sensor disposed on a flexible sheet, a pressure, wherein the sensor is electrically coupled to a conductive trace disposed on the flexible sheet; measuring, by the sensor, the pressure to generate a pressure signal; outputting, by the sensor, to the conductive trace, the pressure signal, wherein the conductive trace extends away from the sensor on the flexible sheet; and wherein the flexible sheet is adaptable to conform to a contour of a curved surface.

There is disclosed a high temperature pressure sensing system which includes a SOI, silicon carbide, or gallium nitride Wheatstone bridge including piezoresistors. The bridge provides an output which is applied to an analog to digital converter also fabricated using SOI, silicon carbide, or gallium nitride materials. 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, silicon carbide, or gallium nitride materials and which memory stores various data indicative of the microprocessor also enabling the microprocessor test and system test to be performed.

In one embodiment, a method includes receiving, at a first diaphragm, a first pressure, wherein the first diaphragm is composed of metal; transferring, from the first diaphragm, to a first sensor, the first pressure using a first oil region, wherein the first oil region is disposed between the first diaphragm and the first sensor; receiving, at the first sensor, the first pressure; measuring, by the first sensor, the first pressure to generate a first pressure signal; and outputting, from the first sensor, to a first header pin, the first pressure signal, wherein the first header pin is electrically coupled to the first sensor using a first conductive glass frit.

Systems and methods for an internally switched multiple range transducer are provided. In one embodiment, a method comprises receiving, at a first sensor, a pressure, wherein the first sensor is associated with a first pressure range; measuring, at the first sensor, the pressure to generate a first pressure signal; in response to determining that the first pressure signal is not associated with the first pressure range, activating a second sensor, wherein the second sensor is associated with a second pressure range that is different from the first pressure range; and measuring, at the second sensor, the pressure to generate a second pressure signal.

Internally switched multiple range transducers

Exemplary embodiments of the present invention provide a differential pressure transducer that comprises first and second diaphragms of different configurations, i.e., different diameters and/or thicknesses. The pressure transducer provides more versatility over prior art designs as the diaphragms can be of different configurations yet still maintain substantially similar back pressures. Therefore, the errors commonly associated with back pressures are eliminated because the back pressures from the diaphragms ultimately cancel out in the sensor's differential pressure measurement.

A wireless interface system that interfaces with any one of a plurality of transducers of different types, such as pressure sensors, temperature sensors, and current probes. The transducers employ identical connectors with a common connecting scheme. In this manner, any transducer can be connected to a wireless interface which has the same input connection scheme. When the wireless interface is connected to the transducer, a rechargeable battery, which is associated with the wireless interface, is activated. The wireless interface then determines the type of transducer being utilized and provides sufficient circuitry as well as determining the requirements of the connected transducer. In this manner, the wireless interface, besides recognizing and determining the type of transducer, can determine the range of the sensor and can provide specific circuitry to be activated to supply power and to read data from the sensor via common output pins.
