    Abstract: A method and apparatus integrates differential pressure measurements and absolute pressure measurements to provide a continuous absolute pressure profile over a wide range of pressures on a single integrated scale. The absolute pressure measurements and differential pressure measurements are obtained, and a correlation factor between the absolute pressure measurements and the differential pressure measurements is determined. The correlation factor is used to normalize the differential pressure measurements to virtual absolute pressure values on a common absolute pressure scale with the absolute pressure measurements. An absolute pressure profile over a wide pressure range includes the absolute pressure measurements in a portion of the range where the absolute pressure measurements are accurate, and it includes the virtual absolute pressure values in another portion of the range where the differential pressure measurements are accurate.

  • Patent number: 7921721
    Abstract: An oil-filled pressure transducer including a glass pre-form having contact pins and a oil-filled tube, each running top to bottom through holes in the pre-form. The oil-filled tube extends beyond the top of the pre-form. A glass alignment plate has an alignment aperture designed to fit over the extended oil-filled tube and-another aperture placed at a predetermined position from the alignment aperture which is shaped to accommodate a sensor. When the plate is aligned over the oil-filled tube, a sensor module can be positioned accurately in the alignment aperture so that contact is made with the pins. A header having a central diaphragm is placed over the pre-form and the aligned sensor creating a space between the diaphragm and the sensor which is filled with oil. The transducer utilizes less oil and exhibits a lower backpressure with increasing temperature than other oil-filled pressure transducers of similar size.
