    Abstract: A multi-range pressure sensor apparatus and method that provide multiple signal paths for detecting a broad range of pressures with a high accuracy. A pressure transducer can be configured to include the use of a pressure sense die with piezoresistive elements integrated into the sensor die and in a Wheatstone bridge configuration. A sensed output signal from the sense die can be transferred to one or more amplifier circuits. A programmable compensation circuit can be utilized to multiplex different amplified output signals from each of the amplifier circuits and to provide a digital output. A memory associated with the programmable compensation circuit provides separate compensations, which are stored for each of the different signal paths and removes errors due to amplifier gain and offset.

    Abstract: A gas gauge proximity sensor supplying gas in a reverse flow direction from the injection chamber to the measurement chamber. Supplying gas in a reverse flow direction enables the transient behavior in the sensor to more rapidly stabilize, with a resulting increase in bandwidth. Optionally, a scavenger chamber can be used to remove the excess gas by locating a scavenger aperture of the scavenger chamber in close proximity to the exit aperture of the injection chamber. A bridge proximity sensor can be used with a reference chamber to receive gas flow from a location close to the exit aperture of the injection chamber in order to reduce common mode errors.

  • Patent number: 7530274
    Abstract: A circuit produces an output that is proportional to the molar density of gas in a chamber. The circuit employs an operational amplifier which measures the temperature using a RTD or other element that changes resistance with temperature. The RTD is placed such that it produces a decreasing current draw at the inverting input of the operational amplifier as the temperature increases. This decreasing current draw in turn produces a decreasing voltage at the output of the operational amplifier. By changing the ratio of resistors connected to the non-inverting terminal of the operational amplifier one changes the offset of the output voltage. By changing the feedback resistor connected from the output of the operational amplifier to the inverting terminal and connecting the output of the inverting terminal to a voltage divider including the RTD device, one can change the gain with temperature.

  • Patent number: 7500300
    Abstract: A manufacturing method for a vacuum measuring cell provides first and second Al2O3 ceramic or sapphire housing bodies on opposite sides of an Al2O3 ceramic or sapphire membrane sealed to the bodies at its opposite peripheral edges. A reference vacuum chamber and a measuring vacuum chamber are on opposite sides of the membrane. An optical transparent window is provided in the first housing body and an optically reflective material is provided on a central region of the membrane. A lens is above the optical transparent window for optically linking to the optically reflective material on the membrane and an optical fiber outside the reference vacuum chamber and at a distance from the optical transparent window feeds light through the lens and window and in and out onto the optically reflective material on the membrane so that the level of membrane deflection is detected by a Fabry-Perot Interferometer.

  • Patent number: 7497124
    Abstract: A dual pressure sensor apparatus configured for attachment to a manifold includes a molded plastic housing with a body portion featuring an upper cavity, a measurement port, and a lower cavity closed by the manifold. First and second pressure sensor modules are mounted in first and second wells formed in the upper cavity, and electrically coupled to a set of leadframe terminals disposed in the upper cavity. An opening in the first well couples the first pressure sensor module to the measurement port, and an opening in the second well couples the second pressure sensor module to the lower cavity. The measurement port sealingly extends through an opening in the manifold so that the first pressure sensor module measures pressure in the manifold, and the body portion walls bounding the lower cavity are notched so that the second pressure sensor module measures atmospheric or barometric pressure outside the manifold.

  • Patent number: 7497125
    Abstract: A pressure sensor has a diaphragm with a first layer and a second layer, a pressure transmitting member being in contact with the second layer, and a sensing element. The diaphragm is deformable in response to a pressure applied on a front surface of the first layer. The transmitting member transmits this pressure to the sensing element. The sensing element detects the pressure. A heat applied to the diaphragm induces the layers to be shifted toward the transmitting member or the opposite side of the transmitting member due to a shape of the diaphragm. The layers of the diaphragm have thermal expansion coefficients differing from each other. A thermal deformation of the layers caused by the thermal expansion difference between the layers cancels out the thermal deformation of the layers originated in the shape of the diaphragm.

  • Patent number: 7490518
    Abstract: Systems and methods for digitally controlling sensors. In one embodiment, a digital controller for a capacitance diaphragm gauge is embedded in a digital signal processor (DSP). The controller receives digitized input from a sensor AFE via a variable gain module, a zero offset module and an analog-to-digital converter. The controller automatically calibrates the received input by adjusting the variable gain and zero offset modules. The controller also monitors and adjusts a heater assembly to maintain an appropriate temperature at the sensor. The controller utilizes a kernel module that allocates processing resources to the various tasks of a gauge controller module. The kernel module repetitively executes iterations of a loop, wherein in each iteration, all of a set of high priority tasks are performed and one of a set of lower priority tasks are performed. The controller module thereby provides sensor measurement output at precisely periodic intervals, while performing ancillary functions as well.

  • Patent number: 7477996
    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: 7464600
    Abstract: A transducer sensor is positioned within a hollow of the body of a housing. The housing has an extending alignment pin, which pin coacts with a corresponding slot or aperture in the wall of a vessel whose pressure or temperature is to be monitored. The transducer body is associated with a connector where the alignment pin is placed and extends from the housing in a fixed relation to the connector. A suitable aperture or slot in the wall of the vessel to be monitored accommodates the extending pin whereby when the transducer is placed in the vessel aperture the connector associated with the transducer is always located in proper position. Positioned on the housing is a sliding nut which can move in a direction parallel to the central axis of the housing and either to the right or left.
