  • Patent number: 10132705
    Abstract: Systems and methods are disclosed for a pressure sensor device. The pressure sensor device includes a header that defines an interior cavity including one or more tether connecting regions. The header further defines an outer portion in communication with the interior cavity; the outer portion includes a plurality of through bores in communication with an exterior portion of the header for insertion of header pins through the header. The pressure sensor device includes a pressure sensor chip disposed within the interior cavity of the header. One or more anchoring tethers are attached to the corresponding one or more tether connecting regions. The pressure sensor chip is free to move within the interior cavity of the header, and the one or more anchoring tethers are in communication with the pressure sensor chip and are configured to limit movement of the pressure sensor chip within the header.

  • Patent number: 9429491
    Abstract: Example embodiments of the disclosed technology methods, devices, and systems for compensating a sensor having thermal gradients. In one embodiment, a system is provided that includes a sensor, including a first half-bridge transducer configured to output a first pressure signal associated with a first received pressure; a first set of span resistors coupled to the first half-bridge transducer, and configured generate a first compensated pressure signal; a second half-bridge transducer, configured to output a second pressure signal associated with a second received pressure; and a second set of span resistors coupled to the second half-bridge transducer and configured to generate a second compensated pressure signal. The system includes an output port that is configured to output a signal associated with a difference between the first compensated pressure signal and the second compensated pressure signal.
