摘要： Techniques disclosed herein include systems and methods for pressure measurement of fluids including vehicular fluids. The pressure sensor includes a microelectromechanical system (MEMS) sensor for pressure measurement. The MEMS sensor is attached to a glass tube which is compressively sealed to a mounting frame that is attachable to a pressure port of a fluid-containing enclosure. Techniques disclosed herein provide an hermetic seal between the tube and the mounting frame and a rigid seal between the MEMS sensor to a pressure sensor while decoupling thermal expansion stress from the MEMS sensor. With such decoupling techniques, pressure sensing reliability and accuracy can be improved because thermal expansion stress is decoupled from the MEMS sensor. Such techniques provide an accurate, durable, and cost-effective pressure sensor.

摘要： Techniques disclosed herein include systems and methods for pressure measurement of fluids including vehicular fluids. The pressure sensor includes a MEMS die for pressure measurement. The MEMS die is attached to a glass pedestal member. The pedestal member is mechanically held in place via a mounting frame that attachable to a pressure port of a fluid-containing enclosure. Techniques herein provide a strong connection of a MEMS die to a pressure sensor while decoupling thermal expansion stress from the MEMS die. With such decoupling techniques, pressure sensing reliability and accuracy can be improved. With thermal expansion stress decoupled from the MEMS die, sensor sealing materials can be selected for their robust chemical properties instead of structural properties. Such techniques provide an accurate, durable, and cost-effective pressure sensor.
