  • Pressure sensor and pressure-measuring apparatus using pressure buffering
    Patent number: 6584854
    Abstract: A pressure-detecting chamber 23, a pressure-directing path 25 and a buffer space 24 are formed on the upper face of a main-body-side substrate 22 as recessed portions, and the upper face of the pressure-detecting chamber 23 is covered with a thin-type diaphragm 31, and upper faces of the pressure-directing path 25 and the buffer space 24 are covered with a cover substrate 30. A pressure-introducing unit 26 formed on the lower face of the main-body-side substrate 22 is connected to the lower face of the buffer space 24. The cross-section of the buffer space 24 is greater than the cross-section of the pressure-introducing unit 26, and the capacity of the buffer space 24 is greater than the capacity of the pressure-directing path 25.
