Document Type and Number:
Japanese Patent JP7420022
Kind Code:
B2
Abstract:
[Problem] To provide a pressure sensor which reduces the influence that temperature distribution on a membrane has on pressure detection values. [Solution] Provided is a pressure sensor including: a membrane in which distortion corresponding to pressure occurs; at least two first resistors disposed apart from each other on a first circumference of said membrane, on which positive distortion characteristics are observed when pressure is applied; and at least two second resistors disposed apart from each other on a second circumference of said membrane, on which negative distortion characteristics are observed when pressure is applied. A Wheatstone bridge that includes the at least two first resistors and the at least two second resistors is formed; and at least either the number of first resistors disposed on the first circumference or the number of second resistors disposed on the second circumference is three or more.
