Abstract
The application provides a differential pressure sensor and relates to the field of sensors.The differential pressure sensor comprises a core body provided with a conditioning circuit, the core body has multiple groups of high-low pressure stress concentration hole groups, any one group of high-low pressure stress concentration hole groups comprises two high pressure stress holes and two low pressure stress holes, the two high pressure stress holes and the two low pressure stress holes are plated with a thin film, and the thin film has a sensitive bridge.The differential pressure sensor can realize the functions that can only be realized by multiple traditional differential pressure sensors used in cooperation, reduces the requirements for installation space and installation difficulty, and saves cost.
