Abstract
A pressure sensor with calibration device includes a casing, a diaphragm, a sensing element, a medium, and at least one calibration element. The diaphragm is disposed on the casing, wherein the casing and the diaphragm define an accommodating space. The sensing element is disposed in the casing. The medium is filled in the accommodating space and in contact with the sensing element. The at least one calibration element is adjustably disposed at the casing and extended into the accommodating space to be in contact with the medium, wherein when the at least one calibration element is moved relative to the casing in a direction toward the accommodating space or in a direction away from the accommodating space, the at least one calibration element changes the pressure applied to the medium. The pressure sensor with calibration device adjusts the pressure value sensed by the sensing element via the calibration element.
