Zusammenfassung:	PURPOSE:To provide a method and device for correcting a detected pressure value in a pressure sensor capable of confirming the detected pressure value regardless of pressure fluctuation by displaying the detected pressure value as a pressure difference from a standard pressure value according to the initial pressure fluctuation of a pneumatic apparatus in a pressure sensor for detecting fluid pressure by the output signal of a semiconductor pressure sensitive element. CONSTITUTION:The output signal of a semiconductor pressure sensitive element 1 is converted 2 into a pressure value, a standard pressure value is stored in a memory means 4 by a timing signal generated according to the initial pressure fluctuation of a pneumatic apparatus, and the pressure difference between the detected pressure value and the standard pressure value is calculated 5 and displayed on a display means 6.
