PRESSURE-DIFFERENCE WARNING SYSTEM

摘要

A pressure sensor (4) is adapted to measure pressure difference between the primary and secondary spatial regions. An energy supply device (14) is adapted to provide energy to operate a pressure difference warning system (2). An acoustic signal device (12) is adapted to output an acoustic signal if measured pressure difference exceeds specifiable threshold value. Independent claims are also included for the following: (A) a door with a pressure-difference warning system; (B) an aircraft with a pressure-difference warning system; (C) a method of generating an acoustic signal as a pressure-difference warning signal; (D) a computer-readable storage medium; and (E) a program element for generating an acoustic signal as a pressure-difference warning signal.
