A differential pressure measuring device () comprising a housing () having two pressure areas () which are sealed relative to each other and are separated from each other by a membrane (). The membrane () comprises a pressure plate () surrounded by an elastic circumferential area () allowing axial movement of the pressure plate (). An indicator element () is permanently connected to the pressure plate () and whose position can be evaluated in a non-contact manner by a sensor (). At least one pair of springs () is provided, with one spring () each of said pair of springs being located in an allocated pressure area (). Each spring () of said pair of springs () exerts an opposing spring force on the pressure plate ().
