Abstract

A device for measuring a fluid pressure and for verifying the fluid pressure that has been measured comprises a sensor element having a fluid chamber and an element that adjoins said fluid chamber and can be deformed under fluid pressure, a resistance bridge being arranged on the deformable element side that faces away from said fluid chamber, for the purpose of generating a transverse bridge voltage dependent on said fluid pressure. The device also comprises a voltage divider which is connected in parallel to said resistance bridge for generating a differential voltage.
