Abstract (en)
[origin: WO2016042247A1] The invention relates to a device for measuring differential pressure, comprising a first pressure measurement means (11) which measures a first pressure value (P1) and a second pressure measurement means (12) which measures a second pressure value (P2), the second pressure measurement means (12) being configured to read the pressure (P1) measured by the first measurement means (11), to calculate the pressure difference between the pressure (P1) measured by the first pressure measurement means (11) and the pressure (P2) measured by the second pressure measurement means (12), and to transmit the pressure difference value in the form of a single signal. The first pressure measurement means (11) is of the analogue or digital type, the second pressure measurement means (12) is of the digital type, and the transmitted differential pressure value is in the form of a single digital signal.
