摘要： The system for active regulation of the air/gas ratio of a burner comprises one or two differential pressure measuring systems each of which has a differential pressure sensor with two inlet orifices. The orifices are respectively connected to pressure ports in one of which there is a calibrated throttling orifice. The regulator system comprises a 2-channel valve which, when closed, isolates the two inlet orifices from each other, and, when open, connects them to each other. A measurement circuit is provided and has memory means for storing at least two values of the output signal of the sensors, a control unit for switching the valve and controlling the storage of a first value of an output signal of the sensor in the memory means when the valve is closed and the storage of a second value of the output signal of the sensor when the valve is open, and subtractor means for calculating the difference between the two stored values of the output signal of the sensor and thereby eliminating any drift. In a preferred variant, the regulator system includes only one differential pressure measuring system.

摘要： A pressure sensor operates on the principle of a differential pair of capacitors having a movable plate that is constituted by the deformable membrane of the sensor. It comprises a measurement circuit for measuring the capacitance of the capacitor, which circuit is incorporated in the housing of the sensor and is made up of first and second double-sided interconnected circuits which are situated on either side of the membrane and which are connected thereto in its peripheral region by connection means. The faces of the circuits which face the membrane serve to mount respective stationary plates of the capacitor, and the faces of the circuits which face away from the membrane comprise respective regions on which components that are sensitive to the displacement of the membrane towards one or other of the fixed plates are mounted, and a region that is insensitive to stray capacitance is also provided on one of the faces that face away from the membrane, for receiving the components forming the remainder of the measurement circuit.
