How it works

The NP3051 series intelligent differential pressure transmitter has a variable capacitance sensing component, called the "δ" chamber (see the figure below). The process pressure is transmitted to the center diaphragm of the "8" chamber through the isolation diaphragms on both sides of the "8" chamber and the filling fluid. The center diaphragm is a tensioned elastic element, which produces a corresponding deformation displacement for the pressure difference on both sides acting on it. This displacement is converted into a differential capacitance formed on the capacitor plate. The electronic circuit converts the differential capacitance into a standard output signal.
