High Precision Liquid Gas Steam Pressure Transmitter 3051

High Precision Good Stability Liquid Gas Steam 3051 Transmitter

3051 Transmitter Working Principle

NY3051 series intelligent differential pressure/pressure transmitter has a variable capacitance sensing component, called "δ" chamber (see the figure below), and the process pressure is transmitted to the "δ" chamber through the isolation diaphragm on both sides of the "δ" chamber and the filling liquid. The central diaphragm is a tensioned elastic element, which produces a corresponding deformation displacement for the pressure difference on both sides acting on it, and this displacement is transformed into a differential capacitor formed on the capacitor plate. The differential capacitance is converted into a standard output signal by the electronic circuit.
