Abstract
A differential pressure transducer having a body of insulating material on which film electrodes are fixed, two diaphragms made of insulating material, and two film electrodes on the inner sides of the respective diaphragms facing the body. The diaphragms and the body together form cavities which are filled with an incompressible liquid, and the film electrodes of the body and of the diaphragms form capacitances which are dependent on the diaphragm deflection. The transducer is especially suitable for the measurement of the flow rate of explosive liquids or gasses.
