A capacitive pressure transducer comprising a pair of thin discs made from an insulator, a thin metal film metalized onto each of the discs and forming the plates of the capacitor, and means for bonding the two discs together such that the two metal films are opposite each other, the two metal films are separated by an open gap, and the two metal films are insulated one from the other. When pressure is applied to the discs, the discs are displaced thereby changing the capacitance of the pressure transducer.
