Abstract
A resonant pressure transducer, having a deformable diaphragm or membrane exposed to an ambient environment wherein a pressure force to be measured exists, is provided. A transducer according to the present invention comprises a converter for transmitting the pressure force experienced by the diaphragm to a resonator vibrated by an exciter whose resonant frequency is a function of the intensity of the ambient pressure force to be determined. The converter and resonator are mounted in a rigid frame. The converter has flexible bending means able to absorb the bending moments resulting from the deformation of the diaphragm, so as to transmit to the resonator a tension or a compression force free from bending moments that generate stresses at the entrance of the resonator.
