The invention relates to elastic surface wave pressure transducers. The invention has for its object a pressure transducer in which the plate is fixed by its periphery to a support having a central cavity in which a separating wall, forming an intermediate support, defines two chambers subject to the action of the pressures to be measured. The invention is more particularly applicable to the measurement of pressures and flow rates in the field of internal combustion engines.
