FIELD: physics.
SUBSTANCE: at the first stage of manufacture preparation of component parts and assemblies takes place that is manufacture of an armour ring of spring steel, of a ring nozzle with a conic external facet of a tungsten alloy, a titanium hexagonal foundation and a cup-type body with a coaxial connector or a cable. The second stage involves fixation of the assembly in the vertical axial fixture of the electroerosion wire-cutting machine-tool, making three vertical grooves in fixed positions, mounting sensor elements, press-fitting or hot shrink fit of the armour ring on the ring nozzle with piezoelectric elements, making horizontal radial sections under the armour ring for an inertial mass formation and installation and fixation of the body and connection to the outlet of the preliminary amplifier of the connector.
EFFECT: invention allows to use in the transducer various materials for the foundation and inertial masses which enables to deliver small-scale sizes combined with high sensitivity and self frequency due to addition of a preliminary amplifier to the transducer design which amplifier is connected to the sensor elements while the manufacture method proper involves a minimum quantity of operations.
