<p>Hollow cylindrical body made of elastic material, used in measurement transducers to measure the pressure of a fluid, particularly a gas. According to the present invention, to eliminate the density differences due especially to temperature variations, the wall of the hollow cylindrical body (4) is provided throughout its circumference with a differing mass so as to have in the region of the oscillation antinodes a more important mass. The advantage of such configuration is that owing to the different distribution of the mass on the circumference of the hollow cylindrical body, the latter acquires already during its production process an oscillatory mode which is accurately defined. </p> |
