Abstract (en)
The device has an inner passage (2) for a gas that is fluidically connected to a high pressure manometer (1) so as to measure the pressure of the gas in the passage. Spherical and cylindrical protection units are arranged in a passage upstream of the manometer (1). The cylindrical unit comprises a helical screw thread formed on its outer wall and is situated between the spherical units and the manometer.
