<p>A hydraulic pressure sensor, having a resilient tubular casing containing an incompressible fluid, the casing being adapted to be acted upon by an external pressure comprises a rigid tube extending lengthwise inside the tubular casing, an annular clearance being delimited between the outside wall of the rigid tube and the inside wall of the casing. The annular clearance is closed at both front ends of the casing. The tube has one end adapted to be connected to a gauge or a transformer. A plurality of radial holes are distributed over the entire length of the tube.</p> |
