<p>The hydraulic pressure sensor, having a resilient tubular casing (1) containing an incompressible liquid and which may be struck by an outer pressure, surrounds a rigid pipe (2) extended inside the tubular casing (1) at least approximately in the middle and in the longitudinal direction of the casing; the envelope of said pipe delimits with the inner wall of the casing a peripheral slot (3) obturated on both front sides thereof (5, 6), the inner pipe (2) having one of its ends (8) intended to be connected to a manometer or to a transformer and having a plurality of radial holes (4) distributed throughout the length of the pipe. It has been noted that, in this way, in the case of pressure sensor casings of any length and with a pressure striking the casing at any location, the same relative measured values are obtained for the same pressures. </p> |
