Abstract

L' INVENTION CONCERNE UN PRESSIOMÈTRE COMPRENANT NOTAMMENT, SOUS LA FORME D'UNE SONDE (1) ET D'UN ÉQUIPEMENT DE SURFACE (2), UN MANCHON GONFLABLE (11), UN RÉSERVOIR (4) INDÉFORMABLE CONTENANT UN GAZ (G) ET UN LIQUIDE (L), UNE SOURCE DE GAZ SOUS PRESSION (21), DIVERS CONDUITS (31, 32), DES MOYENS DE CONTRÔLE DE DÉBIT (220-222) DE GAZ, UN CAPTEUR DE PRESSION (5), ET UN CAPTEUR DE VOLUME. SELON L'INVENTION, LE RÉSERVOIR (4) EST PORTÉ PAR LA SONDE, LE DÉBIT DE GAZ EST CONTRÔLÉ PAR UN AJUTAGE (221) ET UN CLAPET (222), ET CE PRESSIOMÈTRE COMPREND ÉGALEMENT DES MOYENS (7, 8) DE PILOTAGE DE PRESSION CONÇUS POUR OUVRIR LE CLAPET (222), LORS DE L'ÉTABLISSEMENT DE CHAQUE NOUVEAU PALIER DE PRESSION À UNE PRESSION DE CONSIGNE (KPI), PENDANT UN INTERVALLE DE TEMPS (TPI) CORRESPONDANT À CETTE CONSIGNE.THE INVENTION CONCERNS A PRESSIOMETER COMPRISING IN PARTICULAR, IN THE FORM OF A PROBE (1) AND A SURFACE EQUIPMENT (2), AN INFLATABLE SLEEVE (11), A TANK (4) INDENFORMABLE CONTAINING A GAS (G) AND A LIQUID (L), A PRESSURIZED GAS SOURCE (21), VARIOUS DUCTS (31, 32), GAS FLOW CONTROL MEANS (220-222), A PRESSURE SENSOR (5), AND A SENSOR OF VOLUME. ACCORDING TO THE INVENTION, THE RESERVOIR (4) IS CARRIED BY THE SENSOR, THE GAS FLOW IS CHECKED BY AN ADJUSTMENT (221) AND A VALVE (222), AND THIS PRESSIOMETER ALSO INCLUDES MEANS (7, 8) FOR DRIVING PRESSURE DESIGNED TO OPEN THE VALVE (222) WHEN ESTABLISHING EACH NEW PRESSURE BEARING AT A SETPOINT PRESSURE (KPI) DURING A TIME INTERVAL (TPI) CORRESPONDING TO THIS SETTING.
