摘要： A pressure sensor including a housing with a sensing element therein. A communication passageway is formed in the housing. The sensing element is in fluid communication with an outside of the housing through the communication passageway. The pressure sensor is further provided with a compensating structure, so that when a contact force is increased due to occurrence of a volume expansion of a liquid passed into the housing through the communication passageway, the compensating structure is used to compensate the volume expansion. A plug may also be used with the pressure sensor. The pressure sensor is such that when the liquid within the pressure sensor has an increased volume due to being frozen, such increased volume can be compensated, so as to prevent the components of the pressure sensor from being damaged.

摘要： A method of detecting a failure in a pressure compensation system, in which a group of pressure compensators compensate volume changes of a liquid in a chamber of a subsea device, is provided. The group of pressure compensators includes at least a first pressure compensator and one or more further pressure compensators. The pressure compensators in the group are biased so that the pressure inside the pressure compensators is larger than a pressure prevailing in a medium surrounding the subsea device. Based on the detection of drift in a displacement measured for at least one pressure compensator, it is determined whether the first pressure compensator has failed or whether one of the further pressure compensators has failed, thus determining the location of the failed pressure compensator.

摘要： A gauge system and method for monitoring well pressure at temperatures in excess of 300° C. used in permanent monitoring of oil and gas wellbores. The gauge system includes an analogue output transducer and a long cable which is an extruded mineral insulated multi-core cable with a seam welded corrosion resistant metal outer sheath. The transducer is enclosed in a pressure tight corrosion resistant housing and the housing is pressure sealed to the metal outer sheath. The method includes applying signal conditioning and processing to the measurements to compensate for characteristics of the transducer, the cable and the environment and thereby provide continuous monitoring of the wellbore.

摘要： A process fluid pressure measurement probe includes a pressure sensor formed of a single-crystal material and mounted to a first metallic process fluid barrier and disposed for direct contact with a process fluid. The pressure sensor has an electrical characteristic that varies with process fluid pressure. A feedthrough is formed of a single-crystal material and has a plurality of conductors extending from a first end to a second end. The feedthrough is mounted to a second metallic process fluid barrier and is spaced from, but electrically coupled to, the pressure sensor. The pressure sensor and the feedthrough are mounted such that the secondary metallic process fluid barrier is isolated from process fluid by the first metallic process fluid barrier.
