Pressure Sensor For Oil And Gas

High Temperature and High Pressure Quartz Pressure Transducer  Application:● Oil, gas and geothermal well testing, ● Downhole storage logging tool, wireline logging and formation tester, ● Permanent downhole monitoring system, and permanent well head monitoring system,● Pressure testing while drilling.Instruction:Our ER-SU type High Temperature and High Pressure (HTHP) Quartz Pressure Transducer with high reliability and high accuracy, all of our quartz pressure sensors have installed the Compact and durable Inconel alloy welded bellows isolator, which not only keeps the quartz inherent excellent characteristics such as high repeatability and high stability, but also makes the quartz pressure sensor is very easy to maintain and use.The current diameters of the sensors are mainly four types--Φ25.4, Φ22, Φ19, and Φ16, the length is different due to the pressure sensor’s different models. There are two main structures, one is ER-SU series, the sensor’s line outer barrel could not withstand the pressure, it needs to be installed in the inside of the downhole instrument, the advantage is facilitating outside bus line of the sensor over the line. Specifications:SeriesRecommended applicationO.D.ER-SU 26Can be easily used for composed of the Φ 38 multi-parameter production logging, repeat formation tester. This series sensors have the same size and performance with the Quartzdyne QHB series products.Φ25.4 ER-SU 22Can be easily used for make up the Φ 32, Φ38 multi-parameter production logging tool, well test storage pressure gauge, and measurement while drilling.Φ22 ER-SU 19Can be easily used for make up the Φ 25.4, Φ32multi-parameter production logging tool, well test storage pressure gauge, repeat formation tester, and measurement while drilling.Φ19 ER-SU 16Can be easily used for make up the Φ 22, Φ25.4, Φ 32 multi-parameter production logging tool.Φ16 ER-SU 15It can be installed in limited space,specially designed for bad environment and can reach high standard requirements.Φ15The above series are all have the 150 ℃, 200℃ temperature and 60Mpa, 80Mpa, 100Mpa, 140Mpa, 175Mpa pressure products.
