Roxar PTPT15K

Product catalog summary

Overview: The Roxar subsea SenCorr PTPT sensor is an intrusive, fully redundant pressure and temperature sensor designed for high-pressure environments, with a maximum pressure rating of 15,000 psi (1,035 bar). It is suitable for various applications including modeling, interpretation, simulation, well completion, and production processes.

Specifications: The sensor is available in different configurations, including PT (Pressure/Temperature) and PTPT (fully redundant Pressure/Temperature) versions. It can also be combined with other sensors such as CMPT (Corrosion), SEPT (Sand Erosion), or Force (flow momentum) sensors. The sensor uses piezoresistive measurement technology for accuracy and stability in fluctuating conditions.

Mechanical Interface: The sensor connects to pipes via an integral flange API 6A 6BX 2 1/16” with a ring gasket BX 152. It is made from Incoloy 925 and Inconel 625 materials, with a temperature range classified as KX and a material class of HH. The sensor weighs approximately 30 kg.

Electrical Interface: The sensor operates on a 24 VDC power supply, with a maximum current consumption of 100 mA at 24V. It supports communication protocols such as ModBus, ProfiBus, CanBus, and Roxar Corrocean Native Protocol, with RS485 communication to the subsea control system.

Design Specifications: The sensor is designed for water depths up to 3,000 meters (10,000 feet) and has a design life of 25 years. It can withstand a maximum shock of 10 g and a vibration level within a frequency range of 5-150 Hz.

Pressure and Temperature Ratings: The sensor has an operating pressure range of 0-1,035 bar (0-15,000 psi) and a maximum test pressure of 1,552 bar (22,500 psi). Pressure accuracy ranges from ±0.02% to ±0.1% of FSR, with an annual drift of less than 0.02% of FSR/year. Temperature accuracy is ±0.3°C or ±0.5°C within the calibrated range, with an annual drift of less than 0.1% of FSR/year.

Roxar subsea SenCorr PTPT sensor intrusive fully redundant pressure - 15,000 psi / 1,035 bar MAXIMUM RESERVOIR PERFORMANCE & temperature sensor Subsea Redundant Pressure and Temperature (PTPT) Sensor Roxar's subsea SenCorr PTPT sensors are based on piezoresistive measurement technology, which allows them to maintain accuracy and stability in fluctuating temperature- and high-pressure conditions. Two independent silicon piezoresistive sensors measure both pressure and temperature from the same measurement bridge, giving complete temperature compensation of the pressure reading and eliminating inaccuracies that may occur due to temperature gradients. The silicon sensors are placed in two high pressure oil-filled cavities using two separation diaphragms. Pressure & Temperature measurement options Roxar's subsea SenCorr Pressure & Temperature sensors are available in a PT version (Pressure/Temperature), a PTPT version (fully redundant Pressure/Temperature) or in combination with our CMPT (Corrosion), SEPT (Sand Erosion) or Force (flow momentum) sensors. Pressure & Temperature sensors available in 10,000 and 15,000 psi versions. INTERPRETATION MODELING SIMULATION WELL & COMPLETION PRODUCTION & PROCESS
