Subsea Wellbore Pressure Plus Temperature Transducer

Stellar Technology’s Model PT36XX subsea wellbore pressure and temperature transducer delivers long-term performance in harsh subsea oil and gas exploration environments. It has a total error band of ±1% of full scale output and is designed for working pressures to 15,000 psi and seawater depths to 17,000 ft.  Both temperature and pressure sensors are located at the flush-end of the wellbore probe, a design feature that improves dynamic response and alleviates clogging.

This wellbore sensor includes dual pressure containment rated to 20,000 psi for increased reliability. In addition, the PT36XX is constructed with no external load-bearing welds thus increasing service life and improving field serviceability.

The PT36XX is constructed of Inconel and 316 stainless steel. It can be configured as a pressure only or temperature only unit. The standard unit incorporates a 3 1/16 inch API flange although customers can specify their flange of choice. Probe lengths are available in lengths of 3” to 24”.  Both probe lengths and electrical terminations are customer-specified. PT36XX is also available with dual redundant pressure sensors for extremely demanding applications.

Customers can select from numerous available electrical outputs; 4-20 mA, 0-5 Vdc, 0-10 Vdc, as well as digital outputs including RS232, RS485, and CANbus. The PT36XX is field proven with years of reliable use. Each wellbore transducer is shipped with a multi-point calibration record, traceable to NISTas standard. Material traceability is also available on request. Due to various configurations and customer-specified features contact the factory for pricing and delivery.
