RFT Sensors

RFT Sensors

The Precise RFT (Resonant Frequency Transducer) is the most advanced electronic-free pressure sensor designed for thermal applications. The RFT sensor is offered in various temperature and pressure ranges up to 315°C (600°F) and 150 MPa (21,750 psi). Specifically designed for thermal applications, the RFT product line delivers four different temperature variations, which include the Low Temp (LT-80°C), Standard Temp (ST-140°C), High Temp (HT-260°C) and Xtreme High Temp (XHT-315°C). This diverse pressure monitoring product suite is EMI and vibration resistant with relation to ESP, PCP, and Rod Pump installations. The RFT sensor has been tested in the most demanding of environments and no matter what your application, we can provide a solution for you.

The Precise data collection system can perform ongoing sensor health checks to ensure the operator has consistent reliable data. The RFT sensor housing is corrosion resistant and we offer many different cable alloys, depending on the application.

The RFT sensor can be utilized in all types of wells, producer/injector wells, observation wells, disposal wells, and water wells.  Every RFT is calibrated and tested in-house to ensure the integrity of the sensor.

Vibrating Wire Piezometers

Bubble Tubes

Bubble Tubes

Bubble Tube systems are rugged and can withstand harsh downhole conditions caused by extreme vibration and elevated temperatures. Many of our bubble tube systems are instrumented strings that encapsulate several thermocouple points set at pre-determined locations. These are common on mechanical lift systems where the pressure at the pump is critical. In a turnkey format, Precise DHS will custom build the downhole portion (instrumented string), install the system, and commission the surface equipment according to our customer’s requirements.

Quartz / Sapphire Gauges

Designed especially for demanding hazardous environments, it is encased in robust inconel-718 housing for applications requiring a rugged sensor. The OPP-W delivers in-situ and continuous monitoring of both downhole pressure and temperature

Fiber Optics DTS/DAS/DSS

Fiber Optics DTS/DAS/DSS

Precise’s PureLight Fiber Optic Division provides an innovative and advantageous approach to monitoring techniques. As opposed to traditional sensors which provide measurements at discrete positions, fiber optic systems deliver highly accurate distributed measurements across the entire sensing length. Each fiber optic system is packaged, customized and specifically tailored to each customer’s requirements. PureLight’s fiber suite delivers reliable, robust products deployable in a variety of configurations suitable for harsh environments. Our optic systems are extensively tested and proven to deliver high product quality and are used extensively in the wellbore, pipeline and mining projects.

All fiber measurement techniques work off the premise of light scattering within the fiber optic. As light propagates through the fiber optic core, a reaction occurs between light and molecules in the glass structure. The resulting backscattered light is directly proportional to the desired measurement parameter (DTS-Temperature, DAS-Acoustics, DSS-Strain). The backscattered light is captured by the application specific fiber optic receiver module where it is analyzed. The fiber optic itself provides the sensing and transmission medium with no additional downhole sensors or splices required. For additional information please contact Precise.
