High temperature pressure sensor for downhole pressure gauges 

Do you know what kind of pressure sensor is required for downhole pressure gauge ?You should know about PPM-S314C . S314C high temperature pressure sensor is a special pressure sensor for oil field developed by Changsha Taihe Electronic Equipment Co., Ltd. It is mainly used for downhole pressure gauges, while drilling instruments and other downhole instruments, and has 10 years of application experience in oil fields.

With the increase of drilling in deep oil and gas reservoirs, the downhole pressure gauge puts forward higher requirements for the sensor, and it needs to be suitable for the higher temperature environment and higher pressure environment downhole. Moreover, with the continuous improvement of drilling technology, higher requirements have been put forward in terms of readiness and stability. PPM-S314C has also made many improvements along with it. It can still maintain good accuracy and stability under high temperature and high pressure environment. The pressure resistance reaches 200Mpa, about 30000psi, and the high temperature resistance exceeds 200℃.

Features of PPM-S314C

1. Internal waterproof and moisture-proof treatment, can achieve IP68
2. Temperature compensation -40℃～175℃, temperature drift is 0.015%FS/℃
3. High pressure, the highest pressure can be 200MPa, about 30000psi
4. High sensitivity, sensitivity about 4mV/V
5. The structure adopts double-ring seal to ensure the sealing problem of high temperature and high pressure.
6. Small size and short length

Applications of high temperature perssure sensor

The downhole pressure gauge operates at high temperature downhole for a long time, and needs a downhole high temperature pressure sensor that can provide stable pressure output. Schlumberger downhole pressure gauges set the benchmark in the industry. Its THXR Signature Xtreme* High-Temperature Quartz Gauge can withstand high temperatures up to 437F [225℃] .This is suitable for deep wells . Conventional wells generally require high temperature resistance of 175 ℃ . The downhole instruments of Xi'an Sitan and Guizhou Kaishan Petroleum are well-known in China and provide high-quality local services. PPM-S314C is well suited to the use of downhole pressure gauges, and iteratively upgrades synchronously with the needs of first-line brands such as Schlumberger and Sitan, with strong applicability, optionality and customizability.
