Oil, gas & subsea applications have become a speciality of ESI Technology Ltd. The ability to meet specialist requirements for the subsea market can be illustrated by the evolution of PR3913 control valve pressure transmitter which features;

 

  • Operation at 3000m submersion
  • Measures up to 1000 bar reliably for up to 20 years.
  • Constructed in corrosion resistant materials such as Inconel 625 and Titanium
  • Secondary containment to 1600bar for environmental protection should the sensor be over-pressured.
  • Certified for immersion to 3300m by means of Hyperbaric testing.
  • Subjected to Environmental Stress Screening (ESS) to ensure long term stability and extended service life.
  • Compact housing with special process connections and water-tight electrical interface.

 

Following on from the huge success of the PR3913, ESI also incorporated dual redundancy into the transmitter design. Two completely independent sensors and electronic circuits are incorporated into the existing housing to create the PR3915. This means substantial cost reduction in materials used in the construction of the valves by making them more compact. Additionally the PR3920 subsea differential pressure version was developed based on the same principle offering high accuracy differential pressure measurement on chemical injection valves.

 

At the heart of these designs is ESI’s unique Silicon-on-Sapphire sensor technology; a sensor not only with high sensitivity and stability but also rugged and resilient against high overload pressures and transients.
