Custom Designs for Subsea Pressure Transducer

The silicon material grows into the surface of the sapphire, resulting in incredible durability and stability with virtually no hysteresis and outstanding insulation properties, allowing the sensor to operate over a very wide temperature range. The excellent elasticity of the sapphire ensures high repeatability over a long service life.  

ESS, pressure testing & Hyperbaric Testing

Pre-conditioning and testing is fundamental to the success of any subsea transducer. All ESI sensors are environmentally screened and subjected to 3300 meters of submersion before leaving the factory, confirming at least 20 years of reliable service on the seabed with no concern about leakage or integrity.

Documentation & Certification

Document packages are required more frequently and are quickly becoming standard requirement within the oil, gas and subsea market. Therefore each ESI product is supplied with a complete package of documentation confirming calibration, accuracy, material conformity, hyperbaric test and ESS test certificates.

Control Valve Pressure Transducer PR3913 \ Dual Redundant Subsea Pressure Sensor – PR3915 Series

Subsea Control Valve Pressure Transmitter, ESI, USAHoused in fully welded body with Inconel 625 wetted parts, this series is intended for permanent immersion in pressurized dielectic oil and protected from ingress with a high pressure glass-to-metal lead-through. The product can withstand external pressure up to 3,000 meters water depth and provides secondary pressure containment up to 1,650 bar. The PR3915 has two silicon-on-sapphire pressure sensors and electronics for reliable dual redundancy.



Subsea Pressure Transducer, usa, florida, texasSubsea Pressure Transducer – PR3914 Series

This design is intended for permanent immersion with external pressures of up to 6,000 meter water depth, with secondary pressure containment up to 1,650 bar. Units can be supplied with hyperbaric test certificates to 3,000 meters water submersion. A range of specialist subsea connections are available.



Differential Subsea Pressure Transducer, texas, usaDifferential Subsea Pressure Transducer – PR3920 Series

The PR3920 subsea differential pressure was developed to offer high accuracy differential pressure measurement on chemical injection valves. Typically, differential pressures of 50 bar can be monitored with a high accuracy. The Silicon-on-Sapphire sensor permits high line pressures of up to 1000 bar to be applied independently to either of the two pressure ports without affecting the performance of the transducer.
