Combined with the pressure balanced nature of the sensor design, the unit provides a safe, high reliability package where operators and users can be assured of high integrity data with a design life of >25 years.

The Corrosion Sensor has been designed to the highest industry standards to provide customers with dependable and accurate measurement of metal loss within a high integrity mechanical package for subsea corrosion monitoring.

The Corrosion sensor utilizes Teledyne Cormon's proprietary CEION® technology to provide extremely high accuracy metal loss detection. This high accuracy data is output in real time in engineering units, simplifying system integration. The sensor uses a flexible communications interface with outputs over either CANbus (CiA443, SIIS Level 2) or MODbus (RS485).

Key Features:

  • ​Developed specifically for high pressure and high temperature environments in deep water applications​
  • The sensors are rated to 15KSI at the maximum operating temperature. 
  • The design of the unit includes dual redundant penetrators

Benefits:

  • The real time nature of the metal loss data from this sensor allows the adoption of a pro-active corrosion management policy. 
  • Benefits can include a reduction in the use of inhibitor dosing during operation as well as reductions in the corrosion allowance at the design stage. 
  • Real-time monitoring of corrosion should play a key part in any operator's maintenance and reliability program, improving both safety and reliability across the life of the asset.
