Portable GPS Current Interrupter precisely monitors corrosion.

Press Release Summary:

Mar 12, 2010 - Supplied in weatherproof case, CORI-GPS utilizes GPS technology with user-programmable, 100 ms increment interruptions for corrosion monitoring. Each portable current interrupter obtains synchronization signal via GPS satellite, and interruption can be performed with ±5 msec accuracy. This results in corrosion monitoring data with close-interval surveys along pipeline without obtaining Instant OFF readings. Also included, 60 A solid state relay avoids polarity or orientation problems.

Rohrback Cosasco Launches New Upgraded Cosasco® CORI-GPS Portable GPS Current Interrupter for Precision Corrosion Monitoring Data

Press release date: Mar 11, 2010

The latest advancement in Rohrback Cosasco corrosion monitoring solutions is the CORI-GPS. The CORI-GPS is an upgrade of portable current interrupter, which uses GPS technology with programmable interruptions for corrosion monitoring. The key improvement for corrosion monitoring is to allow the programming of synchronized interruption cycles along a pipeline using GPS, with several rectifiers connected to CORI-GPS units. Each CORI-GPS portable current interrupter obtains its synchronization signal via GPS satellite. An interruption can be performed to a programmed schedule and to a high degree of accuracy of ±5 milliseconds. This means that the corrosion monitoring data can have close-interval surveys along a pipeline without the risk of obtaining "Instant OFF" readings thus avoiding the problem of standard (Non GPS) synchronized interruptions. The GPS satellite information received is based on Universal Coordinated Time, which is converted into a 'Pipeline Time' common to all current interruption units used in a particular corrosion survey. This creates much improved corrosion monitoring data for the user.

The portable GPS current interrupter is easy to use and comes in a rugged, weatherproof case that can operate in temperatures from -5 to +50 Celcius (23-122 Fahrenheit). Power supply can be either 12V DC, or AC 115V or 240V for global use. The Cori-GPS has a solid state relay of 60 AMP avoiding polarity or orientation problems.

The interruption cycles can be set by the user in 100 ms increments and the CORI GPS can then synchronize multiple units without GPS interruption. The CORI-GPS can measure the drift in synchronization between it and a second interrupter not using GPS if required.

The CORI-GPS portable GPS current interrupter provides reliable and precise corrosion monitoring while eliminating errors of GPS interruption. The results are immediate and improved corrosion monitoring. More information and specifications can be found at
