Correflux 5420

Carryover probe gives real-time indication of particle flow changes

The Correflux™ 5420 is used as a particulate carryover probe monitoring conditions within gas recycle lines and gas discharge lines of various process vessels. The Correflux measure increases in the quantity of entrained particles within these lines to give an immediate indication of process upset conditions.

With real-time feedback of particle entrainment, reactor control can be improved, and process parameters changed to optimize process conditions and production rates. This information is also critical in protecting expensive down-stream equipment from damage caused by excessive particle carryover.

The Correflux probe is ruggedized for installation in the harsh conditions of reactor discharge lines. The sensing probe can be customized for insertion into an available port or nozzle with standard flanged connections. It is designed to withstand the impact of entrained particles and to quickly alert plant operators of upset conditions. The Correflux probe is available in either an integral or remote electronics configuration for cases with extreme process conditions such as high temperature.

PROVEN RELIABILITY

The Correflux™ 5420 probe is engineered to operate continuously 24 hours per day, seven days per week.

It is designed for the harsh environment of a polymer reactor, requiring no maintenance or spare parts. The Correflux probe measures current generated by particles impinging upon the probe. This low-level signal is proportional to the relative amount of particles hitting the probe.
