Portable solution for determining corrosion problem areas in pipelines and vessels
The Division 2 / Zone 2 corrosion data logging system complements the manufacturer’s online corrosion monitoring transmitter, allowing users to access real-time corrosion data via Ethernet, USB, SD card, or locally via videographic chart recorder. The corrosion data logging system is packaged in a portable, stainless steel enclosure weighing less than 20 lbs. The corrosion data logging system includes a HART loop converter. This device receives HART data from the corrosion monitor and delivers three distinct 4-20 mA outputs that represent general corrosion, localized corrosion, and conductance. These three variables can then be recorded and displayed on a paperless data recorder that features a full color touch screen display, up to 16 analog inputs, multiple types of media retrieval, and a Class I/Div 2, Zone 2 Ex-hazardous rating. A Type 4X stainless steel enclosure allows for the most severe of installations. The lightweight construction also permits easy mobility for the system to be moved from one location to another, where a PLC/DCS might not be available.
